MIGRATION SUMMARY FOR SEPTEMBER 5th - 11th, 2008

 

Pelee Island Bird Observatory (PIBO)

 

 

There were no large ‘fall-outs’ at the Point this week and rainy weather affected coverage at the start of the summary period, but there were still lots of migrants recorded at the station from the 5th – 11th and the PIBO crew kept busy both on the census and in the netting area.

 

Shorebirds continued to move through the area in small numbers, with eleven species noted including the first Black-bellied Plovers and Baird’s Sandpipers of the Fall. Hawks and waterfowl were scarce, however, with the exception of ones-and-twos of Osprey, American Kestrel, Northern Shoveler and Redhead.  

 

The first significant waves of autumn thrushes arrived this week when hundreds of birds were heard migrating overhead on the evening of the 5th followed by lots of activity at the Point on the morning of September 6th. Forty-five thrushes were banded on the day and Swainson’s Thrushes, especially, continued to arrive on-and-off throughout the week. In all, 122 Cathurus thrushes were banded from the 6th – 11th (89 Swainson’s, 20 Gray-cheeked and 13 Veerys). In keeping with the rapid turnover of songbirds at the Fish Point study site, just one on these birds was recaptured at the station in the days following its initial capture.       

 

Magnolia Warblers and American Redstarts were the most common of twenty warbler species tallied during the week along with good numbers of Black-throated Blues and Northern Waterthrushes. Two banded Northern Parulas and a young, male, Hooded Warbler were both ‘firsts’ for the Fall. In addition to the warblers, a nice variety of other songbirds were recorded including the first Olive-sided Flycatcher, Philadelphia Vireo and Ruby-crowned Kinglets of the season. A Rock Dove recorded on September 10th was new for 2008!

 

A total of 92 species was recorded at the Point this week during the official count period compared to 91 last week and thirteen Fall ‘firsts’ were noted, which brings the Fall species total to 118. In all, 245 birds were banded along with five recaptures in 294 net-hours, for an average catch-rate of .85 birds/net-hour.
