For the last few months, I've regularly visited the
Tracy Brook Wildlife Sanctuary.
As a result, I've been able to track particular nests.
Here's a sequence, mostly of one nest, of two chicks from conception to
about ready to fledge.
Great blue heron
Here is a shot of two great blue
herons
mating, on
April 12. Note the shape of the trunk of the tree.

Note the cute, fuzzy chick! This is the same nest
as in the first picture, about seven weeks
later.

27–29 days.

The chicks have gotten big. They may be about
to fledge, or may have already done so.
