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

they are extremely unlikely to have arrived here naturally.
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.
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

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.
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,
