Where To Find Frogs In New York
Frogs live in many habitats across the state. Here are the best places to look.
- Woodland pools in early spring
- Marshes and swamps
- Ponds and lakes
- Streams and rivers
- Wet meadows and fields
- Gardens and backyards
Look near water at night with a flashlight. Frogs are most active after rain. Be quiet and patient, and you will see them.
Tips For Identifying Frogs
Here are some practical steps to help you identify frogs correctly.
- Look at size: Compare the frog to common objects. A bullfrog is as big as a fist, a spring peeper is smaller than a thumb.
- Check skin texture: Smooth skin means a true frog. Warty skin means a toad.
- Notice eye position: Tree frogs have large, bulging eyes. Spadefoots have vertical pupils.
- Look for markings: Spots, stripes, masks, and thigh patches are key clues.
- Listen for calls: Use the call guide above.
- Note the habitat: Wood frogs are in forests, bullfrogs in open water.
Take a photo or video for later reference. Many apps can help you identify frogs from pictures and sounds.
Common Mistakes In Frog Identification
Even experienced naturalists make errors. Here are some common mix-ups.
- Green Frog vs. Bullfrog: Green frogs have back ridges, bullfrogs do not.
- Leopard Frog vs. Pickerel Frog: Pickerel frogs have square spots and yellow thighs.
- American Toad vs. Fowler’s Toad: Count warts in spots. American toads have 1-2, Fowler’s have 3+.
- Gray Tree Frog vs. Green Tree Frog: Gray tree frogs have orange thigh patches, green tree frogs do not live in New York.
Take your time and check multiple features. One clue is not enough for a positive ID.
Seasonal Guide To Frog Activity
Frogs are most active in warmer months. Here is a month-by-month breakdown.
March To April
Wood frogs and spring peepers start calling first. They breed in temporary pools. Look for egg masses attached to twigs.
May To June
American toads, gray tree frogs, and green frogs become active. Leopard frogs and pickerel frogs breed in cooler water.
July To August
Bullfrogs and green frogs call throughout summer. Cricket frogs are active on warm nights. Tadpoles are everywhere.
September To October
Frogs prepare for winter. They eat more and find shelter. Some species, like wood frogs, can freeze and survive.
November To February
Most frogs hibernate. They burrow into mud or leaf litter. Do not disturb them during this time.
Conservation Status Of New York Frogs
Some frog species in New York are declining. Habitat loss, pollution, and disease are threats. Here is a quick overview.
- Common: American toad, green frog, bullfrog, spring peeper
- Uncommon: Northern cricket frog, eastern spadefoot
