Sunday 24th March

Male osprey seen flying in vicinity of nest around 3.15pm. He lands on a branch adjacent to the nest where staff are able to ID him as last year's unringed male (Laddie)

Monday 25th March

Four osprey seen in vicinity and two female ospreys visit the nest, one of which bears a striking resemblance to Lady. She returns to the nest frequently and Laddie is not quite sure what to make of the situation. Half-hearted and unsuccessful mating attempts and much mantling follow

Laddie appears to be accepting this new female. He is bringing in fish and successful matings are now being observed
