Bird flu 'ruffles feathers' of cattle in Texas, Kansas, and New Mexico. Migratory birds can have an outsized impact on the human world as well. In March, it was reported by the United States ...
The Arctic tern has the longest migration journey of any bird: it flies from its Arctic breeding grounds to the Antarctic and back again each year, a distance of at least 19,000 km (12,000 mi), giving it two summers every year. [18] Bird migration is controlled primarily by day length, signalled by hormonal changes in the bird's body. [19]
The bats eat moths, beetles, dragonflies, flies, true bugs, wasps, and ants. They usually catch flying prey in flight. [15] Large numbers of Mexican free-tailed bats fly hundreds of meters above the ground in Texas to feed on migrating insects. [16] The consumption of insects by these bats can be quite significant. [17] [18]
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 ...

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.
The birds are noted for their fast, non-stop flying capabilities over huge distances. [6] They can fly up to 97 km/h (60 mph), with researchers finding little evidence of wind assistance. Some have been recorded to fly non-stop for 84 hours over 6,760 km (4,200 mi) at altitudes up to 8700 metres. [ 7 ]
Nighthawks prefer to nest in edge and early successional habitats, making them one of only a handful of birds which will live and hunt in burned or clearcut patches of forest. [15] The common nighthawk is drawn into urban built-up areas by insects. [5] The common nighthawk is the only nighthawk occurring over the majority of northern North America.
