Recording in central Michigan, my calls were peaking at about 4:00 AM-right
by the shores of Lake Huron.  My guess is that is when they are flying low
and looking to land.  I'd have to look at my old data, but I think my inland
recorders (not near woodlots) did not see the same peak.  Fall and spring
were very different as well.

Subject: [nfc-l] Intersting pattern in data recording

 

Hi all, 

I have been recording in Ithaca NY for last few days. I am finding an
interesting pattern in number of calls recorded per hour (between 9.00 pm to
5.30 am). My recordings of the calls peak around 3.00 am in the morning. So
I am not sure why that pattern. Whether that is the time when they are ready
to touch down so they fly low in search of good locations or something else
is happening? I am curious to know how others are finding. If any Ithaca
recorders are out there have you looked at the pattern? Bill Evans who has
been recording form Danby area in Ithaca sent me a pattern for one day and
that day it peaked around 1.00 am and it also at higher elevation of 1500
ft, while I am at at 821 feet. 

 

Here is the actual data.

 

 



 

Any thoughts are welcome!

Hi Preston and all,

I downloaded the calls you sent. The first one is a "double-up" warbler
mostly likely one in the genus Oreothlypis (Nashville, Tennessee, and
Orange-crowned). I would lean toward Tennessee for this one due to the nice
bend in the spectrogram. When I first looked at the second call, I thought
it was a Magnolia Warbler due to the spacing between humps, but on closer
examination its high frequency, number of humps, depth between humps, and
somewhat descending character fit better with Cape May Warbler.

Night of 9/01-02/16; Westport, Connecticut

 

I recorded an interesting call that night (the night of a small cold front),
and was wondering if anyone could aid me in its identification. Thank you
for any input.
