Migration Monitoring at TTP-August 5-11

This is an update on the first week of fall migration in 2005. The station was setup on August 4 in preparation for the first day of fieldwork on the 5th. 18 birds were banded on the first day which included juvenile Eastern Kingbird, Gray Catbird, Song Sparrow and American Goldfinches. Migrants were few but a single Northern Waterthrush was captured along with 6 Yellow Warblers. The 6th featured more Traill's Flycatchers as well as early records of Swainson's Thrush and Wilson's Warbler. Also noteworthy on the day was an Indigo Bunting which was just the 8th banding record and the first fall banding record for TTPBRS.  A trickle of Yellow Warbler and Empidonax flycatchers continued on the 7th however the highlight was a very early Hermit Thrush. Hot and humid weather really put a damper on migration during the first week and was reflected in the low banding totals from the 7th-11th. Despite this there were some nice observations including singles of Tennessee, Magnolia, Blackpoll and Blackburnian Warbler. The most obvious difference between the first week this fall and previous fall seasons is the absence of Cedar Waxwing and American Robin from the banding data-set. The birds are present but are heavily concentrated on the north side of the peninsula feeding on the abundant honeysuckle berries. Most of the observations of warblers have been at this location as well. It was a quiet week overall but a good kickoff to the season and it will be interesting to see how the remainder of the fall unfolds!
