Hi
Years ago before I got hearing aids I used a Magenta Bat4 bat detector
precision with some success for Variegated Fairywrens. Battery operated and
small, range 15-130 kHz. You have to scan the kHz range and if it picks up it
makes a sound in the audible range with 2 pickups to assist direction finding.
Once you know the frequency you are looking for it is easier but not as good as
having someone with you that can hear them. Even good hearing aids do not help
me pick up wrens easily.
Cheers Chris

Subject: [Birding-Aus] Hearing the Striated Grass-wren
I have dipped on sighting the Striated Grass-wren and the Mallee Emu-wren on
each of my last three trips to Hattah-Kulkyne NP. I use the approach to finding
these birds suggested by Rohan Clarke and Tim Dolby, “walk slowly and quietly
while listening for their high-pitched calls.” I have spent days trawling
through ideal mallee spinifex habitat and heard not a squeak - deafening
silence. I would say my hearing is in the normal range for someone my age - 67.
Is there a readily affordable microphone that can pick up the high frequency
calls and ‘convert’ them into something I can hear? I imagine that people
interested in bats face a similar problem and are able to access equipment that
enables them to hear their calls.
Yours
