We only counted on 5 days this week, however, it was a pretty good week
with 1485 total raptors counted (mainly Red-tailed Hawks (961) and
Turkey Vultures (349)).. The best days were Wednesday, Oct. 22 with 862
total raptors including 499 Red-tailed Hawks and 260 Turkey Vultures and
Oct. 23 with 492 total raptors (356 Red-tailed Hawks). Based on the last
10 years of observation at High Park the following can be said about the
remainder of the season (More detail is available on the web at
http://www.torontobirding.ca/~gtrw/). Some species are pretty much
through their migration - Osprey, Broad-winged Hawk and American
Kestrel. Another group of raptors is nearing the end of their migration
- Turkey Vulture, Bald Eagle, Sharp-shinned Hawk, Northern Harrier and
Merlin. And a third group is entering the peak of migration - Northern
Goshawk, Red-shouldered Hawk, Red-tailed Hawk, Rough-legged Hawk and
Golden Eagle.

The following are our totals for the past week and year to date:

High Park Site Description

High Park is a 400 acre wooded park dominated by a Black Oak Savannah
located just west of Downtown Toronto near Keele and Bloor. The park is
operated by the City of Toronto Parks Department.


The Count site (Hawk Hill) is located on a small hillat the north end of
the Grenadier Restaurant parking lot. It is located about 1.5km (1 mile)
north of Lake Ontario, at an elevation of 110 metres above sea level and
38 metres above Lake Ontario. The site location is N 43 degrees 37
minutes 03.8 seconds, W 79 degrees 28 minutes 56.5 seconds. This station
is at the highest point and near the centre of the park; a steep slope
that descends to a large pond is immediately west of the station. Full
time counts have been recorded here since 1993.


The following are partners in our raptor migration monitoring in the
Greater Toronto Region: City of Toronto Parks and Culture Department,
Toronto Ornithological Club, and Local Naturalist's Clubs.
