Friday, October 1, 2021

From Wally's report for the last week of Sept. and into Oct., there appears to be a transition from the early migrants into the later migrants. This is evident from the reduction of shorebirds and warblers to an increase in sparrows and waterfowl. Even though there has been a degradation in the shorebird habitat at A.E. Sea, Wally came up with Killdeer, Pectoral Sandpiper, Solitary Sandpiper, Greater Yellowlegs and Lesser Yellowlegs. Warblers found around the Lab included Orange-crowned Warbler, Nashville Warbler, Common Yellowthroat, Palm Warbler and Yellow-rumped Warbler. Wally didn't mention waterfowl numbers but I'm assuming their numbers are on the increase. Waterfowl found were Canada Goose, Wood Duck, Blue-winged Teal, Northern Shoveler, Mallard and Green-winged Teal. Sparrow species increased and included Dark-eyed Junco, Song Sparrow, Lincoln's Sparrow, Swamp Sparrow and Eastern Towhee (not a sparrow but close). Note - this was the first and only Dark-eyed Junco of the season, thus far. Other interesting birds found during this period were Pied-billed Grebe, Black-crowned Night-Heron, Turkey Vulture, Sharp-shinned Hawk, Cooper's Hawk, Bald Eagle, Red-tailed Hawk, American Kestrel, Eastern Wood-Pewee, Blue-gray Gnatcatcher, Marsh Wren, Eastern Bluebird, Cedar Waxwing and Rose-breasted Grosbeak.

Friday, September 24, 2021

Wally reported that this week's birding was mostly about shorebirds. With great shorebird habitat at A.E. Sea, the best numbers of these birds in many years are being found. This week's list included Killdeer, Baird's Sandpiper, Least Sandpiper, Pectoral Sandpiper, Wilson's Snipe, Spotted Sandpiper, Solitary Sandpiper, Greater Yellowlegs and Lesser Yellowlegs. According to Wally most species had multiple individuals. No other family dominated the week's list, still many good birds were found. The list included: Wood Duck, Blue-winged Teal, Green-winged Teal, Pied-billed Grebe, Chimney Swift, Sora, Sandhill Crane, Great Blue Heron, Great Egret, Green Heron, Black-crowned Night-Heron, Turkey Vulture, Osprey, Cooper's Hawk, Bald Eagle (perched below nest), Red-tailed Hawk, Belted Kingfisher, American Kestrel, Tree Swallow, Barn Swallow, Blue-gray Gnatcatcher, Marsh Wren, Eastern Bluebird, Cedar Waxwing, Song Sparrow, Swamp Sparrow, Eastern Meadowlark, American Redstart, Palm Warbler, Yellow-rumped Warbler and Rose-breasted Grosbeak. Dave

Friday, September 17, 2021

This week Wally found that shorebirds and warblers were the most productive families of migrants passing through the Lab. With the low water levels at A.E. Sea, shorebirds found there were: Killdeer, Least Sandpiper, Pectoral Sandpiper, Wilson's Snipe, Spotted Sandpiper, Solitary Sandpiper and Lesser Yellowlegs. With warbler season winding down a respectable list including Black-and-white Warbler, Tennessee Warbler, Nashville Warbler, American Redstart, Magnolia Warbler, Black-throated Blue Warbler and Black-throated Green Warbler was reported. Two Red-headed Woodpeckers were found; a juvenile in Owl's Nest Woods and an adult flying over the Main Injector coming from the Main Ring. Other highlights of the week included: Wood Duck, Blue-winged Teal, Pied-billed Grebe, Chimney Swift, Ruby-throated Hummingbird, Great Blue Heron, Great Egret, Green Heron, Black-crowned Night-Heron (an adult and juv. in the same tree as previous weeks between A.E. Sea and Sea of Evanescence), Turkey Vulture, American Kestrel, Eastern Wood-Pewee, Yellow-throated Vireo, Red-eyed Vireo, Marsh Wren, Brown Thrasher, Eastern Bluebird, Swainson's Thrush, Cedar Waxwing and a Scarlet Tanager. Dave

