Now there is a report from Hailuoto, written by the ringer Matts Finnlund.http://www.luotio.fi/forum/viewtopic.php?f=92&p=54108&sid=3572cf26e18da167f0fab102a8b7b6a2#p54108
I´ll try to translate something here in English:
1) M-60700 left foot, wing 31,4 cm, weigth 1,540 kg more developed (Leo)
2) M-60699 right foot, wing 29 cm, weight 1,480 kg (Matts)
The chicks were well-fed and calm, the ringing went fine. The chicks were ringed in the nest. Mother osprey stayed near and watched the situation and dad osprey was away, probably catching fish. The feet of the ospreys were quite similar compared to each others and they are assumed to be males.
They (people) tried to look the dead chick from outside from large area (mother osprey had removed it already from the nest). It could be wisest to remove the dead chick as far away as possible. Because it can draw seagulls, crows and other birds that hunt into the same area. However the people did not find any signs of the dead chick. It is assumed the mother osprey has carried the dead chick away in her feet. Because if it´s carried in the beak it´s not possible to be carried far away, since it can weight almost 1 kg.
Because the nesting started 3 weeks later than normally, the fish catch can be smaller than usually. Now it will be interesting to see if the mother osprey stays here 3 weeks longer or will she migrate normally. Normally the migration starts in August. If she leaves early (or at normal time) the chicks will be left without mother´s care which should last in normal circumstances 3 weeks longer. But it is possible that the mother osprey stays here longer. At least once they have seen a mother osprey which stayed here until late September and took care of her chicks. Normally mother migrates first, then dad and the chicks will be last to migrate.
