The third week of April began with high winds, cold temperatures and very few migrants. With the persistent inclement weather we began to envision an immense "bottleneck" of birds to the south that would suddenly break with a shift in weather. There was no shift in the weather on the 16 and 17th and just 8 birds were banded during the two days. A near complete day of coverage on the 18th produced 10 birds banded and 12 recaptures as well as first of spring sightings of Ruddy Duck, Trumpeter Swan and Green-winged Teal. The temperatures improved on the 19th, however the wind was still from the north. Highlights of the day included observations of Merlin, Rusty Blackbird, Great Black-backed Gull and the first of many Common Terns to arrive at Tommy Thompson Park. Migration picked up on the 20th when 27 birds were banded, mainly Golden-crowned Kinglets, Hermit Thrushes and Slate-colored Juncos. The first Barn Swallows and Savannah Sparrows of the year were observed. Finally, south winds and warm temperatures returned on the 21st and a small surge of migrants was recorded. A total of 55 birds were banded on the day, which included Myrtle Warbler and Ruby-crowned Kinglet. Unusual observations included an Eastern Meadowlark and the first ever Short-eared Owl recorded at TTPBRS!
