Migration Monitoring at TTP-April 1-7

This is the first installment of weekly updates for 2005 from the Tommy Thompson Park Migration Monitoring Program. As in 2004, our first day of coverage was April 1. It has been a rather long winter so it was really nice to be outside working with birds once again! April of last year was generally quiet due to a preponderance of north winds and cold temperatures. We were pleased to find more activity during the first week of April in 2005.
 
Warm temperatures on April 1 resulted in some respectable tallies of birds including: Winter Wren (4), Song Sparrow (20), Golden-crowned Kinglet (18) and Fox Sparrow (5). A total of 37 birds were banded on the first day. Wind and various forms of precipitation forced cancellation of fieldwork on the 2nd and 3rd. Only 5 birds were banded on April 4 due to strong north winds, however, a King Eider was spotted on census which is the first record of this species for the project! The banding remained slow on the 5th however there were 23 Glaucous Gull, 3 Iceland Gull and a sleepy Long-eared Owl on this day. Migration was much more impressive on April 6 when 92 birds were banded (63 were kinglets!) and a host of new arrivals were detected. Decent numbers of Brown Creeper and Slate-coloured Junco were also evident. Favourable conditions on the 7th resulted in 100 birds being banded (75% Golden-crowned Kinglet) and the arrival of Yellow-rumped Warbler and higher numbers of Tree Swallow.
 
A total of 249 birds were banded during the first week of spring which is substantially higher than the 42 tallied in 2004
