Squeaky Black-and-white Warblers

Captain Sam's- 

We had a bit more activity at Captain Sam's this morning, with a much more respectable 45 birds. Common Yellowthroats were our most abundant species; we processed 19. Gray Catbirds were our second most abundant species; we processed 10. Some of the highlights of the day included two Western Palm Warblers, an Ovenbird, and a very handsome hatch year, male Black-and-white Warbler.

A2 with separation between white tipping

We identified this Black-and-white warbler as a hatch year because of its A1 molt limit. However, the separation in the white tipping on its A2 is another indicator that this bird is a hatch year. If he was an an after hatch year, the white tipping on the A2 would be continuous.

Black-and-white warblers are unique compared to other warblers because they feed more like nuthatches- climbing up and down the trunks of trees searching for insects. Their song is frequently described as a squeaky wheel. To learn more about Black-and-white Warblers click here.

Little Bear- 

The past couple days were highlighted by some resident species that are unusual captures, and with poor migration conditions again last night, we were unsure of what to expect this morning. Turned out that our run of surprising species in the nets came to an end, but we were a bit busier than I predicted. Over half of our 39 captures were Common Yellowthroats, and we enjoyed some diversity with 13 different species overall. The forecast for the next few nights looks much better for migration along the southeastern coast, so hopefully we have some exciting new birds to share over the course of the week.
