MIGRATION SUMMARY FOR NOVEMBER 7th - 15th, 2008

 

Pelee Island Bird Observatory (PIBO)

 

 

PIBO's 2008 monitoring season wrapped-up on November 15th after 107 consecutive days of Fall field coverage at the Point. It was blustery and cold during most of the summary period, with strong winds from the west and northwest, along with sub-zero temperatures, showers and snow squalls towards the end of the week.  

 

Migration activity was up and down with the weather and daily coverage was reduced to the morning census and some additional observations on a number of days due to rain and snow. At the same time, a nice variety of species was recorded including season-high counts of 14 Tundra Swans (Nov. 11th), 863 Red-breasted Mergansers (9th), 102 Buffleheads (14th), 5 Northern Harriers (11th), 51 American Pipits (12th) and 25 American Tree Sparrows (15th).

 

Nine waterfowl species were noted including the first Hooded Mergansers of the Fall along with small numbers of scaup, Mallard and Common Goldeneye. Although migrant songbirds were generally scarce, some kinglets, creepers, Winter Wrens and Hermit Thrushes were recorded on a daily basis and seven sparrow species were tallied from the 7th - 15th. Diurnal migrants were active - 2600 Common Grackles, Rusty, and Red-winged Blackbirds were counted heading south on the 11th as well as  smaller groups of Cedar Waxwings, Pine Siskins and American Goldfinches.

 

A total of 60 species was recorded at the Point during the official count period compared to 67 last week and there was one new arrival, which brings the final Fall species total to 171. In all, 34 birds were banded along with three recaptures in 44 net-hours, for an average catch-rate of .84 birds/net-hour.

 

Another productive and enjoyable year of field research on Pelee was made possible thanks to the critical support of all of PIBO's friends and supporters. Full details and acknowledgements - along with all the exciting new developments at PIBO in 2008 - will be included in the observatory's year-end report. The report will be available online before Christmas. On behalf of the entire field crew, thanks for all your support and best wishes for the Holiday season!
