Spotting Eagles and Ospreys in Poole Harbour

If you’ve ever dreamed of seeing sea eagles soaring over the coast or ospreys plunging into the water for fish, you don’t need to head to Scotland, Poole Harbour is becoming one of the UK’s best places to spot them, thanks to a dedicated conservation team. The 2025 season sees the hatching and fledging of our first white tailed single male chick from a pairing at Poole harbour.  

The Return of the Osprey

Ospreys were once widespread across Britain, but by the early 1900s they had vanished due to persecution. Slowly, they began to return, first in Scotland, and now — thanks to a dedicated reintroduction project — in Dorset.
Since 2017, young ospreys have been released into Poole Harbour to establish a new breeding population. In recent years, some of these birds have returned from their long migrations to West Africa, raising hopes that nesting pairs will soon become a regular sight here. Watching an osprey hover, then dive with talons outstretched to snatch a mullet or flounder, is one of nature’s great spectacles.

The White-Tailed Eagle Comeback

Even larger than the osprey, the white-tailed eagle is Britain’s biggest bird of prey, with a wingspan of up to 2.5 metres. Once common along our coasts, it too was hunted to extinction in England more than 200 years ago.
In 2019, a reintroduction project on the Isle of Wight began releasing young eagles. These birds wander widely, and Poole Harbour — with its vast shallow waters and rich feeding grounds — has quickly become one of their favourite haunts. They are sometimes seen perched on harbour islands or gliding over the estuary, scattering flocks of ducks and gulls in their wake.

A Harbour Big Enough for Both

Although the two species overlap, they each play a different role. Ospreys are fishing specialists, sleek and agile, while white-tailed eagles are opportunists, often stealing a catch or scavenging. In the grand pecking order, the eagle is top, but the harbour is abundant enough to support both.

How to See Them

One of the best ways to watch ospreys and eagles is from the water itself. Local operators run birdwatching cruises and safaris from Poole Quay, Wareham, and Arne. These trips often include knowledgeable guides who point out not just the raptors, but also avocets, curlews, and the winter flocks of wigeon and teal.
• Osprey cruises run particularly in spring and autumn, timed with their migration.
• Winter safaris are wonderful for spotting white-tailed eagles alongside vast gatherings of waders and wildfowl.
• From land, Arne RSPB Reserve and the Studland Peninsula are excellent vantage points.

A Seasonal Spectacle

• Spring and Autumn – prime time for osprey passage.
• Summer – osprey project birds hunting and terns nesting.
• Winter – best for seeing white-tailed eagles, plus huge flocks of avocets and ducks.
✨ From Ailwood Farmstay, it’s just a short drive to the quayside at Wareham or Poole for a birdwatching cruise, or to Arne for a land-based walk. Pack binoculars, a flask of tea, and be ready for that heart-stopping moment when a great winged shadow sweeps across the water.
