Well that is totally bizarre, because some friends of mine said they saw the GH 
Owls on that nest Saturday afternoon (I think) and I was there myself on Friday 
morning when the owls were definitely in residence.

What happened?

    The warbler team had a moderately good day. We did not find many migrants: 
one White-throated Sparrow as we were leaving the Lab and then a Yellow-bellied 
Sapsucker calling as we got into the cars. The swan pen at Stewart Park had few 
birds and the waterfront produced the more common waterfowl. An ornithology 
class from Binghamton did find a Ruddy Duck, which we missed. We heard and saw 
Fish Crow, at least 5 around the picnic tables near the band shelter.  We did 
hear the wheesey call and see glimpses of two Blue-gray Gnatcatchers along the 
west band of Fall Creek.


    We drove over to the golf course and first stopped to see the Great Horned 
Owl nest. To our total surprise, , although there was no owl in sight, there 
was a Red-tailed Hawk flat on the nest as if incubating. I know some species 
reuse the nest of other species, but two raptor species in the same season? If 
the red-tail is incubating, it must have started laying almost immediately 
after the GHOW left, because it was there just two weeks ago.


    Jetty Woods had ~30 cormorants distributed among two trees with a lot of 
guano beneath them, suggesting several days stay. We had a fine view of a 
flicker singing, if you call it that, and then later the same bird on the 
ground, apparently eating ants.


    Perhaps most enjoyably, we found a White-breasted Nuthatch pair carrying 
material into a cavity in the end of a large, broken branch along the south end 
of Jetty Woods. One bird actually removed some material from the nest, which 
reminded me of trying to move furniture to please my wife.


   A nice morning of birding.
