Migration Monitoring at TTPBRS-Oct 21-27

It was another interesting and enjoyable week at Tommy Thompson Park Bird Research Station as station personnel have been busy with chickadees, school groups and Saw-whet Owl monitoring in the evenings. The week began with temperatures near zero and north winds on the 21st which must have initiated some movement as 108 birds were banded including 46 Golden-crowned Kinglet, 8 Ruby-crowned Kinglet, 12 White-throated Sparrow, 9 Slate-coloured Junco and a couple of Fox Sparrows. Wind and rain from the 21st-23rd effectively shut down the lab.  Migration monitoring resumed on the 24th when an estimated 140 Black-capped Chickadee were in the count area (30 banded). The station was once again closed on the 25th. October 27th featured the arrival of Eastern Bluebird and Snow Bunting along with noticeably higher counts of Horned Lark, Purple Finch, Pine Siskin and several raptor species. A total of 7 Red-tailed Hawks were tallied on the day which is a record high total for this species at TTPBRS. In terms of banding, Black-capped Chickadee were again observed moving through the count area in flocks of between 3 and 30 birds at a time and in the end 51 were banded and 7 recaptured. Finally on the 27th 48 birds were banded which included more Chickadees and a smattering of other late fall species such as Brown Creeper, Hermit Thrush, Downy Woodpecker and 7 sparrow species. As October draws to a close we only have 2 weeks left for fall 2005 but we can still look forward to increasing numbers of winter finches, waterfowl, raptors and owls and presumably more chickadees!  November 1st and 2nd are the last scheduled dates for our "winged migration" program for schools and I should mention how enjoyable it has been showing a few birds to the kids and teaching them about bird conservation.
 
As mentioned earlier the owl monitoring is in full swing and so far we have banded 60 Northern Saw-whets and have had 5 total recaptures. Of the 5 recaptures, 4 were foreign recoveries and just 1 was a "repeat" of a bird banded at TTPBRS!
