First Week of September Brings in a Few New Species

CAWA- hatching year male
Making their final appearance in NW Ohio for the year
This week brought some northerly winds giving the appearance of fall with thrushes arriving in moderate numbers. Diversity was still punctuated by 'one of this and one of that' species, which included 15 species of warbler (Black-and-white Warbler (BAWW), Tennessee Warbler (TEWA), Magnolia Warbler (MAWA), Black-throated Blue Warbler (BTBW), Chestnut-sided Warbler (CSWA), Bay-breasted Warbler (BBWA), Blackpoll Warbler (BLPW), Ovenbird (OVEN), Northern Waterthrush (NOWA), Connecticut Warbler (CONW), Mourning Warbler (MOWA), Common Yellowthroat (COYE), Wilson's Warbler (WIWA), Canada Warbler (CAWA), and American Redstart (AMRE). Blackpoll Warblers have started their influx southward and their numbers will be increasing over the next 3 weeks.

BTBW male

Identifying flycatchers can be challenging. Here you have a small flycatcher with no eye ring, wing bars, and bi-colored beak (upper mandible is dark and lower is light, usually yellow).
EAWP: Note buffy-colored wing bars 
With no eye ring, the head appears dark. The buffy wing bars signify that this is a bird hatched this summer. We aged this bird as a Hatching Year Eastern Wood-Pewee (EAWP).

                                  Other birds of note for the week:
Cedar Waxwing (CEDW): Male has the black throat

CONW: Note the pointed tail (retrices) assisting in the aging of this bird as HY

CONW: because you cannot get enough good looks at this bird!
This coming week we should see an increase in Blackpolls, Magnolias, and Swainson's Thrushes. 

There will be two public banding demonstrations coming up on Saturday, Sept. 20th and Saturday, 27th 10:00 AM at the BSBO headquarters. Come out and see some of these visitors up close and learn about fall migration.

You can also monitor our research data on the BSBO website and read daily migration updates on BSBO's Facebook page.
