MIGRATION SUMMARY – OCTOBER 24th TO 30th, 2007

 

Pelee Island Bird Observatory (PIBO)

 

 

There were lots of migrants in the area this week compared to the previous seven-day period – eight-one species were recorded between October 24th – 30th compared to fifty-nine from the 17th – 23rd. While there were no dramatic fall-outs, kinglets and other late-autumn migrants were numerous at the start of the summary period and remained active through much of the week. Northern Saw-whet Owls were captured on five evenings as well, with twenty-two birds banded (including two foreign encounters), along with an Eastern Screech Owl.           

 

October 24th     

 

It was active at the Point this-morning with a variety of species noted including five raptor spp., Eastern Phoebes, Blue-headed Vireos, kinglets, an Orange-crowned Warbler, Purple Finches, and six sparrow spp.  Forty-eight species were recorded and 64 birds of fifteen species were banded – mostly Ruby and Golden-crowned Kinglets, Hermit Thrushes and Yellow-rumped Warblers. The first Bufflehead of the Fall was recorded and a late Indigo Bunting was banded.  

 

October 25th   

 

Another busy day at the Point with good numbers of Golden-crowned Kinglets (42 banded) and still lots of Ruby-crowns, with twenty-three captured. Other migrants on the day included Common Loons, Brown Creepers, Palm Warblers and lots of Red-winged Blackbirds and Common Grackles.    

 

October 26th       

 

Although light rain and east winds affected the morning coverage, kinglets were numerous on the census and in the netting area, along with moderate numbers of Yellow-rumps and White-throats. Two Horned Grebes and six Dunlins at the tip were new for the Fall.   

 

October 27th       

 

More rain with strong west winds throughout the day. Not many birds in the area with the exception of two Black-bellied Plovers, a trio of Sanderlings, some kinglets, small numbers of sparrows, and the first Ruddy Ducks of the season.     

 

October 28th        

 

It cooled off overnight and a season-low dawn temperature of 3° C helped make for an active morning. Forty-nine species were tallied including good numbers of Blue-headed Vireos, American Crows, Cedar Waxwings, Rusty Blackbirds and Purple Finches. A Red-shouldered Hawk was new for 2007. Eight Northern Saw-whets and an Eastern Screech Owl were banded in the evening.   

 

October 29th     

 

Migrants were active again this-morning with forty-one species recorded including lots of American Robins and Yellow-rumped Warblers, smaller numbers of kinglets, White-throated Sparrows and blackbird spp., and a late Red-eyed Vireo. While waterfowl have been late arriving this Fall, Double-crested Cormorant numbers have remained unseasonably high – 4000 birds were counted on census.  

 

October 30th       

 

A nice variety of species were noted today in small numbers including Peregrine Falcon, both nuthatch spp., Winter Wren, Eastern Bluebird and Fox Sparrow. A Whip-poor-will was observed on the road first thing this-morning. While today’s cormorant count was just 47 birds, European Starlings made-up for this shortfall, with more than 3000 individuals reported during the count period!      

 

Eighty-one species were recorded at the Point this week compared to fifty-nine last week and six Fall ‘firsts’ were tallied, which brings the season species count to 167. In all, 263 birds were banded (not including 23 owls) and three recaptured during 312 net-hours for a catch-rate of .84 birds/net-hour.
