Generally quite with no rarities. 5 AMERICAN WHITE PELICANS flying over Shady Oaks Park were interesting. Largest numbers were for WHITE-CROWNED SPARROWs with couple of flocks of 30-40 birds, and EUROPEAN STARLINGs. Nice selection of raptors - BLACK-WINGED KITEs (2), RED-TAILED HAWKS, RED-SHOULDERED HAWK (1), SHARP-SHINNED HAWK (1), MERLIN (2), AMERICAN KESTREL, and OSPREY (2). Large I drove around Piercey Road which looked interesting on the map but the area is rapidly being developed with new roads, office complexes. Not much seen there. The reason for this note is a question on determining the gender for an Osprey. The Nat Geo guide talks about the bib on the neck as indicative of a female bird. Sibley does not make that distinction. Further the following article from Hawk Watch International seems to suggest that gender can't safely be id'ed in the field http://www.hawkwatch.org/RaptorWatch/Fall%202001/Pitfalls%20in%20Osprey% 20Identification.htm especially based on the bib. Are there other gender id. points to use other than the bib? Thanks, Vivek Tiwari [[email protected]] _______________________________________________ Do not post admin requests to the list.