Friday, September 3, 2021

The lowering water levels at A.E. Sea have produced some exceptional shorebird conditions as reported by both Wally and Donna. How convenient this should happen at the height of shorebird migration. Other birds have also been attracted to the area. On one recent morning Donna reported finding 2 Sandhill Cranes, 5 Green Heron, 50 Great Egrets, 25 Great Blue Herons, 20 Wood Ducks, 8 Mallards and 1 Coot. Recent shorebirds she found in the Sea included Killdeer, Greater Yellowlegs, Lesser Yellowlegs, Solitary Sandpipers and Spotted Sandpipers. She added that there were many more outside the draw of her scope. Wally reported similar sightings including large numbers of Great Egrets and abundant shorebirds. He also had 3 Soras foraging together and repeated, Black-crowned Night-Heron sightings in the same tree. Shorebirds he found included Least Sandpipers, Semipalmated Sandpipers, Solitary Sandpipers and Lesser Yellowlegs. Dave

Wednesday, August 4, 2021

The major highlight of the morning was finding an adult Black-crowned Night-Heron in the southwest area of A.E. Sea (first of the year). The Purple Martin second brood chicks (2) had moved out of their brooding compartment up to separate compartments in the second story. They still looked too young to have fledged. Eight or more adult and immature Purple Martins were in the area of Dusaf Pond. An immature Red-tailed Hawk was begging while an adult hunted the grasslands well west of Eola Rd. Only 3 Osprey were found during the morning. A full compliment of grassland birds was found, except for Grasshopper Sparrow. Grassland birds found included Sedge Wrens, Field Sparrows, Henslow's Sparrows, Bobolinks (a molting male and a fresh juvenile), Eastern Meadowlarks and Dickcissels. Other birds of interest were Pied-billed Grebes, Spotted Sandpipers (2), Caspian Terns (2-Lake Law, 3-A.E Sea), a Great Crested Flycatcher, Marsh Wrens (less heard than in recent weeks), a Blue-gray Gnatcatcher and Cedar Waxwings. Dave

Friday, July 30, 2021

Today's highlight was finding a second brood of Purple Martins in the Dusaf Martin House. In addition, there were 5 juveniles (all on the house together several times) and 2 pairs of adults (mostly making feeding runs) buzzing the area. Only 5 of the 11 Osprey were found this morning, one of which was harassing an immature Bald Eagle over Main Ring Lake. The grasslands were noticeably quieter this week with Sedge Wrens and Dickcissels most evident, plus a couple of Henslow's Sparrows. Other good finds were Sandhill Cranes (heard near Dusaf), a Spotted Sandpiper (in a drawn down moat, about the only shorebird habitat in the Lab), Turkey Vultures (2), Green Herons (2), an American Kestrel (Bison pasture), a House Wren (carrying food) and Cedar Waxwings (Sparrow Hedge). Dave

Wednesday, July 21, 2021

Once again, the morning turned out to be all about Ospreys. A quick stop at Nest 2, on the east side of the Lab, just produced its lone juvenile feeding on a fish. After several minutes it flew off with neither adult found in the area. After a long walk in the Sparrow Hedge/Lakes Region, I wanted to check out the other Osprey Nests on the west side of the Lab. To my surprise I found six Osprey in the immediate vicinity of Nest 1. Upon Nest 1 was an adult, the next power pole contained two juveniles (I assume from Nest 1), the third pole contained one adult and one juvenile (I'm assuming from Nest 3) and finally several poles further down were a third adult (assumed to be from Nest 1). Rushing to the nearby Nest 3, I found the remaining adult and juvenile (from Nest 3) for a total of eight westside Ospreys. What I find most interesting is the apparent mingling between these two Osprey families. Upon leaving the Lab, at the East entrance, I stopped again at Nest 2. Now there were both adults and the lone juvenile, which gave a grand total of all 11 of the 2021 Fermi Ospreys. Some of the other birds of note for the morning were: Wood Ducks, Caspian Terns (at least 3), a Green Heron, Willow Flycatchers (several singing), Great Crested Flycatchers, Eastern Kingbirds, Bell's Vireos (2-appeared to be a pair), Purple Martins (still 2 at Dusaf Pond), Sedge Wrens, Marsh Wrens, a Brown Thrasher, Henslow's Sparrows, Eastern Meadowlark, Baltimore Orioles (several juveniles), a Yellow Warbler, Indigo Buntings and Dickcissels. Wally, while working a late assignment in the Lab on July 19th and 20th, reported Nighthawks foraging the skies on both evenings. Dave

