MIGRATION SUMMARY FOR OCTOBER 3rd - 9th, 2008

 

Pelee Island Bird Observatory (PIBO)

 

 

Cool weather on October 3rd and 4th made for a busy time at the Point until the 6th, but then south winds, rain and balmy conditions produced a decline in activity towards the end of the summary period. Kinglets, Hermit Thrushes, Yellow-rumped Warblers and White-throated Sparrows were the most common birds encountered this week along with a nice assortment of other species.

 

While warbler diversity dropped off - thirteen species were recorded during the summary period - new arrivals for the Fall continued to appear including 'firsts' for Northern Saw-whet Owl (Oct 3rd), Orange-crowned Warbler (5th), Swamp Sparrow (5th), Common Loon (7th) and Rusty Blackbird (7th). More species were documented at the station this week (83) than in the last week of September and early-October (82), which is unusual.

 

Ruby and Golden Crowned Kinglets were quite active on the 5th, with 45 and 31 individuals tallied on the day, respectively, included thirty-two banded. In all, 81 birds of seventeen species were captured on October 5th followed by 54 banded birds of twenty-two species on the 6th. Other species of note this week included the first Lesser Scaup (October 6th) and Green-winged Teals (7th) of the Fall, a Peregrine Falcon (6th), Pine Warbler (6th), and a somewhat tardy Indigo Bunting (6th).

 

It remained fairly active on the 7th, with 41 birds banded including a young male and female Sharp-shinned Hawk, but steady showers and warm southerly winds on October 8th made for a very quiet morning, with just the 90-minute census conducted in a heavy downpour. There was not much to report on the 9th with the exception of an exciting find - a Short-eared Owl - near the PIBO cottage in the early afternoon.         

 

A total of 83 species was recorded at the Point this week during the official count period compared to 82 last week and there were seven Fall 'firsts', which brings the Fall species total to 150. In all, 248 birds were banded along with one recapture in 326 net-hours, for an average catch-rate of .76 birds/net-hour. Three Northern Saw-whet and two Eastern Screech-Owls were banded on the evenings of the 4th, 8th and 9th.
