Hi Wim

I am in an unexplored part of the world – Mozambique – doing NFC recording and 
indeed it is very hard.  Some birds do seem to make daytime type calls but I 
have dozens of calls which I just don’t have a clue.  I think most of them are 
herons, ibises and rallids – which have been on the move recently – but some I 
cant even place to family.  All the more difficult are the range of calls of 
bats, cats, dogs and the noises that seem to be man made to cloud the 
interpretations too.  I have shared a few calls but it is even harder for 
someone who doesn’t know the local avifauna to advise.  Something as simple as 
what would seem to be an obvious Moorhen could be Lesser Moorhen or indeed a 
bunch of little known other rallids.  Baiilon’s Crake has recently arrived in 
local wetlands in unprecedented numbers, for instance, a species that I would 
have previously excluded as almost impossible and makes a huge range of 
vocalisations (some that sound like a Moorhen!).

So it is tough and any guidance from the group would be most welcome.

Subject: [nfc-l] How do we know NFCs?

So as I'm starting to learn about NFCs the obvious question came to
me: how do we know what we currently know?

Do we typically infer ID features from daytime flight calls where we
can visually verify our IDs? Or are night calls too different from
daytime ones, meaning that we have/had to find other ways of matching
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?
