Whooper Question #9
Date: Mon Apr 17 2006 - 17:58:35 EDT
Dear Journey North,
It takes approximately 30 days for whoopers to incubate, so these pairs' eggs should hatch on the following dates:
#101 and #202: May 7th
#213 and #218: May 6th
#203 and #317: May 7th
#211 and #217: May 11th
Whooping cranes lay two eggs, but only one young usually survives, because the one that hatches first gets a head start and is aggressive toward the second one. They lay two eggs to be on the safe side. If they can raise both chicks, they do, but if one chick is weak or doesn't make it for some reason, they have the second one as a "backup."
