Hi Lance=20
I don't really see much difference. Since May 27, I have spent 9 early =
mornings (usually 30 min. before sunrise or from sunrise on) till about =
9-10 doing point counts and transect counts. I chose ideal mornings to =
count-little or no wind or precipitation. My gut feeling is that there =
is not a significant change from when I first started doing counts like =
this maybe 15 years ago. The odd point count can be quiet for some =
reason.=20
My first 3 min.stop at 4:38 on the James R. BBS route June 10 only had =
12 birds (6 species) but as the morning went on I would say 12-15 =
species would be average. Not sure how you define the dawn chorus- =
Certainly some birds start singing earlier than others with sparrows, =
thrushes and alder flycatchers being quite early. =20
Since you bring up bird song, I was a little stumped yesterday. I was =
searching dome boggy areas for butterflies after I finished the =
Trafalgar BBS route. There was a rather loud mostly single note repeated =
staccato song coming from a wet area with alders and Larch. The odd =
time it would end with a little trill on a different pitch. It is an =
area where Wilson Warblers (WIWA) have been know to breed just north of =
the Pictou-Guys border in Trafalgar. I wanted to see the songster with =
my eyes as I don't hear enough of these to get good at IDing by ear . It =
took a long time to finally see the bird-. The song carried quite far =
and I had to cross a cut-over with lots of dead wood left. I stood below =
the bird and it sang continuously above my head for 20 min. without me =
getting an eye on it. It did not respond to Sybley's WIWA from my =
I-pod. I tried to record the bird and play back, but the volume of the =
playback was too low. After I couple of tries I checked my microphone on =
the I-pod and it was crusted over so this was no use It would move from =
tree to tree from time-time, but still I could not see it. I thought to =
myself for a yellow bird it sure is hard to see. Finally I caught sight =
of it. I could not believe it was a Tennessee Warbler. It was dropping a =
good part of the normal song especially the beginning and most of the =
end. Sure fooled me, but glad to see what was actually singing. This =
area had dozens of Tennessee Warblers last year especially in an area =
where larch was showing evidence of damage from the Larch casebearer ( I =
think this was the cause). Interestingly the Larch recovered completely =
from the insect damage and there is no sign of any damage this year.=20
This was my first Tennessee Warbler for this year. There were very few =
reported outside the Trafalgar area last year. Anyone else hearing them? =
I often find that where they are, they are in numbers.=20
cheers

Subject: [NatureNS] Bird Song in NS
Hi everyone,
=20
I have been reading that some early indications are that there appears =
to be a marked decrease in the amount of bird song in some parts of =
northeastern North America; even going so far as to say there is no dawn =
chorus (excluding the tenacious robins of course). Certainly the cold =
and wet weather that much of the region has experienced has had a =
'dampening' effect on both singers and listeners. I'd be interested to =
hear whether people in various parts of the province have noticed any =
change from past years. It may be that these observations, which were =
made in the US, don't reflect what's happening with the birds that breed =
in NS but perhaps they do.
=20
Thanks for your input,
