hmmmmm. One of the nest monitors pointed out to me that the ospreys at the Arb were off their new egg a lot overnight last night…..see photos. I reviewed the tape and it is a bit concerning. Ospreys may be off the eggs for short periods without much harm….and there is a behavioral strategy called ”delayed incubation” in which they chose not to incubate eggs fully until subsequent eggs are laid. The result of this is that the eggs will hatch closer together, rather than hatching several days apart as they are laid several days apart. Of course we cant know what the ospreys are thinking or what is causing their behavior. Eggs can die from getting too cold also….but we will keep watching for more clues. Note the time stamps on the images….
