Spring Bird Migration in New York: When It Happens, What to Watch, and Where to Go
April 6, 2026
Every spring, something remarkable unfolds across New York — the sky fills with millions of birds pushing northward, painting parks, coastlines, and backyards with color and song. From the first American Woodcock probing the thawing ground in late February to the final wave of Blackpoll Warblers in late May, spring bird migration in New York is one of the most spectacular wildlife events on the East Coast.
Whether you’re a seasoned birder or just starting to notice the chorus outside your window, this guide walks you through everything you need to know — when migration happens, which birds pass through, where to watch them, and how to make your own yard a welcoming stopover for weary travelers.
Pro Tip: Spring migration in New York moves fast. The peak warbler window can be as short as two weeks — so the earlier you start planning, the better.
When Does Spring Bird Migration Happen in New York
In New York, spring migration spans March to June, with peak songbird migration occurring between mid-April and mid-May. That’s a broad window, but the action is anything but uniform across those months — each week brings a new wave of arrivals.
Although spring migration peaks in the first two weeks of May, northbound migrating birds pass through the park from early March until mid-June. The very first movers are the hardy early arrivals. The first migrant that typically puts in an appearance is the American Woodcock, which starts moving into breeding territory when there is still snow on the ground, with the first ones found in late February looking for softer patches of ground in which to feed.
By early April, the pace of migration lifts a little and the hardier warblers appear, including Pine Warblers and Yellow-rumped Warblers. Then, spring migration kicks into full gear in late April, with a host of new species putting in an appearance, with the Ovenbird being among the most numerous.
The second week of May is the height of spring migration. Spring migration is a little more compressed in time than fall migration, and all the birds are in full breeding plumage as they pass through, making identification a little easier — the males are often singing, too. This combination of vivid color and active song makes spring the definitive season for birdwatching in New York.
Key Insight: Birders in the Northeast and Upper Midwest may have to wait a few more weeks for peak migration compared to western states, according to BirdCast analysis that maps out the periods of highest aerial bird density across the United States from March to June.
Remember that most passerines migrate at night, whereas ducks, geese, and hawks migrate during the day. This means a great warbler morning often follows a calm, warm night — the birds have been flying overhead while you slept.
Which Flyway Runs Through New York
Each spring and fall, birdwatchers have the special opportunity to see hundreds of species of songbirds, shorebirds, birds of prey, and waterfowl that visit New York City, thanks to the state’s prime location along the area traditionally known as the Atlantic Flyway.
The Atlantic Flyway is one of four major migration corridors in North America. It stretches from Greenland and Nova Scotia in the north along the eastern coast of North America to the tropics of the Caribbean. New York sits squarely in the middle of this ancient aerial highway, making it one of the best-positioned states in the country for witnessing migration.
Millions of birds use flyways — or migration corridors — to migrate in order to avoid overpopulation in their breeding grounds and to find more abundant food supplies. The concept of a “flyway” is primarily a theoretical one, bringing together a geographic region of routes used differently by migratory species — the distance traveled along the flyway and specific routes taken vary by species and can vary by season.
New York City is situated directly in the Atlantic Flyway, and the city’s parks provide ideal spots for migratory birds to rest and refuel on their epic journeys. But the flyway’s influence extends well beyond the five boroughs — it shapes migration patterns throughout the Hudson Valley, the Adirondacks, Long Island, and the Finger Lakes region as well.
Key Insight: In the spring, sea ducks — especially scoters and gannets — will fly west to east along Long Island and Connecticut coastlines, adding a distinctive coastal dimension to New York’s migration experience that you won’t find inland.
The Atlantic Flyway also funnels an extraordinary diversity of species through New York. Millions of birds travel the Atlantic Flyway along the East Coast with the changing of the seasons. According to the Central Park Conservancy, 210 bird species can be found in Central Park alone, and the spring migration offers a chance to see them.
Which Birds Migrate Through New York in Spring
During the spring migration, which peaks in April and May in New York City, over 300 bird species can be observed stopping in some of the city’s green spaces. That number reflects the sheer diversity of the Atlantic Flyway — and gives you a sense of just how exciting a spring morning in a New York park can be.
