Re: [nfc-l] Mystery Calls

2017-05-03 Thread Laura Gooch
Jay's suggestion is a good one, when possible given how folks are making 
recordings. One note to Ken and others: I almost always listen to NFCs at 
quarter speed, with a filter on so that I only hear the frequency range of the 
call (and not the low frequency stuff that would blast my ears at quarter 
speed). I can hear the calls a full speed, but I can't differentiate them very 
well full speed. Slowing them down makes the distinctions clearer.

 Thank you Jay. I cannot hear most of the clips posted here. This is apparently 
a "thing" where some people can hear the bird sounds in these short clips and 
others cannot. I just hear a burst of static. Please put enough ambient sound 
on BOTH sides of the bird sound for our ears to hear the sound in its proper 
context. 
Thanks

Hi Preston,

Lesser Yellowlegs is possible but the other suggestions made so far are good 
too. Perhaps as you originally wondered, they are overlapping calls of two 
birds of a different species.

Hi Preston,

Very interesting flight call. It reminds me of a type 2 Red Crossbill. It’s 
sounds a bit soft for this species but distance from mic might cause that. It 
is also unusual to get just one or two notes. Were there any others? I see from 
eBird there are some recent records from MA, RI, and NJ.

Last night, I recorded some interesting calls - the first one sounding similar 
to northern cardinal. Do these calls originate from two separate species of 
birds, or are they one? And which species? Thank you.

Jay,

If we are using software to detect calls, then those recordings are in 
milliseconds. For example, my White-throated Sparrow call is just 0.34 ms, but 
occasionally it is longer. So at least I can't post  anything that is four 
second long. I too have the same problem of trying to listen. But I depend on 
the spectrogram to tell me what it is.  At least I don't record the whole night 
everything sound. I use Bill Evans' Tseep and Thrush detectors.  But now a days 
I am getting used these short bursts to some extent.

I am attaching a sample.

Hey all,
I've posted this before, but I would implore folks posting example recordings 
to this list to leave a few seconds of sound before and after the call in 
question so you can actually hear it. With only a second-long recording, all I 
hear is a burst of sound with no time for my ear to acclimate to the background 
noise. The same goes for audio upload to eBird. We suggest leaving three 
seconds, if possible, before the first and after the last vocalization in the 
recording before upload.

Thanks!

Hi Preston,

Very interesting flight call. It reminds me of a type 2 Red Crossbill. It’s 
sounds a bit soft for this species but distance from mic might cause that. It 
is also unusual to get just one or two notes. Were there any others? I see from
