Giant Swallowtail caterpillars

Since 2006 there have been more and more sightings of Giant Swallowtail butterflies  (Papilio cresphontes) in our region, and now the caterpillars can be found on prickly ash, one of their favourite food sources.  September is the month to find mature caterpillars, fattening up before forming cocoon or chrysallis, or crawling into some crevice or shelter and overwintering as caterpillar.  The Giant Swallowtail caterpillar resembles a big bird dropping, helping to camouflage it from predators.  Another tactic to ward off predators is by popping out bright red tentacle-like osmeterium.  Caterpillars in the photos below were found north of Perth Road Village.

Kingston Area Birds to September 9, 2011

September welcomes back migrating birds from the north, and we welcome back members to the first general meeting of the season.  Our Speaker tonight is Mark Conboy, whose talk is entitled "The Sky is Green: a Brief Natural History of Guyana".

Sightings for the week (forgive us for being a bit late on the posting!) are in Peter Good's weekly report:

It has been a good week for fall migrants. Bald Eagles, both adults and immatures, appeared at four different locations this week. A Peregrine Falcon was on Amherst Island last Friday and Saturday. There has also been a good movement of warblers and vireos on a few of the days this week. Highlights included Philadelphia Vireos at Bedford Mills and Elginburg on the 4th and the 7th respectively, a Canada Warbler at Elginburg on the 3rd and 2 Connecticut Warblers, one out Montreal St. on the 3rd and the other at Elginburg on the 5th.
Incidental observations include a Chimney Swift on Queen St. on Wednesday, two Whip-poor-wills and a pair of Barred Owls calling at Bedford Mills, and a Great Horned Owl hooting near Camden East last night.
Shorebird sightings have been terrific. The Long-billed Dowitcher is still at the lagoons as was a Whimbrel last Thursday. There were two more Whimbel at the Kingston airport on Friday. The bar on Amherst has been very productive; last Friday a Hudsonian Godwit, a Willet, 2 Ruddy Turstones, a Red Knot and 8 Sanderling and then yesterday; a Stilt, a half dozen White-rumped along with a few Least and Semipalmated Sandpipers as well as 5 Short-billed Dowitchers , 7 Sanderling, a Black-bellied Plover, 3 Greater Yellowlegs and at least two dozen Semipalmated Plover.
