New osprey translocation project for Poole Harbour, Dorset


A new and exciting Osprey translocation has been given the go ahead to take place in Poole Harbour this year as a first stage in establishing a south coast breeding population of this spectacular bird. The project is being led by local charity Birds of Poole Harbour, Scottish charity the Roy Dennis Wildlife Foundation and local Poole based-business Wildlife Windows.

Ospreys, which feed exclusively on fish, historically bred across the whole of Britain and NW Europe; but populations drastically declined in the Middle Ages and became extinct in England by the mid 1800’s. The five year project looks to restore Ospreys to their former breeding grounds in the south of England where they used to have the local nickname “Mullet Hawk”. At the same time the project will provide an important stepping stone between breeding populations in Britain and northern France, with the aim of enhancing the long term survival of the Western European population as a whole. The project is part of a wider conservation recovery plan of Osprey in Western Europe and the Mediterranean region.

A Conservation Recovery Plan
Ospreys are annual visitors to Poole Harbour as they pass through on their northward and southward migrations between their breeding grounds in Scotland and central England and their over-wintering grounds in West Africa. Over the last 8 years, efforts within Poole Harbour have been made by the RSPB, National Trust, Natural England, The Forestry Commission and private landowners to try and attract Osprey to stay and breed by erecting artificial nesting platforms in the hope that the birds will adopt them as their own nests. Osprey are semi-colonial and often choose to nest in areas where other Osprey are nesting and in 2009, the RSPB went as far as placing decoy birds, supplied by Roy Dennis, on one of their nesting platforms on their Arne Reserve. Although there has been some interest by Osprey in these nesting platforms over that 8 year period, none have decided to stay and breed and it’s now thought a translocation project is the next logical step to try and encourage these incredible birds of prey to settle on the south coast of England.

Previous Restoration Success
Translocation has proved a highly successful means by which to restore ospreys to areas from which they have been lost. The much-admired population at Rutland Water in the East Midlands was established by a pioneering translocation project in the late 1990s and similar work has since taken place in two regions of Spain as well as in Italy, Portugal and Switzerland.

This pan-European experience means that the Poole Harbour project, which will involve licensed collection of five-six week-old chicks from healthy, sustainable populations in Scotland, has the best-possible chance of success. Once collected the chicks will be safely brought down to Poole Harbour and held in large holding pens at a confidential site for just two – three weeks to acclimatize to their new home and prepare for their first flights. Once released they will be provided with fresh fish on artificial nests, to replicate normal osprey behavior, and so are likely to remain around Poole Harbour for a further six weeks (the normal post-fledging period) before beginning their long migration to West Africa. During this six week period the birds will imprint on the area and adopt Poole as their new home.

Paul Morton from the Birds of Poole Harbour charity stated:
The main issue that limits the natural spread of Ospreys is their natural dispersal. When young Ospreys return to breed for the first time, males prefer to nest in the area where they themselves were raised, while females tend to settle close to where other Ospreys are nesting. These factors combined mean that the natural expansion of the species is very slow – often as little as 11 km per year. This project will help to significantly speed up this process and restore the Osprey to the south coast where we know that they were once a common sight. The experience of other projects in Europe indicates that we should start seeing translocated Ospreys returning to their adopted home of Poole Harbour two-three years after they are released“.

Every autumn Poole Harbour can host up to six Osprey at any one time, attracted by the abundance of salt water fish such as Mullet, with the last two weeks of August and first two weeks of September being the optimum time to see them as they fatten up before their long journey south to West Africa.

Osprey tourism is hugely popular with the top four Osprey visitor attractions in the UK raising around £4 million each year for local economies between the months of March and August.

Paul Morton said, “We hope that this is a project that the whole community will get behind. In other parts of
the country there is great excitement when the Ospreys return each spring, and in years to come it would be
marvelous if there is a similar feeling in Poole and along other parts of the south coast.”

Roy Dennis and Tim Mackrill, from the Roy Dennis Wildlife Foundation, who have expertise in osprey translocation added, “This project is the next logical step in the conservation of Ospreys in the UK and Western Europe. The Rutland project completely changed the distribution of the species in the south of the UK, but they remain a very rare breeding bird in England despite the fact that extensive areas of suitable habitat exist. Establishing a population of Ospreys on the south coast, where estuaries provide extremely rich fishing grounds, will be another positive step forward and help to link existing populations in Rutland, Wales and France, as part of a pan-European recovery of the species.”

Jason Fathers of Wildlife Windows concluded, “It is a privilege to be involved in this significant project to restore Ospreys to their former breeding grounds in the south of the UK and even more rewarding to know that this step can help the European population as a whole. Much work has been done by local conservation organisations over the last eight years to persuade these wonderful birds to breed here once again and it is great to know we are one step closer to realizing this goal”.

    What great news! A fantastic addition to the south coast, this will really excite the local community especially kids – imagine if we’d had the chance to get involved with something like this at primary school?. Wonder if the opposition will post this up and say what a great thing it is and how fantastic BOPs are for bringing in tourist pounds – fat chance. Wish generally there was a bit more re trans locations to areas where there should be relatively little persecution – red kite, goshawk, pine marten and polecat would be good candidates, the more places they get to where there’s little sports shooting, the more the populations can build up in spite of the hammering they are still getting elsewhere. After decades of very slowing advancing from the highlands pine marten are now in the central belt and in spite of rather low reproductive rate are fairly racing through it – funny what happens when you get away from snares and tunnel traps. Seems there’s talk of a white stork reintroduction down south too.

      Yes it will be interesting to see if the tourism benefits are mentioned by the grouse brigade, or the apparent similarity with the benefits of the brood meddling project ( requires twisted logic ). Of course they will only make themselves look even more foolish that they already do, but I wouldn’t be surprised if they try.

    Fantastic news !
    Should have happened much sooner as there is room for dozens of pairs on the south coast & there is basically zero failure rate with Osprey reintroduction.
    Having reintroduced Goshawk to parts of the UK myself I can say that it is a remarkable feeling to see raptors that you have personally brought back, thriving where they were exterminated by gamekeepers.
    White tailed eagle, Red kite,Goshawk,Osprey ….we are turning the tide !
    When driven grouse shooting is finally stopped many years in the future, Hen harriers will once again recolonise the south of UK.

    Keep up the pressure !

    According to a Spanish friend who was involved in the introduction scheme there, Andalucia officially has 15 pairs of Osprey this year (although he knows of at least two more). Unlike the former Andalucian population, which bred along the coast, most of the current population nest on inland reservoirs that simply weren’t there 30-40 years ago. The wintering population of western Andalucia is now c100 birds and it’s now not unusual to find a couple of wintering birds in the Bahía de Cadiz, marshes of the Guadalquivir or nearby wetlands. Let’s hope that this scheme restores the species as a breeding bird in southern England.

    Delighted to see Roy is still heavily involved in these type of projects – the man is a legend.
