Could contaminents cause more than issues with egg laying and hatching? Could a threshold of effect be reached wherein the eggs are laid and hatched successfully but hatchling issues such as we have seen with the first PH chick and possibly the second come into play and the breeding fails?

Perhaps if these chicks have some sort of susceptibility due to contaminents and if they had been taken from the nest for hatching as per last year, the more sterile environment and planned special food feedings might have resulted in their survival?

It is possible that DDE, or other contaminants, could have physiological effects on the chicks. The northern Channel Islands project is a feasibility study to see if bald eagles can make it on their own, so we don't have any plans to manipulate the nests like we have done on Catalina (removing eggs, fostering chicks, etc.). It is possible that if the PH chicks were hatched in captivity that they could have survived, depending on what the problem was.
