Egg Rotation

Both ospreys have frequented the nest more the last three days than they did over the weekend, but their ongoing absence is disconcerting. Last Friday afternoon, 28 March, the female was seen rotating the eggs then covering them with Spanish moss. That was the last time I saw them. The first egg was laid 18 days ago, the second, 15 days ago, and the third, around 12 to 13 days ago. If the eggs are successful, it generally takes 5 – 6 weeks until the eggs hatch.

Yesterday I witnessed both ospreys looking up and following an object in the air circulating about them. Both birds were lifting their wings and squawking about the nest. This could be an intruder osprey or predator bird which may be keeping them off the nest.

Both ospreys have continued mating, which is a good sign, and repairing the nest with sticks, moss, and various vegetation from the several storms we’ve had since Saturday, which also could be keeping the osprey off the nest more so than usual, though I would think they would uncover their eggs to rotate them and check on their general condition. The female was seen this morning with her head down over the area where the eggs were last seen then flew off shortly after. Both birds seem to be taking turns again on the nest as they did in the previous weeks.

Time will tell where the eggs are concerned. Keep your fingers crossed for a successful clutch and stay tuned in.
