These birds have very short legs and never settle voluntarily on the ground, perching instead only on vertical surfaces.
It is, therefore, slightly odd to feel the mantle of responsibility, even if it is only diminished responsibility, perching itself rather warily on my shoulders at the present time.
In addition, we estimated the size of 18 territories, in situations of high and low resource density, by determining the perching sites and foraging area of each individual.
Raptors were seen soaring above the roost, perching on trees close to roosting animals, chasing the bats on the wing and diving into the roosting trees.
Axis 1 mostly represents food substrate and foraging technique variation, while axis 2 arranges species across a gradient of increasing perching height and perching site size.
To do this, we simply estimated the proportion of the 5-min periods that females spent engaged in three mutually exclusive behaviours: flying, perching and ovipositing.
Do perching structures elevate seed rain and seedling establishment in abandoned tropical pastures?
Traps were protected from perching birds by inserting nails around the frame.
