Another option is to use a consumer recorder like a Sony M10, etc, in MP3 m=
ode with an external battery pack to do long continuous recordings, and jus=
t throw away the bits you don't want. Depending on the bitrate, you should =
be able to get 10 days or more onto a 32GB card. I think a single pair of D=
 cells should last 4 or 5 days.=0D

The challenge is to weatherproof it enough. I put mine in a clip lock box t=
hat also holds the extra batteries, and the box sits inside a cooler bag fo=
r extra protection. I use external EM-172 microphones, that don't have much=
 protection other than a plastic lid held down with elastic. It's survived =
overnight downpours, but I try to avoid rain.=0D

Please let us know what you come up with, I'm interested to know about othe=
r possible solutions.=0D

Hi Andrew,=0D

Ultrasonic versions of what you describe are used extensively for bat resea=
rch and monitoring and there are ones designed for use in the audible frequ=
ency range as well. The Wildlife Acoustics Song Meter range should be suita=
ble for the kind of work you want to do: http://www.wildlifeacoustics.com/=

They're pretty expensive though - hopefully someone else on the group may k=
now of a cheaper option!=0D

All the best,=0D

Hi,=0D

I was wondering if the group has experience with remote sound recorders ana=
logous to camera traps that you can leave for about one month. I would want=
 to record nocturnal owls, bats, hyrax, bushbabies here in East Africa.  Ei=
ther one that can be triggered by sound or programmed to record a sound win=
dow of  say 2 hours per day to limit battery time. Does anyone have any rec=
ommendations?=0D
