Bat detectors for high frequency birds

[Mark Carter <>]

With reference to birders who have lost  their high frequency hearing range but 
still want to find emu-wrens or grasswrens I would suggest you try a simple 
heterodyne bat detector- they are directional, they function down to 10khz or 
less, you usually can record from them, they are cheaper than a hearing aid- 
but best of all they work on bats too! I've experimented with my Magenta 4 on 
Rufous-crowned and Southern Emu Wrens plus Striated Grasswrens with good 
results. 
For the time being you need to import these to Aus, but watch this space- I 
might import a batch later in the year.