Friday, July 16, 2021

Today I surveyed the status of the Osprey for a final count for the 2021 season. By next week it may be hard to determine their status as fledging has begun. Numbers are the same as last week: Nest 1 had 2 juveniles (1 fledged to nearby pole), Nest 2 had 1 juvenile (on edge of nest) and Nest 3 had 2 juveniles (1 fledged to nearby pole). This meant that the total Osprey juveniles produced for 2021 was 5, for a total of 56 for the 13 years of Osprey nesting in the Lab. The remainder of the morning was spent birding several areas around the Lab. The expected grassland birds were found were Sedge Wrens, Field Sparrows, Henslow's Sparrows (3), Eastern Meadowlarks and Dickcissels. Other highlights included Wood Ducks, Pied-billed Grebes, Yellow-billed Cuckoos (2, Sparrow Hedge and edge of Big Woods), Caspian Terns (2-again), Green Herons (2), Northern Flickers, Willow Flycatchers, a Great Crested Flycatcher, Eastern Kingbird, Purple Martins, Marsh Wrens, Cedar Waxwings and Indigo Buntings. Dave

Thursday, July 15, 2021

Wally's list of birds found during the 2nd week of July (9-16) included these highlights: Wood Duck, Green Heron, Turkey Vulture, Osprey, Cooper's Hawk, Great Horned Owl , Northern Flicker, American Kestrel, Great Crested Flycatcher, Eastern Kingbird, Sedge Wren, Marsh Wren, Cedar Waxwing, Eastern Towhee , Eastern Meadowlark, Common Grackle, Yellow Warbler and Dickcissel. Dave

Thursday, July 8, 2021

A Post-Breeding survey showed these trends (only counting birds at survey points Jun 22 to Jul 8): Sedge Wrens (up from 15 to 22), Henslow's Sparrows (up from 8 to 11), Bobolink (from 0 to 1), Eastern Meadowlarks (down from 7 to 3) and Dickcissels (down from 23 to 11). Other interesting breeding notes included spotting a family of 3 Cooper's Hawks (2-Ad and 1-Juv) in and around the Lake Law Pines. Also, found was an Eastern Kingbird nest with both parents active in the area. Other interesting birds found included: a Pied-billed Grebe, Caspian Terns(2), a Green Heron, Osprey (unfortunately Nest 2 now had only 1 juvenile while both Nest 1 and Nest 3 still had 2 juveniles), a Willow Flycatcher, Bell's Vireo, Purple Martins (still 5 around Dusaf Pond), Sedge Wrens (4 additional), Marsh Wrens (14), a Brown Thrasher, Eastern Bluebirds (3), a Vesper Sparrow, Savannah Sparrows (5), Henslow's Sparrows (2 additional), Bobolink (1 additional), Eastern Meadowlark (3-additional) and Dickcissel (4 additional). Donna mentioned seeing 2 Sandhill Cranes yesterday, July 7th. Dave

Wednesday, July 7, 2021

Wally's first week of July (1-8) was highlighted by 2 great raptors. First was a Barred Owl heard in the Big Woods followed by another sighting of one of the Peregrine Falcons at Wilson Hall. His list of other notable birds included Wood Duck, Killdeer, Spotted Sandpiper, Green Heron, Turkey Vulture, Osprey, American Kestrel, Eastern Wood-Pewee, Eastern Kingbird, Cedar Waxwing, Eastern Meadowlark, Common Grackle, Yellow Warbler, Indigo Bunting and Dickcissel. Dave

