What's Going On?

In the past few days our ospreys have taken an apathetic attitude toward their three eggs. Neither osprey has been seen sitting on the eggs considering the cold front that came through Saturday afternoon which is a concern. Also, the nest has been left unattended more than ever before. Usually an osprey will fly off after its mate is there to watch over the eggs.

I’m hoping we will not have a replay of last year. This is quite strange for both birds to be so attentive then to be so disinterested. Over the weekend the female osprey was mostly on the back edge of the nest and occasionally would lean towards the eggs location, but nothing more.

Three Eggs

We now have our third egg on the nest. Osprey generally lay two to four eggs so it is possible for another egg in a day or two. The female has been seen rotating the three eggs and spreading her wings out and squawking. A predator bird or another osprey may be in the vicinity.

And Then There Were Two

Our resident couple now has two eggs on the nest. The female continues to move Spanish moss, sticks, and other material about the eggs to safeguard them.

Correction

An avid osprey viewer contacted us indicating that the egg was laid Saturday evening betweem 6:00 pm and 7:15 pm and not Sunday morning as first thought.

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.

Osprey Eviction

A lot has been going on since the last log update. The pair of osprey that had been on the nest for most of February has been evicted. Another pair of osprey has taken over the nest. Thought to be Olivia and Ollie at first, their markings indicate otherwise. These osprey have brought more Spanish moss and sticks to the nest forming it into a bowl shape. The female has been seen with her head pointed downwards as if deep in thought and the male continues to brace the structure.
Last year the first egg was laid on the 22nd of March so we are hoping that eggs will be laid in the near future.
