It won’t be long now and the “wild ones” will be thinking about returning to WBNP and nesting. Some of their cousins, the sandhill crane have already started their mirgration. At this time, the wild ones are still enjoying the blue crabs that, thankfully, have been plentiful this winter at ANWR.
Why are blue crabs so important to a Whooping Crane’s diet? The Whooping Cranes require blue crabs to build up their body resources and reserves for their long journey home and for successful nesting. Without a sufficient supply of blue crabs to eat during the winter, their chances of a successful nesting season and raising chicks is drastically reduced. Blue crabs are rich in protein but more importantly, the meat and shells are highly rich in calcium, necessary for strong bones and also for forming eggshells.
In the photo below, you can see a Whooping Crane foraging for blue crabs as one looks on.
With those long pointed bills, the blue crab below was no match for the whooper.
