Spring 2017 could see the return of osprey fledglings from previous years

Young ospreys will often not return from their first migration until they are around 2 years old. May this year be the first time we see a Foulshaw Moss fledgling return?

Juvenile ospreys will often leave their wintering grounds in the warmer climes later than the adult birds.

The youngsters may reach the nesting grounds in the UK as late as June, too late to breed that year, but they may show interest in nests and may even try to take over nest sites, interfering with breeding pairs, as they search for nesting sites of their own.

Ospreys do not usually begin to breed until they are 3 to 5 years old. A pair will often spend their first year together building a nest and establishing a territory ready to return and breed the following year.

Ospreys, especially the males, will often return to the area in which they fledged to breed so keep your eyes peeled for the possible return of Blue 5A, Blue 6A, and Blue 7A our 2014 fledglings this osprey season.