Wednesday, June 30, 2021

Probably the best bird of Wally's last week of June was a Grasshopper Sparrow found on the west side of the Lab. I had one last week in the same general area, they have been extremely rare in recent years. Other birds for the week included: Chimney Swift, Ruby-Throated Hummingbird, Caspian Tern, Green Heron, Turkey Vulture, Osprey, Northern Flicker, American Kestrel, Eastern Wood-Pewee, Willow Flycatcher, Eastern Phoebe, Great Crested Flycatcher, Eastern Kingbird, Brown Thrasher, Cedar Waxwing, Chipping Sparrow, Field Sparrow, Song Sparrow, Eastern Meadowlark, Common Grackle, Yellow Warbler, Indigo Bunting and Dickcissel. Dave

Wednesday, June 23, 2021

Even with an increasing workload fighting invasives, Wally came up with some interesting birds for the 3rd week of June starting with another look at one of the previously spotted Peregrine Falcons. Other highlights from the week's list included: Chimney Swift, Ruby-throated Hummingbird, Caspian Tern, Turkey Vulture, Osprey, Cooper's Hawk, Eastern Wood-Pewee. Eastern Phoebe, Great Crested Flycatcher, Eastern Kingbird, Blue Gray Gnatcatcher, Brown Thrasher, Cedar Waxwing, Bobolink, Eastern Meadowlark, Baltimore Oriole, Yellow Warbler, Indigo Bunting and Dickcissel. Dave

Tuesday, June 22, 2021

The second Grassland Breeding Survey of the year was performed today with results similar to the previous session. Standout birds included another Yellow-billed Cuckoo, a Caspian Tern, Bald Eagles (1 Ad and 1 Imt) and Purple Martins (4, still hanging around Dusaf and 1 in the Main Ring). There were 10 Osprey's found (Nest 1 = 2 Ad, 2 Juv; Nest 2 = 1 Ad, 2 Juv; Nest 3 = 1 Ad, 2 Juv). Other interesting finds included: Sandhill Cranes (2), Pied-billed Grebes, a Green Heron, Turkey Vultures(3), Northern Flickers (2), an Eastern Phoebe, Sedge Wrens (18), Marsh Wrens (4), Eastern Bluebirds (6), Chipping Sparrows (2), Savannah Sparrows (3), Henslow's Sparrow (9), a Swamp Sparrow, Bobolinks (2), Eastern Meadowlarks (15), a Baltimore Oriole, Indigo Buntings (3) and Dickcissels (29). Dave

Tuesday, June 15, 2021

On her way into work, Donna had an excellent sighting, a Common Gallinule (first of the year), in the area of the previous Cattail Slots (Due to high water levels, the majority of the cattails in A.E. Sea, on the south side of Batavia Rd., appear to have died). Other birds of interest in the area were: Wood Ducks (2 females each with 5 ducklings and 1 male), Great Blue Herons (3), Great Egrets (3) and several Marsh Wrens. Dave

Thursday, June 10, 2021

The first Grassland Breeding Bird Survey in two years had mixed results with some species and locations varying compared to historic results. The best highlights were another Yellow-billed Cuckoo, a pair of Red-headed Woodpeckers (very defensive of a location in the Big Woods), a Bell's Vireo (inside the Main Ring, a first there for me), Purple Martins (7) and an American Redstart (still in a historic breeding location). Eleven Osprey were found throughout the Lab (Nest 1 = 2 Ad, 1 Juv; Nest 2 = 2 Ad, 2 Juv; Nest 3 = 2 Ad, 2 Juv). Other birds of note included: Wood Ducks (43), a Northern Flicker, a Warbling Vireos (2), Sedge Wrens (18), Marsh Wrens (10), a Brown Thrasher, Eastern Bluebirds (8), a Chipping Sparrow, Field Sparrow (17), a Savannah Sparrow, Henslow's Sparrows (5), Song Sparrows (9), Bobolinks (10), Eastern Meadowlarks (13) Yellow Warblers (6), Indigo Buntings (4) and Dickcissels (30). Dave