Here’s a breakdown of the major groups you can expect to encounter:
| Bird Group | Notable Species | Peak Timing |
|---|---|---|
| Warblers | Yellow-rumped, Blackburnian, Black-throated Blue, Common Yellowthroat, Blackpoll | Late April – mid-May |
| Shorebirds | Red Knot, Semipalmated Sandpiper, Sanderling, Dunlin, Ruddy Turnstone | May – early June |
| Raptors | Osprey, Peregrine Falcon, Cooper’s Hawk, Sharp-shinned Hawk, Bald Eagle | March – May |
| Waterfowl | Ruddy Duck, Snow Goose, Tundra Swan, Canada Goose, Atlantic Brant | March – April |
| Songbirds | Scarlet Tanager, Baltimore Oriole, Indigo Bunting, Rose-breasted Grosbeak | Late April – May |
| Early Arrivals | American Woodcock, Fox Sparrow, Red-winged Blackbird, Tree Swallow | Late February – March |
Warblers are the rock stars of spring migration — 36 species of warblers can be spotted over the course of spring migration in Prospect Park alone. Known for their bright colors in spring, warblers are a group of energetic songbirds that migrate at night and rest and refuel by day. When warblers journey over Brooklyn, they are likely to stop in Prospect Park, where they feed on insects and berries.
Bright red might mean a Scarlet Tanager, vibrant orange could be a Baltimore Oriole, blues show up on Eastern Bluebirds and Indigo Buntings, and even year-round American Goldfinches wear their brightest spring yellow. You can learn more about some of these stunning arrivals in our guide to yellow birds in New York.
For shorebirds, the spectacle is equally dramatic. The Red Knot flies as far as 9,300 miles each spring and fall, between wintering grounds in Tierra del Fuego and nesting territory above the Arctic Circle. Along the way, it and other shorebird species such as Semipalmated Sandpipers, Sanderlings, Dunlin, and Ruddy Turnstones depend on stopping and refueling in New York City’s marshes, beaches, and mudflats.
Many raptors begin their trip north early in the season. In addition to year-round Red-tailed Hawk residents, look for Merlins, Cooper’s Hawks, Sharp-shinned Hawks, and more soaring above parks, perched on high vantage points. If you’re curious about one of the most exciting raptor visitors, check out our profile of the Merlin bird.
You might also encounter some of the largest birds in North America passing through, including Bald Eagles and Ospreys, particularly along the Hudson River and Jamaica Bay corridors.
What Triggers Migration and How Birds Navigate in New York
It’s one of nature’s great mysteries: how do birds know when and where to go? The answer involves a combination of internal biology, environmental cues, and remarkable sensory abilities.
Although the seasonal timing of migration is generally governed by the photoperiod — the day length — local variation in weather conditions can “bottle up” migrants for short periods, resulting in heavy days and light days at any given locality. In practical terms, this means a rainy, windy night can ground thousands of birds, and the morning after a clear, calm night can produce an extraordinary “fallout” of migrants in New York’s parks.
Birds coming from the tropics are returning to their breeding grounds, where the days are longer and there is a greater abundance of food and space. Breeding in the heat of the tropics brings a different set of challenges to the success of eggs and chicks. By migrating north, these species are moving to a more temperate climate to raise their delicate young.
There are many birds that are hardwired as to when to head north. Birds traveling from as far as South America or Costa Rica have no way of knowing what the weather is like in the United States, so a milder winter here will have no effect on their arrival. The more flexible species are those that winter in the US and have a shorter distance to travel to their breeding grounds — they may sense the milder temperatures and opt to head north sooner. This includes species like the Red-winged Blackbird, American Woodcock, and Tree Swallow.
Key Insight: Birds don’t necessarily migrate because of temperature changes. However, when it gets cold, a lot of their food sources disappear — insects die or hibernate, and trees stop producing leaves and berries, so migration is essentially a global search for food.
Once in the air, birds use a sophisticated suite of navigational tools. Topographical cues such as coastlines, river courses, and mountain ranges help to guide the journey. Astronomical and physical signposts — such as the stars, the sun, and the Earth’s magnetic field — also aid in steering migrating flocks toward their destinations.
Most songbirds migrate at night because the air is cooler, allowing them to fly farther without having to stop and cool down. However, this nocturnal travel creates real risks in a place like New York. Most migrating birds, especially songbird species, make their journeys at night. This can be especially risky when flying over big cities, where light pollution from bright, artificial light can throw birds off course and cause them to circle in confusion. Reflections from artificial light can also cause birds to collide with buildings.
