A few more...

Today I visited about 20 nests and found only two of them occupied. Tho one of the females was not on the nest she occupied last year! This time of year it is always like musical nests and I love to document all the movement. Many sources say they mate for life, but I have seen a lot of "divorces" , mate swapping, nest swapping, in my 22 years of studying these magnificent birds. Some Ospreys do seem to have long term relationships with a partner, but many have a series of different partners, sometimes due to death, but also due to a pair splitting up. They seem to split after a failed breeding season, so it makes sense that a new nest and a new partner might provide a better chance at reproductive success.
