Thank you all for brightening our day. Weather: Sunny, blue skies, high humidity, little cloud, light southerly winds. Raptor Observations: The expected Broad-winged Hawk migration did not occur at Holiday Beach today. A mere 12 Broad-winged Hawks followed yesterday's promise. Sharp-shinned Hawks continue to dominate the skies. The surprise of the day was the 8 Osprey, six of which were in rapid succession during a five minute period. Non-raptor Observations: Blue Jay migration started strong but fizzled at 2140. ======================================================================== Report submitted by Bob Hall-Brooks ([EMAIL PROTECTED]) Holiday Beach Migration Observatory information may be found at: http://hbmo.org/ Site Description: Holiday Beach Migration Observatory Information on southern Ontario's hawk migration and the Holiday Beach Conservation Area site ---------------------------------------------------------------------- Southwestern Ontario is largely an area of flat, featureless farmland. There are only two geographic features of note in the region. One is the proximity of the Great lakes, which influence bird migration in the area to a great extent, The second is the shape of the province, roughly funnel-shaped with the narrow end to the southwest. These features confine south-bound bird migrants, especially hawks, to specific flight corridors. Holiday Beach Conservation Area was formerly a Provincial Park, but is now administered by the Essex Region Conservation Authority (ERCA). It is strategically located at the extreme southwestern tip of southern Ontario. The park is on the eastern end of a large freshwater estuary known as Big Creek. (Specifically the site is 1.1 miles south of the junction Highway 20 (old 18) and Essex Road 50, Town of Amherstburg). The Holiday Beach Migration Observatory (HBMO) (founded in 1986) is a non-profit, volunteer organization formed to promote the study and protection of migrating birds. Activities focus primarily on fall migration of raptors and other species. This site is in Essex County, Ontario, on the north shore of Lake Erie near the Detroit River. In 1988, HBMO persuaded Detroit Edison to donate a 40 foot Hawk Tower which is now at the site. Southwestern Ontario has a funneling effect on migrating raptors due to the geography of the nearby lakes and the reluctance of most raptors to cross large bodies of water. Birds gain altitude over the flat farmland to the north and east, rising easily with the thermals that such areas provide in abundance. As the birds head south they meet Lake Erie and, reluctant to cross it , turn west. With appropriate wind and weather conditions, birds pile up along the lake shore and move west until they reach the narrow crossing at the Detroit River (or island hop within the river mouth).
