It unfortunately appears that we have indeed lost at least one of the eagle eggs at the Norfolk Botanical Gardens. At about 4:34pm the Female was noted consuming an egg in the nest.
Behavior such as this likely indicates that something had occurred to the egg rendering it obviously unviable. There has been speculation that a particularly hard landing in the nest last night might have damaged the egg. This is a possibility, but again only speculation.
The egg eating behavior serves to recapture the valuable calories and calcium that went into creation of the egg. Egg formation is an energetically demanding process. We still have no confirmation of the second egg we were hoping had been laid. We will watch and hope for another egg. Although there is still time we are approaching the limit of typical laying period for bald eagles in Virginia.
