Raptor Observations: Sharp-shinned hawks had a good flight for early September at this site, while all other species had a typical showing. The flight was at an unusually low altitude for the first half of the day with most birds passing not far above tree-top level. The flight normalized mid-day as birds took a pleasant line for viewing, running southeast to northwest over Gibraltar and just north of us. The first merlin of the season was seen. Non-raptor Observations: Notable feeding flocks of swallows were visible just south of the boat launch with barn, tree, and northern rough-winged identified. Purple martins were around all day, but in low numbers. Monarch migration amounted to fewer than 50 individuals, but was the most we have seen. Dragonfly activity was low with less than a few dozen seen all day. Two common nighthawks passed during the morning. Predictions: Tomorrow will be a bit warmer, peaking at about 84 F. Winds will be low from the southeast maintaining a consistent strength throughout the day. The flight will likely be similar to today. ======================================================================== Report submitted by Jonathan Stein ([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.