Tuesday, May 25, 2021

With an "OK" to perform a "2021 Grassland Breeding Bird Survey" in the Lab, I was there today to do the pre-breeding portion of the survey. All the desired grassland birds were represented: Sedge Wrens (17), Field Sparrows (12), Grasshopper Sparrows (2), Henslow's Sparrows (only 2, a little disappointing), Dickcissels (8), Bobolinks (9) and Eastern Meadowlarks (16). A general census throughout the morning and early afternoon produced an about-average total of 65 species. Some remarkably interesting birds were found starting with an apparent pair of Peregrine Falcons around Wilson Hall. Other highlights included a Pied-billed Grebe, a Turkey Vulture, Ospreys (5, all 3 nests were still occupied and Nests 1 and 3 may have hatchlings), a Sandhill Crane, Yellow-billed Cuckoos (2), an American Kestrel, a Great Crested Flycatcher, Eastern Kingbirds, an Alder Flycatcher (singing near Sparrow Hedge), Purple Martins (a pair at the Dusaf martin house), a Wood Thrush, Cedar Waxwings, an American Redstart (at an historic breeding site for this species), a Vesper Sparrow, a Savannah Sparrow, a Swamp Sparrow, a buzzing Clay-colored Sparrow, Baltimore Orioles and an Orchard Oriole. Wally added the following birds to the week's tally: Spotted Sandpiper, Great Horned Owl, Downy Woodpecker, Northern Flicker, Warbling Vireo and White-breasted Nuthatch. Dave

Dave

Saturday, May 8, 2021

It was a cold start to this year's Spring Bird Count (SBC), just a few degrees above freezing. It did warm quite nicely due to the sunny and calm conditions. Increasing clouds and wind later in the afternoon again dropped the comfort level and appeared to reduce bird activity. I guess I'm trying to give reasons for our poor showing of only 78 species, but the spring, to date, has not been a migration bargain. The highlight of the small variety of waterfowl was a pair of Mute Swans on Lake Logo. Others included Canada Goose (44, including the one brooding eggs in the eagle's nest), Wood Duck (6) and Blue-winged Teal (11) and Mallard (26). Other water related birds included Pied-billed Grebe (5), Sora (6), Sandhill Crane (pr), Caspian Tern (2), Double-crested Cormorant (3), Great Blue Heron (13), Great Egret (4) and Green Heron (2). Our lone shorebirds were Killdeer (6) - we're talking very dry conditions around the Lab. One of our two best birds-of-the-day was a Peregrine Falcon, picking apart its breakfast (most likely a pigeon) near the top of Wilson Hall. Other raptors were Osprey (4, including brooding on all 3 nests), Bald Eagle (pr), Red-tailed Hawk (6) and a Great Horned Owl. Swallows, the one family well represented, included Northern Rough-winged Swallow (8), Purple Martin (pr), Tree Swallow (78), Bank Swallow (5) and Barn Swallow (43). Also flying with some of the swallows were Chimney Swifts (12). The species count of Sparrows was particularly good, but the overall numbers were small. Those found were Field Sparrow (9), White-crowned Sparrow (3), White-throated Sparrow (1), Savannah Sparrow (1), Henslow's Sparrow (2), Song Sparrow (15) and Swamp Sparrow (15). Warblers were sparse throughout the day with only 10 species found and most in small numbers. The second bird-of-the-day was a Louisiana Waterthrush (the first one found in the 2017-2021 survey period). The other warblers included an Ovenbird, Northern Waterthrush (2), a Black-and-white Warbler, a Tennessee Warbler, a Nashville Warbler, Common Yellowthroat (5), Yellow Warbler (9), Palm Warbler (22) and Yellow-rumped Warbler (11). Other birds of note included a Belted Kingfisher, a Great Crested Flycatcher, Eastern Kingbird (2), a Bell's Vireo, Warbling Vireo (5), Red-eyed Vireo (3), Sedge Wren (9), Marsh Wren (2), Blue-gray Gnatcatcher (4), Eastern Bluebird (4), a Veery (the lone thrush), Gray Catbird (12), Eastern Towhee (6), Bobolink (4), Eastern Meadowlark (13) and Baltimore Oriole (3). During the week preceding the SBC Wally reported contacting a Barred Owl on both Monday the 3rd and Friday the 7th. Dave

