Migration Monitoring at TTPBRS- May 6-12

The second May update on migration monitoring at TTPBRS in spring 2007 summarizes a week that began with just a few drops of warblers and other neotropical migrants and ended with a flood! North winds on the 6th reduced bird numbers at TTPBRS, although there were still plenty of birds for our second training day of the season with FLAP volunteers. Good numbers of Ruby-crowned Kinglet, Hermit Thrush and a late Brown Creeper indicated that things were a little behind schedule. Conditions overnight were calm, which enabled a large volume of birds to pass over. The result was a very quiet morning on May 7th as just 15 birds were banded. A few 'new' warblers did choose to drop down on the lakeshore including Black-throated Green, Magnolia, Blackburnian, Hooded and our first ever Prothonotary Warbler! Tommy Thompson Park was 'flown over' again on May 8th as relatively few birds were evident despite heavy traffic on NEXRAD doppler radar overnight. Eastern Kingbird, Warbling Vireo and Common Yellowthroat were new for the spring. Migrant activity picked up a little on May 9 when 59 birds were banded including 4 Wood Thrush, 3 Gray Catbird and 5 Lincoln's Sparrow. Overnight rain on May 10 caused a significant grounding of migrants, resulting in 149 birds were banded and 18 warbler species recorded, including our 2nd Hooded Warbler of the spring. White-throated Sparrow, Least Flycatcher, Swamp Sparrow and Ovenbird were particularly abundant in the count area that morning. May 11 was a memorable day as a total of 95 species were recorded in 6 hours at TTPBRS, a new one-day record. A total of 184 birds were banded and 12 new arrivals were noted, including White-eyed Vireo, Scarlet Tanager, Indigo Bunting, Golden-winged Warbler, Black-billed Cuckoo and a stunning male Yellow-throated Warbler! An impressive 25 warbler species were observed during the morning. May 12 was the Spring Bird Festival at Tommy Thompson Park and over 150 participants were in attendance. There was lots of activity remaining from the previous day providing great opportunites for the public to view birds in-the-hand at TTPBRS!
