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.

Like all bats in the United States, [54] big brown bats can be affected by rabies. The incubation period for rabies in this species can exceed four weeks, [55] though the mean incubation period is 24 days. [54] Rabid big brown bats will bite each other, which is the primary method of transmission from individual to individual.

[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 ...
Bird migration is controlled primarily by day length, signalled by hormonal changes in the bird's body. [20] On migration, birds navigate using multiple senses. Many birds use a sun compass, requiring them to compensate for the sun's changing position with time of day. [21] Navigation involves the ability to detect magnetic fields.
