Re: [nfc-l] Canada/Cackling Goose ID request, Solvang, CA (USA)

2019-10-03 Thread David Irons 
These sound like Greater White-fronteds, perhaps some feral Anser geese that 
are non-native. They are definitely not Cackling Geese.

Last Saturday night (2019-09-28, at about 1AM) I recorded several flocks of 
geese flying over my backyard in Solvang, California (USA). I would expect 
these to be Canada Goose, but they don't sound right for that (too high, no 
honking). So now I'm wondering if these are in fact Cackling Goose, which would 
be interesting given the size of the flock. Here is my best recording:

https://www.xeno-canto.org/500506

Does anybody have any suggestions what these are, and why? Probably (hopefully) 
we have to get to the subspecies level to sort this out. The original .WAV file 
is 7MB and I'll be happy to email it to those interested.

Thanks

Could you post a PDF of your fine article in Birding, gasp, 16 years ago?

calls with birds (netting, night time visual observations, etc)?

Imagine somebody trying to get into NFCs in an unexplored part of the
world. How does such a person start?
