Today at Kielder the strong winds have turned into more of a breeze and the sun is shining most of the time. The males have brought fish in to both Nests 1 and 2 and the chicks have had several meals. The females have left them uncovered in the sunshine for a minute or so, a novelty for the youngsters!
As you can see there are no more hatches. One of the Nest 2 eggs is definitely not viable after being on the edge of the nest for a week. The other should hatch soon if it was undamaged in the intruder incident on 9 May. Sadly the egg on Nest 1 won’t now hatch. It seems very light so probably was not fertilised. Comparing images of the eggs we think it was the first to be laid. Mrs YA laid that egg just 8 days after she returned to the nest which is a very short interval between successful mating and an egg. Previously she has taken 17 days or more to produce the first egg – a bit on the long side. So possibly that early laying was a factor, but we don’t know the reason. You can judge how light it is in this video. A newly hatched chick weighs about 40g.
