The next time I was able to return to the osprey (Pandion haliaetus) nest that had been taken over by a pair of Canada geese (Branta canadensis) the nest was empty (see Surprise Tenant 2). Had the geese been evicted and the eggs or goslings destroyed by the osprey, or had the family survived?
I began to examine the ground under the nest looking for egg remains or other evidence of why the nest was empty. All I could find was one dead gosling. The young bird was very fresh and appeared to have only recently died.
Since this did not look to be a newly hatched chick, my assumption is that the goslings remained in the nest for a couple days before taking a plunge to the ground at the urging of their parents. That was a long fall!! Enough of the egg sac remains, enabling young goslings to not eat for the first two days of life, although they are capable of pecking for food, walking and swimming almost immediately after birth. What happened to the parents and other goslings, if there were any. So. . . . .
