Beware, Jan, that the two sexes of sharp-shinned hawks are so different in
sizes that it would be easy to think you had two different species. Female=
s
are very large compared with males, which aren't much bigger than blue jays=
.
Merlins, on the other hand, likewise show sexual differences in size, but
nowhere near as much as the sharpies. Beware, too, of the confounding but
rare? possibility that a very big sharpie might be a Cooper's hawk.... and
then there are two sizes of Cooper's .... and then the same thing for
goshawks ..... YIPE! At the University of Alberta where I used to work
before Acadia Univ., there was a large collection of study skins of sharpie=
s
plus Cooper's plus goshawks, and the way they intergraded by size was tru;l=
y
scary for this birder!
Cheers?? from Jim in Wolfville

we have a small flock of wax wings as well,...attracted to ripe mountain as=

were attracted by the flutter of so many wings as there were also numerous
robins, sparrows, chickadees, finches, juncos, jays and doves.

When the feeders are this busy the predators aren't far behind. We've
had sharp-shinned hawks but these were quite a bit larger and the plumage
was all wrong. The tails seemed a bit longer too! I've never had a juvenil=

sharpie in my yard before and the pictures in my Sibley's show a bird much
more brown than the predominantly grey to grey/brown and speckley fellows w=

saw here yesterday. Can anyone offer suggestion as to an I D. They were
slender and slim winged, light underside, short face/beak.

They were so incredibly fast, as the waxwing fled the mountain ash the
hawk took him right out of the air. Later they were climbing an diving
straight into the thicket to the north of my house. Then circled, so fast t=

the south and disappeared...

As of yesterday, Glenys Gibson reports that the CAROLINA WREN was still

Sept. 29 and Oct. 1.
