Another case of polygyny

I woke up in the middle of the night and remembered yet another instance of polygyny in our population of Ospreys. Another male who was attending two nests that were almost in sight of each other. These two nests were not as close as our most current case. Chicks hatched on both nests, three chicks on one nest and a single chick on the other. Sadly the single chick was found dead below the nest, probable predation. So, once again, only one nest was successful. That brings the total cases of polygyny to seven,that I know of. And only once did both nests succeed.
