Dear
Journey North,
Do you know someone that is always late? We have at least two
Whooping Cranes that are "late" this spring. Whereas
other Whooping Cranes are
already sitting on nests in Canada and in Wisconsin, these cranes
haven't even started the migration!
Who
Stayed Behind?
One whooping crane was sighted at Aransas National Wildlife Refuge
on April 30th. There could be one or two other cranes still
at Aransas. I haven't yet done an aerial search of the marshes
to
look for these stragglers. Also, a single whooping crane (#516)
from the new Eastern flock is still on its wintering area in
Florida.
Why No Hurry to Migrate?
These stragglers are cranes that are not yet old enough to nest.
Thus, they really have no need to get north since they don't
have to do any of the work involved with building a nest, sitting
on eggs, or feeding
young chicks. They can travel north whenever they feel like it.
I always worry that some of these late birds may be sick and
just don't feel good enough to make the migration flight. However,
they are probably just taking their time and will head north
when they want to. They are kind of like those people that get
to everything late and keep their own schedule. We'll keep checking
on these last remaining cranes to see if they do make the migration.
