Hi GeoffA good option for NFC recording is a 'bucket mic' type set up - li=
ke one of these ones pioneered by=A0Bill Evans. He has instructions on his =
website:=A0Old Bird 21c=A0- you can build your own or buy one from him.=A0T=
his mic samples a relatively good swath of sky for NFC recording - around a=
60 degree cone. i have used it to good effect in the US and in the UK. Thi=
s type of set-up is very popular in the States in NFC recording circles.=A0=
If you're interested in monitoring avian migration particularly you might =
want to join the Nocturnal Flight Calls Facebook group.=A0
