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.

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.
[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 ...

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.
Silver-haired bats consume primarily soft-bodied insects, such as moths, but will also take spiders and harvestmen. This species will forage low, over both still and running water, and also in forest openings. Silver-haired bats are slow but maneuverable flyers that typically detect prey a short distance away. [10]
Bats' biggest boon to humans may be in their diet. A single bat can eat thousands of insects per night, ridding the air of mosquitoes and other pests. Bats may be a scary Halloween symbol, but ...
