Migration Monitoring Update-Oct 28-Nov 3

Migration has slowed considerably at Tommy Thompson Park although numbers of blackbirds, pipits, larks and Snow Buntings have been significant as have the surging counts of waterfowl. On October 28th, 54 birds were banded of which 22 were Black-capped Chickadee. A single Blue-headed Vireo along with 5 Hermit Thrushes were also banded that day. Red-winged Blackbird reached a season high count of 434 and Common Grackle peaked at 54. October 29 was probably our last busy day of the fall as 104 birds were banded of which 86 were chickadees! An average of 6 birds were banded from October 30-November 1st and it was evident that the flocks of Chickadees, kinglets and sparrows had passed us by. October 30th was a good day for gulls at the station as our first ever Thayer's Gull was observed and several Bonapartes were spotted. A late Cape May Warbler was recorded on the 31st. November was very quiet during the previous two fall seasons at the station and 2005 is certainly falling in line. Juncos and American Tree Sparrows are perhaps the most conspicuous landbird species in the area although we have never seen a big push of these species in November. November 2nd was another good day for flyovers as 360 Red-winged Blackbirds were counted along with 48 Snow Bunting and several Rusty Blackbird and House Finch. Weather has been unfavourable for Owl Monitoring and as such our banding total remains the same as last week although there may be some good conditions before the end. Only a week remains for fall 2005 and we are hoping for some late movement and perhaps a few new species for the season.
