MIGRATION SUMMARY – OCTOBER 3rd – 9th, 2007

 

Pelee Island Bird Observatory (PIBO)

    

There were very few migrants recorded at the Point this week with the exception of one or two mornings at the start of the summary period. The station was very quiet compared to previous years – the average catch-rate this week (.31 birds/net-hour) is down 87% compared to the same period in 2006 (579 birds banded in 247 net-hours for a catch-rate of 2.34), and 81% compared to the three-year average (2004-2006). The average dawn temperature from October 3rd-9th was 19 C, which helps explain the lack of bird activity during the course of the summary period.

 

Six raptor species were tallied this week including three Peregrine Falcons, along with five woodpecker, six thrush and thirteen members of the warbler family. Fall ‘firsts’ included Red-breasted Merganser, Eastern Phoebe, Eastern Bluebird, Orange-crowned Warbler and Eastern White-crowned Sparrow.       

 

Seventy-four species were recorded at the Point this week compared to eighty-one last week and five Fall ‘firsts’ were tallied, which brings the season species count to 154. In all, 116 birds were banded and four recaptured during 370 net-hours for a catch-rate of .31 birds/net-hour.

 

Due to PIBO staff’s attendance at the Canadian Migration Monitoring Network biannual meeting in Slave Lake, Alberta, regular daily reports are not included in this weekly update.
