Migration Monitoring at TTP-May 20-26

The week started off on a quiet note with 41 birds banded on the 20th. The highlight of the day was the 31 Grade 7 students who participated in our Bird Studies at Tommy Thompson Park Program. The first Cedar Waxwings (4) appeared on this day along with 2 late Pine Warblers. Warm and calm conditions on the 20th led to 80 birds banded on May 21. Bulk species from the nets were Swainson's Thrush (16), Ovenbird (9) and Northern Waterthrush (8). From the 22nd-25th ground level migration wound to a halt as cool and "northwindy" (new word!) weather swept into the Toronto area. A Juvenile American Woodcock was banded on the 22nd which is evidence of this species having bred successfully right under our noses. Migrants were scarce on the 24th as the capture totals reached a May low of 6! There were a few more birds to see on the 25th and luckily we were able to find our first Ruby-throated Hummingbird of the spring! Normally this species is a regular migrant at TTPBRS with 10-20 birds turning up in the nets from the first week through the third week of May. Continuing the trend of late arrivals and near "no shows" are Vireos and Flycatchers and a couple of warbler species. Thus far census and banding totals have been particularly meager in 2005 for Philadelphia, Blue-headed and Red-eyed Vireo as well as Mourning and Black-throated Green Warbler. The first Tennessee Warbler of the season was banded on the 25th along with singles of Bay-breasted and Blackburnian and another Wood Thrush. The wind abated on the evening of the 25th which brought in another influx of migrants into Tommy Thompson. 86 birds were banded on the 26th which included 9 Gray Catbird, 12 Magnolia Warbler, 2 Mourning Warbler, 1 Indigo Bunting and 6 Lincoln's Sparrow. The most unusual sighting on the day was a Black Tern which was a first for TTPBRS and a rare sighting in the Toronto area!
