Rarely, they will come to the ground to eat insects. They usually fly relatively high, so, contrary to popular opinion, mosquitoes do not form a large part of their diet. [ 3 ] Research published in 2015, however, does indicate that the purple martin feeds on invasive fire ants ( Solenopsis invicta ) and that they may make up a significant ...
A technology suitable for small birds which cannot carry the heavier devices is the geolocator which logs the light level as the bird flies, for analysis on recapture. [45] There is scope for further development of systems able to track small animals globally. [46] Radio-tracking tags can be fitted to insects, including dragonflies and bees. [47]

Domesticating the birds and training them for the bead-catching game may take four to five months, Xie said. Players teach the birds to fetch by first throwing seeds into the air, and later ...
Many birds migrate in flocks. For larger birds, it is assumed that flying in flocks reduces energy costs. The V formation is often supposed to boost the efficiency and range of flying birds, particularly over long migratory routes. All the birds except the first fly in the upwash from one of the wingtip vortices of the bird ahead.
A big brown bat, eating a mealworm. Big brown bats are insectivorous, eating many kinds of insects including beetles, flies, stone flies, mayflies, true bugs, net-winged insects, scorpionflies, caddisflies, and cockroaches. [33] [32] It will forage in cities around street lamps. As the big brown bat is such a widespread species, it has regional ...

This can make the bird a nuisance when it chooses to roost in populated urban spots ...
