A Quick Summary
Glesni
Our breeding female of the last five years has still not returned. Obviously it is looking increasingly unlikely that she will come back as each day passes, but we're not drawing a line under the Glesni chapter just yet, let's wait a few more days.
A breeding Kielder female has only just arrived back at her nest, well over two weeks later than last year - thanks Joanna :-). 2018 is turning out to be a very unusual year for returning migrants, we'll just have to sit it out and see what develops.
Q. What will happen to Blue 3J if Glesni returns?
A. Exactly what you think would happen most probably, but it depends on her strength and condition. Glesni would try and displace her cousin Blue 3J off the nest and, if any eggs had been laid, kick them out. There are a lot of variables including the biggest of all, will she come back? Let's wait and see how things pan out.