An estimated 100,000 to 200,000 birds die colliding with buildings in New York City each year — a sobering reminder that even the most extraordinary navigators face man-made hazards. Campaigns like Lights Out New York have been created to dim bright building lights during migration season to provide safer passage for birds.

Best Spots to Watch Spring Bird Migration in New York
New York offers an incredible range of birding habitats — from urban parks to coastal marshes to forested ridges. Here are the top locations to experience spring migration firsthand.
Central Park, Manhattan
Located along the Atlantic Flyway, Central Park welcomes more than 210 bird species each year. Many live in the park year-round, with others making an important stop to rest and feed during spring and fall migrations. Boasting over 843 acres with 200 acres of dedicated woodlands, Central Park is easily accessible, large, and a hotspot for many migratory and permanent birds. The North Woods and the Ramble are two of the largest wooded areas in the park, offering gorgeous views of the flora and an opportunity to catch flecks of color in the greenery as birds dart from tree to tree.
Prospect Park, Brooklyn
With over 150 migratory species set to make an appearance in Brooklyn’s backyard, Prospect Park lies on one of the great flight paths of the natural world — the Atlantic Flyway. When warblers journey over Brooklyn, they are likely to stop in Prospect Park, where they feed on insects and berries. Rested and refueled, they continue on their way after a day or two.
Jamaica Bay Wildlife Refuge, Queens
In spring, ospreys flock to Jamaica Bay and ruby-throated hummingbirds feast among nectar-rich flowers. The salt marshes throughout the refuge offer stunning observations of migratory shorebirds and waterfowl, while the skies and trees hold soaring birds of prey or small, trilling groups of songbirds. This is one of the premier shorebird sites on the entire East Coast during spring migration.
Pelham Bay Park, the Bronx
Pelham Bay Park, the city’s largest park, houses beaches, miles of shoreline, and seemingly endless hiking trails. Some of the most sought-after birds can be found here — think owls, hawks, and the elusive American Woodcock. Pelham Bay is known for its notable bird residents year-round, but the spring migration is especially productive for birdwatching.
Smaller Parks and Neighborhood Spots
Walk around your neighborhood with new eyes and find your own local birding patches. In New York City, even the smallest parks can hold great surprises during migration season. You don’t need to travel far — a tree-lined street, a community garden, or a small waterway can all serve as critical stopover habitat during peak migration.
Pro Tip: The best times of day to go birding are early mornings and late afternoons, when birds are the most active. Aim to be at your chosen spot at or before sunrise during peak migration weeks in May.
How to Track Spring Migration in New York in Real Time
One of the most exciting developments in modern birding is the ability to follow migration as it happens — sometimes down to the hour. Several free tools make this possible, and they can dramatically improve your chances of being in the right place at the right time.
BirdCast
BirdCast uses weather radar to detect and predict the numbers and flight directions of migrating birds aloft to support bird conservation and expand understanding of migratory bird movement. You can explore live and historical migration data — including the number of birds in flight, altitude, and flight direction and speed — for any state or county in the contiguous U.S. BirdCast also provides a list of bird species you’re most likely to see at this time of the year.
The live data feed runs from March 1 to June 15 during spring migration and from August 1 to November 15 during fall migration. Check BirdCast.info the night before — their radar-based migration forecasts predict how many birds will be moving. When they show high intensity over your area, set your alarm early — it’s going to be a big morning.
eBird
eBird is among the world’s largest biodiversity-related science projects, an unparalleled resource with hundreds of thousands of users across the globe. Birders submit more than 100 million bird sightings annually, which eBird uses to spectacular effect. eBird’s free mobile app makes it easy to find good birding locations — “hotspots” — near you. If you’re interested in learning where and when specific species migrate throughout the year, eBird offers high-resolution animated migration maps that combine observational data with NASA satellite imagery to provide a week-by-week overview of migration.
Log your sightings on eBird. Your observations contribute to real science — researchers use eBird data to track migration timing, population trends, and habitat use. It’s free and takes just a few minutes.
