September 9th – The Migrants Ebb and Flow

The star of the Fall has to be the Bobolink. They are attracted to the prairie grasses and we’ve seen up to 100 – and banded 80. -KDC


We’ve been busy, banding on 6 of the last 7 days. Each day is different both in terms of numbers banded and in the variety of birds seen at the site. But two species have been consistent: Bobolinks and Indigo Buntings. Part of the prairie field was mown with a wide swath left down the middle (more or less) and another along the pond/woodland edge. We cut 2 net lanes through the middle swath and they have been very effective catching Bobolinks and, to a lesser degree, Indigo Buntings – we’re also picking the latter up in nets along the edge. Both species are seed-eaters; the Bobolinks are fattening up for the long journey to Argentina and the buntings are finishing off their moults before heading for southern Florida and Central America.

And the field has LOTS of food!

The field after baling. the thick grasses yielded 25 big round bales. -MEG


Below, to simplify things (for me), I’ll list the birds banded each day and throw in a few pictures. We’ve had a number of very helpful volunteers…who also take good photos.

On good weather days we’ve had the luxury of banding outside. Here Elaine is scribing for Andy. -DOL
