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 ]
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]
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 ...
[34] [35] However most bird migration is in the range of 150 to 600 m (490–2,000 ft). Bird strike Aviation records from the United States show most collisions occur below 600 m (2,000 ft) and almost none above 1,800 m (5,900 ft). [36] Bird migration is not limited to birds that can fly. Most species of penguin (Spheniscidae) migrate by ...

Most accipitrids will not eat plant material. Insects are taken exclusively by around 12 species, in great numbers by 44 additional species, and opportunistically by a great many others. [23] The diet of the honey-buzzards includes not only the adults and young of social insects such as wasps and bees, but the honey and combs from their nests. [34]
A few days before Halloween, data collectors at the Jekyll Island Banding Station (JIBS) observe a steady, yet predictable, decline of birds in nets, signaling the end of migration.
The Migratory Bird Treaty Act of 1918 (MBTA), codified at 16 U.S.C. §§ 703–712 (although §709 is omitted), is a United States federal law, first enacted in 1918 to implement the convention for the protection of migratory birds between the United States and Canada. [1]
