Folks
�
Let me go out on a limb � this is a birding listserve .�� This
could be a very good winter finch season since the drought was quite extensive
covering much of North America.�
�
I would not be surprised if we see Pine Grosbeak this winter in western
Maryland, as well as Evening Grosbeak dispersed around the state.� I don�t
want to go that far out on the limb and say look for Boreal Owls yet.� I
need to learn more about the Saw Whet movement.� My reasoning is because my
acorn fruit has fallen early, and much of it is very small, or has no meat as
all.� If this is the situation in large parts of the normal wintering range
of these finches � crossbills, grosbeaks, etc. � we may see the largest invasion
ever.� Birds need to eat and will look for the food while moving further
out of their normal wintering range.

Don�t hold your breath, but keep your eyes and ears open.� Learn the
flight calls if you can, learn and bird preferred food sources, and study the
plumages .
�
I have already had a Red-breasted Nuthatch, and a Purple Finch was calling
around the house yesterday.� I normally get a small flight of Purple
Finches in November.
�
Good birding.

Subject: [MDBirding] Governor Bridge Red Crossbill follow
up
� Hi
everyone,
I just wanted to pass along some additional information about
the Red Crossbill at Governor Bridge Natural Area in Prince George's
County.� I sent the recording off and heard back from Matt Young at
Cornell, he said the bird sounded perfect for a Type 3 Red Crossbill.� Matt
also mentioned that there are only a few recordings of type 3's from south of
Pennsylvania and they came from the finch super-flight of 1997-98.� I was
able to make a spectrogram and actually got some nice results (despite the poor
recording!) showing the typical type 3 call.� If Red Crossbills do become
more regular in the coming months, and I hope they do, it would be great to try
and get recordings of them so we can document the types involved; as you can
hear from my recording, even the really bad ones can contain valuable
information.� One thing that I have tried to remember is to have my
recording app on any time I am in the field, if I had done this when the
crossbill flew over the other day, I would not have had to wait for it to boot
up, and could have gotten much better recordings.
