Mist netting for birds
Myself and Intern Tom (herpetologist in the making) set out
this morning at 4am to open up two mist nets we had set up yesterday evening in
some sandy scrubland next to the cerrado.
We chose a spot that was between two patches of bush with a
few trees, hoping to catch those that decided to flit between the bushes. The
sun began to rise at around 05:20, with a cup of tea in hand we sat and waited
out of sight for the 15 minute interval between checking the nets.
The nets had been previously used for catching bats, since
bats struggle when caught and chew the nets frantically- the nets were full of
holes and we were told not to be disappointed if we caught nothing.
To our surprise, on checking the nets we found 5 birds had
been caught in 1 net at the same time. We quickly got to removing them
carefully. The birds must be removed feet first, once the feet are free these
can be held onto and the rest of the bird untangled safely. The net is
incredibly fine and is sometimes hidden underneath the feathers so removing the
birds safely can be pretty tricky.We caught 3 spot-backed puffbirds (Nystalus maculatus) and 2
narrow-billed wood creepers (Lepidocolaptes angustirostris).
When caught in the net most birds relax and wait calmly to
be untangled. The puff birds were very
patient and easy to remove; one looked as though it had fallen asleep.The wood creepers however were less cooperative which made
taking measurements much harder.
After the first 5, we returned to our cold cups of tea and
waited for more birds but by 8:30am no more were caught and the morning window
of bird activity was over and so we headed back to base and put the kettle on.