Wednesday, May 5, 2021

It was a treat to do some birding in the Lab today, due to the need to renew my badge for this weekend's Spring Count. Peter, Donna and I were approved to conduct the count, with restrictions. Bird activity was quite good, but migrants were not well represented, particularly the flycatchers (none found), warblers and sparrows. Sparrow found, albeit in small numbers, were Field Sparrows, White-throated Sparrows, Savannah Sparrows, Song Sparrows and a Swamp Sparrow. Warblers, again in small numbers, included Common Yellowthroat, Northern Parula, Yellow Warblers, Palm Warblers and Myrtle Warblers. All three of the original Osprey nests had female Ospreys brooding eggs. The new eagle's nest was being brooded, except the brooder was a Canada Goose (about 40 ft above ground). Other highlights included Blue-winged Teal (quite a few around the Lab), Ruddy Duck (pr), Chimney Swifts (quite a few in the Lake's Region), Soras, Sandhill Cranes (pr), a Green Heron, Turkey Vultures, a Red-eyed Vireo (new), House Wrens (new), Sedge Wrens (new, quite a few), Eastern Bluebirds and Gray Catbirds. Wally in on Saturday reported Mute Swan, Ruddy Duck, Solitary Sandpiper, Least Sandpiper, American Kestrel, Chipping Sparrow. Dave

Monday, May 3, 2021

Wally did report an uptick in the passerine migration this last week of April. His most interesting observation was: "The highlight of the week, well, I suppose it goes to my thought that I had observed something never before seen in science (I looked it up; it does happen, but rarely). A Canada Goose has taken up residence in the Bald Eagle nest. Based on seeing it in the nest 4 out of the last 6 days, I'd say she is sitting on eggs. I just think that is an awful long drop for the babies. Interestingly, the Bald Eagles are still in the vicinity." Water related birds included Mute Swan (4 in Lake Logo), Wood Duck, Blue-winged Teal, Gadwall, Ruddy Duck, Pied-billed Grebe, Sora, American Coot, Sandhill Crane, Wilson's Snipe, Spotted Sandpiper, Caspian Tern, Double-crested Cormorant, American White Pelican, Great Blue Heron, Great Egret and Green Heron. Warblers and Sparrows showed a marked increase including Black-and-White Warbler, Nashville Warbler, Northern Parula, Yellow Warbler, Palm Warbler, Yellow-rumped Warbler, Chipping Sparrow, Field Sparrow, White-crowned Sparrow, White-throated Sparrow, Savannah Sparrow, Song Sparrow and Swamp Sparrow. The bird of the week, with only one previous sighting in the Lab, was clearly a Summer Tanager. Other bird highlights included Chimney Swift, Turkey Vulture, Osprey, Cooper's Hawk, Bald Eagle, Great Horned Owl, Barred Owl, Belted Kingfisher, American Kestrel, Peregrine Falcon (3rd week in a row, "We have seen remnants of at least 4 pigeons at Wilson Hall. Potential nesting attempt?"), Horned Lark, Northern Rough-winged Swallow, Tree Swallow, Barn Swallow, Ruby-crowned Kinglet, Blue-gray Gnatcatcher, Gray Catbird, Brown Thrasher, Eastern Bluebird, Eastern Towhee, Eastern Meadowlark and Rose-breasted Grosbeak. During a brief visit on Friday, April 30 Peter Reported spotting a Merlin, a very good bird. Dave

