The average bird meal consisted of 90.8% honey bees and 9.2% beetles. [28] Predation is more likely when the bees are queening or during the peak of migration, from late March till mid-April, and in mid-September. Hives close to or under trees or overhead cables are at increased risk as the birds pounce on flying insects from these perches. [29]
Bats can eat up to 1,000 insects per hour, and they work as pollinators while the bees sleep. Move over, bees. How bats step in as nature's 'third-shift' pollinators
[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 ...
Animal migration is the relatively long-distance movement of individual animals, usually on a seasonal basis. It is the most common form of migration in ecology. [5] It is found in all major animal groups, including birds, [6] mammals, [7] fish, [8] [9] reptiles, [10] amphibians, insects, [11] and crustaceans.
"80% of our migratory birds here in North America are actually migrating at night," he said. "A large impact that humans actually have on birds during migration is with the light that we produce ...
To lose so many birds in a preventable way can cause serious problems for not only the bird populations and species themselves, but also for insects, plants and the larger ecosystem.

Birds (flying, soaring) – Most of the approximately 10,000 living species can fly (flightless birds are the exception). Bird flight is one of the most studied forms of aerial locomotion in animals. See List of soaring birds for birds that can soar as well as fly. Townsends's big-eared bat, (Corynorhinus townsendii) displaying the "hand wing"
