Marie 06/28/04 09:40 am I thought I would share some interesting info on our Ospreys.
It appears that Ospreys have to be three years old before they breed. Generally during their first summer osprey yearlings stay on their wintering grounds. Two year olds migrate close to their old nest sites roughly one month after the adults have left to head north to breed.Two year olds arriving one month later on the breeding grounds have no time to breed that year so go about building new nests for the following breeding season. Apparently six out of ten generally build their nests within 100km of their hatching nests. Once an osprey has built its nest it will return to it year after year. Now I know why the nest up at the Universtiy of Victoria isn't active this year. It must be a two year old's beginning nest and it is a beautiful looking one. another nest to watch nest year.

No we had a young female osprey who did not seem to have read any osprey books. She was only two years old and last year successfully raised two chicks.

Sadly she did not return this year.

As for where they establish their nests. Well the male stick quite close to where they fledged. Females on the other hand wander quite a bit.
