Weather: Cloud cover was low today, though we saw two very interesting cloud formations. One looked like a crown on a head, or an eye with intricate eyelashes. The other looked looked like a tornado. When the moon came above the horizon, it was magnified by the atmosphere to look very large. Barometric pressure dropped steadily all day, and was a quarter inch lower by the end of the day compared to the starting point. Winds always had a westerly component. Raptor Observations: The highlight of the day was two light morph Rough-legged Hawks that flew over together. We also saw an adult Golden Eagle, and a few low Northern Harriers. Otherwise, the main in-the-sky highlights were cloud formations, if that tells you anything. The winds may have directed many migrants to the north, and/or the dropping barometric pressure may have caused a sensation unimaginable to us which caused most birds not to migrate. No migrating raptors were spotted in the last two hours of the count. Non-raptor Observations: American Crows appear to be well-past peak migration, as we spotted only 8 today. A small flock of American Robins flew overhead. A single Double-crested Cormorant was spotted. Predictions: Tomorrow is predicted to be partly cloudy, with a strong north wind. This wind may push birds to the south, so Point Mouille may be a good alternative spot to check out. ======================================================================== Report submitted by Detroit River Hawk Watch (greg_norw...@fws.gov) 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.
