Re: [nfc-l] Pine Siskin, E. Phoebe calls detected, Gaithersburg, MD 4/2/14

I should have listened to the calls on something better than my phone. I have 
been fooled by that Wood Duck call during the day, especially when given by a 
perched bird high in a tree :)  But the paper on siskins calling at night is 
real -- check out:  Wilson Journal of Ornithology 123(1):161–164, 2011.

I have received an alternate possibility for my presumed siskin call from Jay 
McGowan. He suggests its a male Wood Duck. I listened to and looked at a 
sonogram of a male Wood Duck recording at Xeno-canto (XC70558). Matches very 
well. Sonogram of Pine Siskin "zr" call has a different look.

That makes two new bird sounds for the day. Besides the male Wood Duck call, 
came across some Eastern Towhees in the field today and it was 1st time I think 
I have ever heard them make their buzzy call that's like a longer drawn out 
Lincolns/Swamp Sparrow call.

Thanks for the input.

So these are now well documented and perhaps not that unexpected.

The Phoebe doesn't surprise me either, as I have pretty regularly heard 
Empidonax flycatchers (Least, Alder, Willow), as well as Eastern Wood-Pewees in 
full song flying over at night later in spring, so why not a phoebe?

Wanted to say "NFCs detected" instead of "calls detected" in subject line but 
that may not be quite accurate. Last night (with southerly winds blowing for 
first time since middle of month), I picked up a Pine Siskin's "zre" call 
around 1 AM and 9 minutes later recorded a possible Pine Siskin "waaaeee" call. 
Assume it was passing over but not sure. There has been no Pine Siskin 
irruption down the east coast of US this year but if one was gonna stop at my 
feeders on way back north, this would be the time of year I would expect one. 
From Evan's and O'Brien Flight Call CD, get the impression 1 AM would be little 
early in night to pick up a siskin passing overhead.

Likewise, around 2:28 AM, recorded an Eastern Phoebe singing. Sounds like its 
possibly in flight, with calls coming nearer and than moving off. Hard to tell 
for sure. There was an Eastern Phoebe singing from trees in my backyard around 
6 PM eastern time today. Again, referencing Evans and O'Brien, not much support 
for Eastern Phoebe singing in flight.

NFC recording sure does produce a lot of mysteries.

if interested, attached the Pine Siskin "zre" call and Eastern Phoebe 
singing recordings below.
