Weather: Today began with almost no clouds, and therefore a glaring view due to the rising sun. Cloud cover gradually increased, and at around noon the 5-15 km/hour wind shifted from northerly and easterly to southerly and easterly. Raptor Observations: The British.. I mean Broad-wings, are coming! The Broad-wings are coming! Due to the more favorable winds today, we had our best Broad-winged Hawk day yet, with well over 2,500 birds counted. We spotted several prominent kettles, and had fun trying to count the hawks as they streamed down from high above out of one rising column of air to another. Sharp-shinned Hawks were trickling in all day, as were American Kestrels after 10 o'clock (at which point the Broad-wings also started to appear). Several Northern Harriers were also spotted. Non-raptor Observations: A couple large groups of American White Pelicans flew by today, with approximately 50 individuals in the bigger group. Interestingly, in addition to flying together, these birds will also hunt (fish) cooperatively. We also spotted the first migrating American Crow of the season. Predictions: Tomorrow is predicted to be mostly clear and sunny, with east and south winds by 10, so the Buteos may be soaring. ======================================================================== Report submitted by Detroit River Hawk Watch ([email protected]) Detroit River Hawk Watch information may be found at: http://www.drhawkwatch.org _______________________________________________ ONTBIRDS is presented by the Ontario Field Ornithologists (OFO) - the provincial birding organization.
