Ospreys (Pandion haliaetus) are quintessential fish hunters that can be seen foraging over waterways across most of America, and indeed much of the world. Whether dutifully caring for their chicks at the nest or plunging into the water in a dramatic display of fishing prowess, these birds are a thrilling sight for any birdwatcher. So where do Ospreys live, and which habitats do they prefer?
Ospreys feed almost exclusively on fish and therefore spend most of their time near the water. Birdwatchers can see these expert hunters foraging over many different aquatic and marine environments, although they do not usually hunt far out to sea or in heavily vegetated swamp environments.
This general habitat requirement allows Ospreys to thrive on every continent except Antarctica, making them one of the most widespread birds of prey in the world.

Ospreys are partial migrants, which means some populations are sedentary while others migrate between summer breeding grounds in the northern hemisphere and their overwintering range in the south.
Their migrations can take them over 4000 miles (6400km) south, only to return to nest in the same tree or nesting platform every year.
This article covers the habitat and distribution of Ospreys. Read along to learn everything you need to know about where these majestic birds live.
The Osprey has an extensive distribution, occurring throughout much of North and South America, Europe, Africa, Asia, and Australia. Migrating Ospreys undertake impressive annual migrations that can cover several thousand miles.
Ospreys that breed in the Northeast of the United States, for example, will fly to tropical South America each year to enjoy warm weather and great fishing.
These long-distance flights make it possible to see Ospreys pretty much anywhere between their breeding and overwintering grounds.

Ospreys, or fish hawks as they are often known, are strongly associated with water. Read on to learn more about where Ospreys hunt, feed, sleep, and nest.
Ospreys are specialized fish hunters that hunt by plunging into the water and capturing fish at or just below the surface. They feed on several varieties of fish, including fresh and saltwater species that they catch with their sharp talons and the grippy scales that line the undersides of their feet.
This style of hunting means they are most successful when hunting over shallows or in areas where fish congregate at the surface of deeper water. They also prefer clear water with minimal floating or emergent vegetation.
Look out for Ospreys hunting in these areas:
Ospreys rarely forage out over the open ocean, although they have been recorded hunting surface schooling species like flying fish over 3 miles (5km) from the shore in West Africa. They will also readily hunt at artificial water bodies like reservoirs and dams, provided they are home to healthy fish populations.

Most Ospreys nest near their hunting grounds, although they sometimes nest as far as 12 miles (20km) from the water. These birds build their nests on trees or cliffs, and in modern times they have found artificial nesting platforms to work just as well as more traditional sites.
Ospreys prefer to sleep off the ground on the branches of large bare trees, although they will also sleep on artificial structures like channel markers. These birds will also roost on logs on the shoreline or even directly on the ground in cold weather.
Ospreys are not very common birds, although their current population is healthy. Their numbers have recovered well after being decimated in many parts of the world. Causes of these declines include hunting, egg collecting, and the use of pesticides like DDT.
Today Ospreys can be pretty easy to spot in the right habitat, even though they usually occur in low numbers. They are migratory in most parts of their distribution, however, so you're pretty unlikely to spot them in the northernmost parts of their range outside of their breeding season.
At this time, many Ospreys are thousands of miles away, enjoying warmer weather on a different continent!

Ospreys are diurnal birds. The males may spend 5 hours or more foraging when they have chicks to feed, so this is a great time to watch these birds hunt. They are most active in the early morning and late afternoon when fishing is most successful, although you can see Ospreys foraging at any time of day.
Most Ospreys are migratory, which means they fly between their overwintering grounds and breeding grounds twice a year. Ospreys that nest in the United States and the United Kingdom fly south for the winter, overwintering in South America and Africa respectively. They return to their summer breeding grounds in the spring to nest, where they will use the same nest site year after year.
Some Ospreys are resident, staying in the same general area throughout the year. This is the case in some parts of the USA with milder climates like Florida and California. Australian Ospreys are also sedentary, remaining in coastal areas around the continent for all four seasons.

Ospreys are sedentary in two regions of the conterminous United States. You can see these birds all through the year in resident populations from California to southern Oregon in the west, and from eastern Texas to Virginia in the south.
You can see Ospreys just about anywhere in the United States while they’re migrating to and from their summer breeding grounds. They breed in varying numbers in Alaska and each of the lower 48 states, although most breed in the Pacific Northwest, the northern parts of the West and Midwest, the Northeast, and the South.
Ospreys are widespread breeding visitors to Canada, although they are not present in the winter. They breed in virtually all of the Canadian provinces with the exception of Nunavut and the northern parts of Quebec and the Northwest Territories.

Ospreys can turn up in suitable habitats just about anywhere in the United Kingdom. Some of these birds are only passing through on their way to and from northern Europe, although over 200 pairs are known to breed in Scotland.
These wonderful birds were reintroduced to the English Lake District after a long absence and are now regular breeders there. Today they continue to expand their nesting range, with many breeding records reported from Wales in the southwest.
Ospreys in Australia are mostly restricted to coastal areas where they can be seen virtually all around the continent with the exception of Tasmania and Victoria in the south. They prefer coastal lakes, lagoons, and estuaries, although they do occasionally move inland up larger rivers.

Ospreys are most common in the Chesapeake bay (the largest estuary in the United States) during the spring and summer. In fact, the bay is home to the world's largest breeding population of Ospreys and may support as many as 20 percent of the species’ breeding pairs.
The best place to see Ospreys is at their nest sites during the spring and summer. The female spends most of her time on the nest during the breeding season, relying on her partner to provide all the food that she and her chicks need.
For those who don’t have nesting sites nearby, there are various online nest cams where you can watch these celebrity birds without even leaving home!

Many Ospreys migrate to the Southern hemisphere when it’s winter in the northern hemisphere. Not all migrating Ospreys will travel such long distances, however, with some birds merely moving a little closer to the equator. Many Ospreys from the United States, for example, spend the winter in South America, while pairs that nest in the UK and Europe head south for Western and Southern Africa.
Late Spring marks the start of the breeding season for Ospreys in the United States and the United Kingdom. By the summer, pairs will have returned to their breeding grounds as far north as Alaska and Scotland to raise a new generation. Ospreys are usually monogamous, with faithful pairs living and breeding in the vicinity of the same nest every summer.
