Returning Dyfi female chick from 2013, Blue 2R, Clarach, lands on the nest c11.40am. Aran escorts her away

Friday 13th May

Clarach pays another visit. She arrives at 6.33pm and stays until 10.23pm. Mrs G appears quite comfortable with her and shows no hostility. When Aran brings in a fish Clarach snatches it from him. She eats ravenously on the edge of the nest

Saturday 14th May

Clarach shows up at 4.22am. Aran brings in a fish at 5.47am and Clarach gets in first again. She sits on the edge of the nest with the fish under her talon for a time. Mrs G eventually reacts and all three birds take to the air. All settles down after this and Clarach does not return to the nest. Mrs G gives intruder alarms from time to time which suggests she is still around. Aran later brings Mrs G a whole fish. She eats on the perch whilst he incubates

At 11.20pm Blue W8 falls from the nest perch into branches directly below. He remains there until a fish is delivered by Aran at 4.21am when he takes flight and gets himself back to the nest. He makes a clumsy landing but is apparently none the worse for his tumble
