Migration Monitoring at TTPBRS-Sept 16-22

The seventh week of fall migration was our busiest of the season so far as high numbers of thrushes, warblers and White-throated Sparrows were on the move. The week also featured some passage of vireos (mostly Red-eyed), flycatchers, kinglets and creepers. In all 343 birds were banded during a week filled with strong northerly winds. High winds associated with a cold front on the 16th cancelled banding coverage on that day. Bird activity was noticeably higher on the following morning as 101 birds were banded. There was a sharp influx of Northern Flicker (20 DT), Gray-cheeked Thrush (28), Myrtle Warbler (65) and White-throated Sparrow (45). Raptors were also moving through on the 18th which resulted in our first ever capture and banding of a Northern Harrier! A small surge of late fall migrant species such as Brown Creeper, Ruby-crowned Kinglet and Winter Wren arrived on this day. On the shorebird front, Sanderling, Semipalmated Plover and the same Red Knot reported last were recorded on a daily basis during the week. September 19 was another solid day of migration monitoring as 91 birds were banded of 23 species. Our second ever Hooded Warbler was captured and released unbanded on this day (species at risk are now released unbanded). Also on the 19th the first Semipalmated Sandpipers for the TTPBRS checklist were observed on the beach.  The 20th was reported as a mega-day for migration monitoring stations at Long Point Bird Observatory and Prince Edward Point Bird Observatory however winds were too strong here in Toronto which resulted a census but no mist-netting. Winds shifted to the south and west for the 21st and 22nd respectively which meant fewer birds but still some excellent variety. Winds were apparently favourable for Blue Jays on the 22nd as 470 were recorded on the day which is a season high so far. Fall migration is about to kick into high gear as we near the peak at Tommy Thompson Park (late September-mid October) so look forward to some bulky reports in the coming weeks!
