Fall Migration at TTPBRS-Aug 5-11, 2006


This is the first update on Migration Monitoring at Tommy Thompson Park for fall 2006. Weekly news and sightings from the station will be distributed each Saturday through November 12. As always you can follow the migration at TTPBRS by visiting our sightings board which is updated on a daily basis. http://ttpbrs.blogspot.com

Mist nets were setup and trails and lanes were cleared on the 4th in preparation for the first day of fieldwork on the 5th. The vegetation at the park is very dense which made for a long and arduous day which would have been more difficult if not for the help of volunteers Don Johnston, Larry Menard and Andrew Jano (thanks guys!). The first day was characterized by hot and humid conditions with winds from the south which meant few birds were moving. August typically features localized movement of post-breeding young and adult birds, however the most interesting aspect of the first week was a noticeable lack of local breeders, particularly Yellow Warblers. It seemed as though many birds finished nesting early this year and left Tommy Thompson Park to finish moulting in other locations. A total of 38 birds were banded on the 5th which was dominated by young and boisterous European Starlings. Highlights of the day were observations of Black-billed Cuckoo and Eastern Meadowlark and the banding of a Rose-breasted Grosbeak and Wood Thrush. More south winds and more empty net rounds were a feature of the 6th through the 9th although there were a few birds trickling through such as Ovenbird, Nashville Warbler, Northern Waterthrush, Canada Warbler and Yellow-bellied Flycatcher. The all important winds shifted to north on the 10th which increased the number of birds at TTPBRS. A decent push of Warbling Vireo was observed on this day and an early Swainson's Thrush was banded. August 11 was noteworthy in that this was the first day that felt like fall migration was underway. A total of 30 Yellow Warblers, 18 Myrtle Warblers and over 100 Red-winged Blackbirds were recorded. Singles of Blackburnian Warbler, Bay-breasted Warbler and an early Slate-coloured Junco were also noted.

The first week went very well and we are all looking forward to another great season at Tommy Thompson Park Bird Research Station!
