Bats in New York: identification guide and where to start looking

What are the most common bat species in New York?

New York hosts nine resident bat species. The big brown bat (*Eptesicus fuscus*) and little brown myotis (*Myotis lucifugus*) are the most widespread. You'll also encounter the eastern red bat (*Lasiurus borealis*), hoary bat (*Lasiurus cinereus*), and silver-haired bat (*Lasionycteris noctivagans*). Less common but present: the northern long-eared myotis, small-footed myotis, Indiana myotis, and eastern pipistrelle (tricolored bat). The big brown bat is stocky with a wingspan up to 13 inches, while the little brown bat is smaller, about 3-4 inches long. For more on bat diversity, see ourbat species hub.

How can I tell bats apart from birds in flight?

Bats have distinctive erratic, fluttery flight patterns, unlike the straight gliding of birds. Their wings appear long and narrow, with visible finger bones. At dusk, look for quick darting movements and frequent changes in direction. Bats also tend to fly lower than most birds, especially near water. If you hear high-pitched clicks (with a bat detector), that's a bat. Listen for the difference between the steady chirps of birds and the rapid, irregular sounds of bats.

Where in New York are bats most often seen?

Your best odds are near water: ponds, lakes, and rivers, where insects swarm. State parks like Letchworth, Allegany, and the Adirondacks have good bat activity. Urban areas also work: Central Park in NYC and the Buffalo waterfront are known for bat sightings. Bats roost in tree hollows, under bridges, in barns, and inside caves. Look for them emerging at sunset from known roosts. For specific locations, check ourNew York wildlife guide.

When is the best season to spot bats in New York?

Bats are most active from mid-May through September, when insects are abundant. They hibernate in winter, so sightings drop to zero by November. The peak time for viewing is June and July, when pups are learning to fly. Evening emergence starts about 20 minutes after sunset, and activity continues for a couple of hours. On warm nights with low wind, you'll see the most bats. For reliable viewing, plan a summer evening visit to a bat-friendly spot.

What are the key identification markers for New York bats?

Focus on size, ear shape, and fur color. Big brown bats: large (4-5 inch body), brown fur, broad nose. Little brown bats: smaller (2.5-4 inch), glossy brown, pointy ears. Eastern red bats: rusty red, with a frosted look, and they roost alone in trees. Hoary bats: large, grayish with white-tipped fur, giving a hoary appearance. Silver-haired bats: dark fur tipped with white, medium size. Use a bat detector or app to hear echolocation calls: big brown bats sound like a low, steady buzz, while little brown bats have a higher, faster pulse.

What should I do if I find a bat in my house?

First, stay calm. Bats are not aggressive. Open windows and doors to let it escape. Turn off lights to reduce confusion. If it doesn't leave, wear thick gloves and gently place a container over it, then slide a piece of cardboard underneath and release it outside. Never touch a bat with bare hands. If bitten, seek medical help immediately for rabies risk. For prevention, seal gaps in your attic or chimney. Check ourNew York wildlife encountersfor more guidance.

How do bats behave during the day?

Bats are nocturnal, so during the day they roost upside down in dark, protected places like caves, tree hollows, or attics. They enter a state of rest called torpor to conserve energy. In summer, females form maternity colonies to raise young. You might see bats flying during the day if they are disturbed or sick, but that's rare. If you see a bat on the ground during daylight, it may need help. Contact a local wildlife rehabilitator.