Saturday, April 24, 2021

Here is Wally's list from Apr 19-22 (he is using the Fermi Bird List week demarcations for reporting.) There are some really nice birds included but it looks like the passerine migration is still sluggish. Waterfowl were represented by Canada Goose, Mute Swan (4 in Lake Logo), Wood Duck, Blue-winged Teal, Northern Shoveler, Mallard and Hooded Merganser. Other water related birds included Pied-billed Grebe, Sora, American Coot, Sandhill Crane, Wilson's Snipe, Double-crested Cormorant, American White Pelican, Great Blue Heron and Great Egret. Raptor type birds were Turkey Vulture, Osprey, Bald Eagle, Red-tailed Hawk, Barred Owl, American Kestrel and Peregrine Falcon. Other birds of note were Eastern Phoebe, Ruby-crowned Kinglet, Blue-gray Gnatcatcher, Brown Thrasher, Chipping Sparrow, Field Sparrow, Song Sparrow, Eastern Meadowlark and Yellow-rumped Warbler. Dave

Friday, April 23, 2021

This week (Apr 19-23) Donna reported the following interesting birds found in A.E. Sea or Dusaf Pond: a Mute Swan (only one), Wood Ducks, Blue-winged Teal, Northern Shovelers, a Spotted Sandpiper, Lone American White Pelican (two days), Great Egrets, Great Blue Herons, Pied-billed Grebes and Tree Swallows. Dave

Friday, April 16, 2021

Wally's report for April 9-15 still included a nice mix of waterfowl including Canada Goose, Wood Duck, Blue-winged Teal, Northern Shoveler, Gadwall, Mallard, Green-winged Teal, Ring-necked Duck, Lesser Scaup, Hooded Merganser and Ruddy Duck. As expected at this time of year, he mentioned finding several first-of-the-year birds including the Ruddy Duck, Caspian Tern, Brown Thrasher and Yellow-rumped Warbler. Each week recently the list of birds found has been growing. This week's highlights included: Pied-billed Grebe, American Coot, Sandhill Crane (pair has been hanging out on A.E. Sea flats), Double-crested Cormorant, American White Pelican, Great Blue Heron, Great Egret, Turkey Vulture, Osprey, American Kestrel, Eastern Phoebe, Horned Lark, Tree Swallow, Eastern Bluebird, Savannah Sparrow, Song Sparrow, Eastern Meadowlark, Brown-headed Cowbird and Common Grackle. Finally, he mentioned finding both adult Bald Eagles on the edge of the nest. He added that "it is quite possible that an adult incubating eggs could be completely hidden from view" in the nest. Hopefully, more positive info on this topic will follow. Donna added a Wilson's Snipe to the list of birds Wally found during the week. Again, it was found in the A.E. Sea Slots from Batavia Road. Wally later added a great bird that was confirmed by an independent sighting by another Lab employee, a Peregrine Falcon. Dave

Monday, April 12, 2021

Like Wally, Donna also found the pair of Mute Swans last week. In addition, she witnessed them fly from the Slots area at the south end of A.E. Sea over her head and land in Dusaf Pond. To the week's list she also added a Wilson's Snipe and a Northern Harrier along North Eola Road. Dave

Friday, April 9, 2021

Wally reported a good number of new year birds this past week. His overall best sighting was a single American White Pelican (new for year) on A.E. Sea. As he stated, "I don't think I've ever seen a lone pelican, it looked lonely." There was still a nice mix of waterfowl in the lakes including: Canada Goose, Mute Swan (new for year), Wood Duck, Blue-winged Teal, Northern Shoveler, Gadwall, Mallard, Ring-necked Duck, Lesser Scaup, Bufflehead and Common Merganser. Another highlight of his report was that now all 3 Osprey nests have birds in their areas. Other new year birds include Pectoral Sandpiper, Lesser Yellowlegs, Barn Swallow (one flying solo), Ruby-crowned Kinglet, Golden-crowned Kinglet and Field Sparrow. Other highlights for his week were: Pied-billed Grebe, American Coot, Sandhill Crane (pair has been hanging out on A.E. Sea flats), Double-crested Cormorant, Great Blue Heron, Great Egret, Turkey Vulture, Red-tailed Hawk, American Kestrel, Eastern Phoebe, Horned Lark, Tree Swallow, American Tree Sparrow, Fox Sparrow, Dark-eyed Junco, Savanna Sparrow, Song Sparrow (lots of them), Eastern Meadowlark, Brown-headed Cowbird and Common Grackle. Dave

