Night Parrot captured and videoed

[Stephen Ambrose <>]

Hi Mike,

I think few researchers in Australia these days use harnesses that stay on
birds for a long time, unless one is studying long-distance migrants. The
type of harness I've seen used here is made from loose-fitting elasticated
straps that fray and eventually snap within a few weeks of being fitted.
But I realise that the older type of harness (which still seems to be used
in the northern hemisphere) does stay on longer and may potentially cause
the problems you mentioned.

Cheers,
Stephen

G'day All

Charles asked "Sean, do radio transmitters naturally fall off? I understand
from the 7.30 Report last night (10.08.2015) that the small battery lasts 21
days.

If the transmitter is attached using a harness, the harness remains for
months or years, possibly interfering with behaviour and moult.

If the transmitter is super-glued then it falls of in 2-4 weeks and the bird
is freed of any encumbrance.  When I used them on swifts I only ever
super-glued them - which is why my data ran out after 2 weeks each time.

Cheers

Mike
