Ospreys are monogamous and are strongly faithful to their nest and their mate. They tend to build their eyries on top of large conifers. The nest is large and made of branches and twigs and lined with small twigs, moss, bark and grass. It takes both birds 2-3 weeks to build is usually around 1.2 – 1.5m high and 0.5m deep, but with the addition of extra material over the years this can increase. The female will lay 2 or 3 eggs at the middle to end of April which she will incubate for 37 days. As with other raptors, the chicks usually hatch a few days apart. Nesting duties are clearly divided: the female carries out incubating, brooding and direct feeding of the young and guards them throughout nesting; the male is the major provider of fish for the female and their young. The chicks will fledge at 53 days and both parents will feed them. They stay close to the nest for another 2 months. Many juvenile birds die before they are 3, while the average life span of an Osprey is around 8 years – the oldest known Osprey, however, lived for over 30 years.
Well,thats not helpful either but if this nest was previously unoccupied there may be (are) several fmales laying claim to it.
"It mine".."No its mine" and so on until the supposedly stronger,older Osprey claims this nest as hers..
I do wish they would make up their minds.
Urmas,thank you for the info about the injury. If he was more busy he may forget about his scratches ?
