MIGRATION SUMMARY – AUGUST 1st TO 7th, 2007

 

Pelee Island Bird Observatory (PIBO)

 

 

PIBO’s 2007 Fall migration monitoring season got underway at Fish Point on August 1st. It was a warm muggy start to our 5th year of autumn coverage – the dawn temperature hovered around twenty degrees centigrade with accompanying clear skies and high humidity.

 

Local breeding birds and young were quite active during the summary period and a few early migrants were noted including Semipalmated Plover, Pectoral Sandpiper, Ruddy Turnstone and Sanderling, among others. A Willet was observed on census on August 7th. Approximately 400 Common Terns and 1000 gulls of four species were tallied at the Tip on a daily basis.

 

Other migrants encountered during the week include Yellow-bellied Flycatcher, Swainson’s Thrush and Northern Waterthrush. Purple Martins and Barn Swallows were fairly active as well. A number of local birds were captured including an adult female Indigo Bunting originally banded at the station in September 2004.

 

Four staff and volunteers participated in the fieldwork this week and tallied sixty species in the count area during the standard morning coverage period. Just nineteen birds of ten species were captured in 301 net-hours of operation for a catch rate of 0.06 birds/net-hour.