Merlin Bird ID App
The Cornell Lab’s Merlin Bird ID app is an essential companion in the field. It can identify birds by photo, description, or even sound — just hold your phone up and let it listen to the birds around you. It’s free, regularly updated, and works offline, making it perfect for a morning in Central Park’s Ramble or along the Jamaica Bay shoreline.
Journey North
Journey North doesn’t offer the massive data set that eBird does, but it has unique migration maps. First-observation maps are available for orioles (Baltimore and Bullock’s), American Robins, Red-winged Blackbirds, and hummingbirds (Rufous and Ruby-throated), among other species. It’s a great tool for tracking the arrival of specific beloved species.
Important Note: Local variation in weather conditions can “bottle up” migrants for short periods, resulting in heavy days and light days at any given locality. Don’t be discouraged by a slow morning — the next clear night could bring a flood of new arrivals.
How to Make Your Yard Migration-Friendly in New York
You don’t have to go to a park to enjoy spring migration. With a few thoughtful adjustments, your own yard or balcony can become a valuable stopover for birds traveling through New York.
Food and Feeders
Many migrating songbirds won’t be tempted by regular seed or suet feeders — Gray Catbirds, Rose-breasted and Evening Grosbeaks among the delightful exceptions — as they are seeking insects and berries to eat after their long journeys. To attract the widest variety of migrants, focus on providing natural food sources rather than relying solely on feeders.
- Plant native berry-producing shrubs like serviceberry, elderberry, and dogwood
- Avoid pesticides — insects are critical protein for exhausted migrants
- Put out sliced oranges and grape jelly for Baltimore Orioles
- You may leave food out for seed-eating birds, provide nectar for hummingbirds, or sliced oranges for orioles.
- Offer mealworms for thrushes and bluebirds
For a deeper look at what different birds need to eat, our guide on what birds eat to survive is a great starting point. And if you’re looking to upgrade your setup, explore our overview of different types of bird feeders to find the right match for your yard.
Water
A clean, moving water source is arguably the single most powerful thing you can add to your yard for migrating birds. To attract birds on your own, it’s helpful to look for areas with diverse habitat, flowering trees varied in height, insects, and water. A simple dripper or small fountain added to a birdbath creates the sound and movement that draws migrants in from surprising distances — even in the middle of a city block.
Native Plants and Habitat
It’s helpful to look where there are food sources — areas with diverse habitat, flowering trees varied in height, insects, and water. Native plants are the cornerstone of a migration-friendly yard because they support the insect communities that fuel migrating birds. Even a small patch of native wildflowers or a single native tree can make a meaningful difference.
Window Safety
Glass-covered buildings present a collision hazard, as the reflection of open space in glass windows may confuse birds. You can make your own windows bird-friendly by installing bird-safe glass or adding temporary decals during migration periods. This is especially important during April and May when migration intensity is at its peak in New York.
Building managers and residents can also minimize their impact by turning off unnecessary outdoor or near-window lights at night, especially in the spring (April and May). Participating in the Lights Out New York initiative is one of the most impactful things you can do for migrating birds in an urban environment.
Common Mistake: Leaving outdoor lights on all night during April and May. Scientists have suggested that the bright lights of urban areas may be interfering with the navigation abilities of birds that use the position of stars to navigate. Switch off non-essential lights from dusk to dawn during peak migration.
Respect and Observation Ethics
Remember that these birds are under physical stress from their long migration, so avoid flushing or pushing them with your presence. View with binoculars from a comfortable distance and you may observe courtship behavior or the gathering of nesting material.
Limit the use of recordings and other audio methods of attracting birds, particularly in heavily birded areas. In popular New York City parks, out of both concern for the birds and mutual respect for fellow birders, it is recommended to refrain from playing bird recordings.
If you’re new to birdwatching and want to explore some of the species you might attract, our guides on birds that sing at night in New York and types of birds that are blue are great places to start building your identification skills. You might also enjoy comparing some of the lookalikes you’ll encounter, like the Bluebird vs. Blue Jay.
Spring bird migration in New York is a gift that arrives every year without fail — a reminder that the natural world operates on rhythms far older and grander than any city skyline. Whether you’re standing in the Ramble at sunrise, scanning Jamaica Bay at low tide, or simply watching your backyard birdbath from a kitchen window, you’re witnessing one of the greatest wildlife spectacles on Earth. Get outside, look up, and let the birds find you.
