Migration Monitoring at TTPBRS- April 22-28

Chipping Sparrow (D.Derbyshire/TRCA)

The final TTPBRS migration update for the month of April summarizes a great week of fieldwork as weather during the period was less turbulent than in previous weeks. Warm and calm conditions on the 22nd were appropriate for migrating birds as 91 birds were banded on the day. Season firsts of Northern Rough-winged Swallow and Chipping Sparrow were observed along with high counts of creepers, kinglets and juncos. Volunteers of the Fatal Light Awareness Program (FLAP) visited TTPBRS and got some great hands on training for their important rescue work in the city. Highlights of the following morning were first of spring sightings of both Pine and Palm Warblers and a sharp increase in numbers of Ruby-crowned Kinglet and White-throated Sparrow. The calm and clear weather continued through the 24th when 57 birds were banded of 15 species including a Black-and-white Warbler. Migrant activity was lacking on the 25th as just 15 birds were banded on the day although the sighting of a Northern Mockingbird was unusual for TTPBRS. Overnight on April 27, passing rain showers met with migrating birds along the north shore of Lake Ontario, which caused a "fallout" event. A total of 127 birds were banded on the following morning, predominantly White-throated Sparrows and Myrtle Warblers. The first Blue-headed Vireo and Nashville Warbler of the spring were also recorded. Clouds rolled in on the 28th and there were fewer birds evident, however there were still lots of birds to show-and-tell to enthusiastic groups from the Toronto Ornithological Club and Royal Ontario Museum.