Friday, April 2, 2021

Wally's end of the month report (Mar 29-31) included a nice mix of waterfowl though overall numbers still remain low. Waterfowl found included: Canada Goose, Wood Duck, Blue-winged Teal, Northern Shoveler, Gadwall, Mallard, Redhead, Ring-necked Duck, Lesser Scaup, Common Merganser and Red-breasted Merganser (pair, new for year). In the good news department, Wally spotted 3 adult Bald Eagles in the area of the nest. Unfortunately, they were not seen near but not at the nest. Conversely in the bad news department, Wally mentioned that in the aftermath of one of the prescribed burns, an active American Woodcock nest was found destroyed by the flames. His bird of the week was a Brown Creeper (new, year). He mentioned that this species had been eluding him until now. His other major highlight was noting that the Ospreys have returned to both Nest 1 and Nest 2. Some of the other birds mentioned were American Coot, Killdeer, American Woodcock, Double-crested Cormorant, Great Blue Heron, Turkey Vulture, Bald Eagle (an additional juv.), Cooper's Hawk, Northern Flicker, American Kestrel, Eastern Phoebe, Horned Lark, Eastern Meadowlark, Brown-headed Cowbird and Common Grackle. Dave

Monday, March 29, 2021

Wally added another 2 new year birds to the Lab this past week (Mar 22-26), including a near, on schedule Eastern Phoebe and a late arriving Common Grackle. The disturbing portion of his report was that he did not find the Bald Eagles this past week and had not seen them on the nest for some time. This would most likely place them out of the nesting period for the year. Though he stated there were not a large number of waterfowl around, he did have good variety including: Canada Goose, Wood Duck, Blue-winged Teal, Northern Shoveler, Gadwall, American Wigeon, Mallard, Ring-necked Duck, Lesser Scaup and Common Merganser. Other interesting finds for the week were: Pied-billed Grebe, American Coot, Sandhill Crane, Double-crested Cormorant, Great Blue Heron, Turkey Vulture, Barred Owl (Adam found again), Hairy Woodpecker, American Kestrel, Tree Swallow, Eastern Bluebird, American Tree Sparrow, Fox Sparrow, Dark-eyed Junco, Song Sparrow, Eastern Meadowlark and Brown-headed Cowbird. Dave

Sunday, March 28, 2021

Donna's weekly report included 2 new year bird species including a Great Egret and a number of Tree Swallows. Waterfowl diversity was down a little. Those found were Canada Geese, Mallards, Wood Ducks, Northern Shovelers, Ring-necked Ducks and Common Mergansers. Other highlights included a pair of Pied-billed Grebes, a possible pair of Sandhill Cranes and a Great Blue Heron. All these birds were found in A.E Sea or Dusaf Pond. Unfortunately, the cattails on the south side of Batavia Road in A.E. Sea have not yet emerged. The Slots, that were cut several years ago in these cattails, were a great habitat for marsh birds. It is hard to tell whether this habitat will return. Finally, along North Eola Road, Donna found 2 Northern Harriers (hunting the fields) and Eastern Meadowlarks. Dave

Tuesday, March 23, 2021

Wally's report from the week of Mar. 15-19 stated that waterfowl numbers appeared to be down but still with some diversity.

Donna reported mostly waterfowl and water-related birds again this week, with a pair of Canvasbacks (new for the year), as her top bird. They were found in Dusaf Pond along with several Lesser Scaup (I'm assuming they were) and Common Mergansers. Across the road, at A.E. Sea, she found Northern Shovelers, more Common Mergansers, a Pied-billed Grebe, and an American Coot. Along North Eola Road she found a couple of Eastern Meadowlarks and an American Kestrel on the kestrel nest box. Dave
