Tweeters,

I believe that there was a study done on why some Prairie Chickens (not
sure which species or subspecies was studied but I believe it was Attwaters
which could be seen on their leks in the fall) would put on a Fall Booming
display. I believe, if memory serves me correctly, the conclusion that they
came up with was that the fall booming time correlated with the length of
the day of the spring booming time. It would be abbreviated display because
the days would continue to get shorter and cooler thus cutting short the
displays.

Take care,

Hi Tweets,

This fall, like others in the past, I've noticed what sounds like partial
spring song from Song Sparrows, and Robins. These observations have led me
to speculate that there may be a relationship between the time of year and
the availability of light that perhaps stimulates a hormonal response much
like the one birds experience in the spring. The light we're experiencing
now is comparable to mid/late March, right? Any experts out there care to
chime in on this? It is rather startling to see the leaves changing and then
hear a Song Sparrow up and singing for all he's worth...but only getting
part of the song.

On another note (arrgh), today at noon, I had a Merlin on the wing in
downtown Bellingham. On Monday at the same time of day, I watched a female
adult Peregrine perch up on the relay tower that sits on top of the US West
building on Forest St.. She sat there preening for the better part of an
hour. I'm guessing this is the same falcon I saw six weeks ago flying right
up Holly St., the main drag in town.

Good birding,
