Exotic Birds Seen at Fermilab

The following bird species have been recorded on the Fermilab site, but have not been included in the site list since they are almost certainly escaped from captivity. Feral breeding populations are not known to exist in the area and they are extremely unlikely to have arrived here naturally.

Egyptian Goose
This non-migratory species from Africa is often kept in waterfowl collections and has been seen twice on site among flocks of migrating Canada Geese. The first record was from Main Ring lake and the second was from the bison field.

Ruddy Shelduck
This is a rare eurasian species which is also popular with waterfowl collectors. In February of 2003 one was found on Main Ring Lake.

This european game bird has well established feral populations in the Rocky Mountains States and is popular with aviarists. One was seen crossing the road in the village in October, 2010 and another was seen along the bike path across from the Bison Field in October, 2013.

This small cockatoo is native to Australia and is a very popular cage bird. One was found perched on Wilson Hall late in September, 2005.

Nanday Parakeet
Also called "Black-headed Conure" this parrot is native to South America and was seen on site near the intersection of Eola rd. and Wilson st.

This small Australian parrot is a very popular cage bird that was seen feeding in the grasses by the Bison Wallow

Common Waxbill
A popular cage bird, this African species was found in the center of the main ring.

Yellow Grosbeak
This bird was seen on site during on Dec 15, 2001, during the Christmas Bird Count. This species normally occurs in Central America and occasionally strays across the Mexican border into southern states such as Arizona. The only other record from northern states (that I am aware of) is on from Iowa which was found in the winter of 1995. Given the paucity of records this far north and the potential for this species to be kept in aviaries one has to assume that this was an escaped bird. However, it is not inconceivable that it was a genuine vagrant.

European Greenfinch
This European finch has been introduced into both Australia and South America and is regularly reported in the U.S. One was found along Eola rd. in April, 2005.
