Atlantic Flyway review: Region IV Piedmont-Coastal Plain, Fall 2007

North American Bird Bander



Region IV welcomed another coastal station in 2007 with a report from Chris Snook at Charleston, South Carolina.

The season was hot and dry throughout Region IV except in Florida where precipitation averaged above normal. Banders blamed their poor success on the lack of cold fronts in August, September, and the first half of October and on persistent strong east winds that blew the migrants farther inland. At Bill Baggs State Park in Miami no significant cold fronts were encountered until 25 Oct, and then on 29 Oct they banded over 100 Black-throated Blue Warblers that should have been on their West Indian wintering grounds by that date.

Myrtle Warblers continued to be the most commonly banded species in Region IV, although numbers were down considerably from the previous autumn; their age ratios ranged from 25% hatching year (HY) at inland Tallahassee to 100% HY at coastal Chincoteague. Gray Catbird, which made the top ten list at all11 stations, was in second place, with percent of HYbirds ranging from 54% at Laurel to 95% at Chincoteague.

Peak migration days ranged from 19 Sep in Laurel to 14 Nov at Kiptopeke, with five stations reporting their peak during 10-15 Oct.

Thanks to the dedicated banders and assistants who contributed 61,825 net-hours in autumn 2007 to band 22,424 birds in Region IV. Thanks also to colleagues Deanna Dawson and John R. Sauer for their helpful comments.
