First Egg Laid

A storm blew through this weekend bringing heavy rain, thunder, lighting and an egg. The egg, which was laid Saturday evening, has the usual mottled characteristics. Both ospreys have been sharing parental duties caring for the newly laid egg.

Over the course of the weekend, the nest has taken on more branches and moss creating a deeper bowl shape ensuring the safety of the egg. Osprey usually lay 2 – 4 eggs one to two days apart so additional eggs should not be too far away. Osprey eggs do not hatch all at once, but instead the first chick hatches out up to five days before the last one. The older chick dominates its younger siblings, and can monopolize the food brought by the parents. If food is abundant, little aggression is seen amongst the chicks, but if food is limited, the younger chicks often starve.¹

Check back to see how many eggs our osprey couple will ultimately bring about and also for pictures in the gallery.
