Friday 27th March

Female 5N(04) arrives back at Rutland. First osprey of the year to land on the Manton Bay nest, which she does at 12.51pm

[Before her arrival, a pair of Egyptian geese had taken up residence on the nest. They continue to visit frequently when there are no ospreys around, excavating quite a hole in readiness for eggs]

Saturday 28th March

Female 25(10) puts in a brief appearance on nest around 2.40pm. She had returned to Rutland the previous week

Sunday 29th March

Male 28(10) arrives back at Rutland. Sits on the leaning perch in Manton Bay for a while before landing on nest at around 5.20pm

Monday 30th March

Busy day in the bay. Three ospreys around. 28(10) arrives first at 10.00am. Carries a fish to the T-perch where he stays for a couple of hours.

At 1.00pm 5N(04) flies in, lands on nest and sits for around 15 mins whilst 28(10) is still on the T-perch eating his fish. 28(10) then leaves the perch and circles the nest. 5N(04) watches him for a few minutes then flies off the nest. Both circle together then settle side by side on the T-perch.

25(10) appears and the three of them do a fly around between nest and perch. Landing, then taking off again.

At around 2.30pm 28(10) flies over and attempts to mate with 25(10) who was at that time sitting on the nest. Unsuccessful attempt, but 25(10) appears receptive.

Around 3.15pm both females depart leaving 28(10) alone in the bay.
