Migration Monitoring at TTP-October 21-27

Numbers dropping but excellent birding and a couple of goodies.....
 
We are now past the peak of fall migration in southern Ontario although daily banding totals are still above average. Even though we are past the peak of songbird migration, we still have much to look forward to such as the arrival of late fall passerines (e.g. American Tree Sparrows, Snow Buntings, Redpolls), Raptors (e.g. Northern Goshawk, Rough-legged Hawk), Owls and perhaps a few more surprises.
 
The week has been fairly steady in terms of daily banding totals as we are averaging approximately 50 birds/day. Kinglets, Hermit Thrush and Slate-coloured Junco were the primary species captured on the 21st when 83 birds were banded. Another 77 birds were banded on the 22nd and 86 were banded on the 23rd. Poor weather on the 24th resulted in only 23 birds being banded and 18 recaptured. This was rather fortuitous as it gave us ample opportunity to spend time with park visitors for the Tommy Thompson Park Fall Bird Festival. The banding demonstrations are becoming a staple at TTPBRS and are extremely rewarding for both the visitors and station personnel! Heavy fog on the 25th resulted in high detection but few captures as Myrtle Warblers and Kinglets were observed feeding at canopy level on insect clouds. A White-eyed Vireo banded on the 26th was the first of this species ever recorded at TTPBRS! The bird was recaptured again today along with a late Gray Catbird, Magnolia Warbler and Nashville Warbler. The highlight for today was the second record of Yellow-breasted Chat for TTPBRS. The first record was October 6 of this year. The bird was heard singing near net 3 just off the road and was not relocated.
