MIGRATION SUMMARY FOR

SEPTEMBER 26th - OCTOBER 2nd,   2008

 

Pelee Island Bird Observatory (PIBO)

 

Migration activity was fairly low-key at the Point during the final days of September and early October, yet cool weather and steady north winds made for a reasonably busy time and a nice variety of birds (82 species) were recorded during the official count period. Typical late-Fall migrants were counted in moderate numbers including both kinglet species, Yellow-rumped Warbler, and White-throated Sparrow, along with ones-and-twos of Brown Creeper, Red-breasted Nuthatch and Winter Wren.    

 

Fourteen warbler species were noted during the week and thrushes continued to filter through the area, with Hermit Thrushes starting to outnumber the Swainson's and Gray-cheeked. The first significant wave of Blue Jays arrived on the 26th, with 418 birds tallied on the morning census.

 

Shorebird activity tapered off - four species were observed this week - and many early-Fall migrants such as orioles and most of the flycatchers and swallows were entirely absent. At the same time, a number of species made their first Fall appearance including Hermit Thrush (Sept. 26th), Slate-colored Junco (27th), Scarlet Tanager (29th) and Dunlin (30th).        

 

PIBO's Northern Saw-whet Owl monitoring project got underway on the evening of October 2nd at a new survey site near the PIBO staff house. While no saw-whets were detected, we're confident the new location will prove to be a suitable (and practical) setting for future monitoring efforts.

 

A total of 82 species was recorded at the Point this week during the official count period compared to 81 last week and there were six Fall 'firsts', which brings the Fall species total to 143. In all, 143 birds were banded along with one recapture in 294 net-hours, for an average catch-rate of .49 birds/net-hour.
