Fall Migration at TTPBRS: Oct 28 - Nov 3, 2006


Northern Saw-whet Owl (D.Derbyshire)

Fall 2006 is drawing to a close, as most of the landbirds have now passed through the area. However, birding is still good at Tommy Thompson Park as wintering birds arrive and late fall migrants trickle through. Northern Saw-whet Owls are still heading south through the Toronto area but in lower numbers than "normal". Due to weather, we have only been out on one occasion since the night of heavy migration on October 26. A total of 54 owls have been banded so far and 2 foreign banded birds have been recaptured.

The week of October 28-November 3 began with inclement weather, which limited our field coverage for the first two days. A full day's work on the 30th produced some interesting birds including observations of a Northern Shrike, 6 Snow Buntings, and good tallies of several waterfowl species. A fixture of late fall migration, the distinctive calls of Common Redpolls and Pine Siskins have been completely absent this fall. This is likely due to abundant cone crops in the north, which means that these species do not need to wander south for food. West winds continued on the 31st as 20 birds were banded from 5 hours of effort. The highlight of the day was our second ever capture of the maritime subspecies of Palm Warbler, the "Yellow" Palm Warbler. It was a chilly start on the 1st of November with temperatures hovering around 0 degrees Celsius. A total of 28 birds were banded on the day and a decent variety of late fall migrants were recorded. American Pipit, Cedar Waxwing, Slate-colored Junco and American Tree Sparrow were moving through despite the cold headwinds. November 2nd and 3rd were census-only days due to excessive wind chill.
