Saturday 11th April

Blue 5F visits again whilst the nest is empty. Glaslyn female soon returns and escorts her away

Tuesday 14th April

Yet another visitor and another first sighting of a three-year-old returnee this morning. This time it is a Glaslyn granddaughter, Blue 1H, landing on the nest perch. Blue 1H(12) is the daughter of Glaslyn born male,Yellow 37(05) now breeding at Kielder Nest 2. She never makes it onto the nest as 'Grandma' quickly sends her packing

Wednesday 15th April

At 12.47pm a male osprey, ringed Blue CU2, left leg (quickly nicknamed 'Jimmy' by Glaslyn staff), lands on the edge of the nest whilst the female is home. He stays for a few minutes until she chases him off. He returns later, four visits in total, his last being at 7.10pm. The Glaslyn female appears more tolerant of him and stops mantling. They even fly together at one point.

'Jimmy' also visited the Dyfi nest last August. He is a three-year-old, hatched in Dumfries & Galloway, 2012

Thursday 16th April

A male osprey is seen (Jimmy) very early morning on the nest with the female. Mating, or attempted mating takes place. He returns around 8.30am bringing a fish, which he takes to a tree behind the nest. Later, another male osprey shows up. It is Blue 80, hatched at Glaslyn in 2012, returning to his natal nest. He mates with his mother, having previously chased off Jimmy. She shows no animosity toward him as he commences to rearrange the nest.

Thursday 7th May

Shortly after 2.15pm, whilst the female is on the nest perch eating, the male pecks at, and partially eats the fourth egg. The female does not appear upset by this. He then starts cup-scraping and there follows a number of failed attempts to carry out the remaining shell in his beak only to have it roll back in again. He finally manages to carry it to a spot where it lodges at the side of the nest. He later shows interest in the fifth egg but does not remove it.
