Jordan Lake. HATCHED! Yes at least one egg has hatched. The way I know that – because obviously I cannot see down into the nest – is by the parent’s behavior. When the parents begin bringing in fish, then stand on the edge and pluck off bites of the fish and reach down to feed it to the chicks, we call that “feeding behavior”. That’s how we know that there’s a chick in the nest – mouth wide open wanting that bite of fish. Yay!
