January 24, 2018 . Pairing behavior of Great Blue Herons

I’m beginning to see patterns of behavior during pairing of Great Blue Herons.  Here are some examples.

The Stretch

Usual flying configure when working -  with the neck in the "S" configuration

During pairing, though, the male flies circles around the nest and his prospective girlfriend - with his neck extended.

Sometimes there is a lookout

Scratching his face

Passing a twig from male to female

Off to fetch another twig  (nest building materials)

Returning with a twig

Passing the twig

Off for another twig

Fetching another twig - Neck in the "S" configuration

Returning with a twig

Off for more twigs

Passing the twig to the female (the construction supervisor)

Returning with another twig

Time out for circular flying to impress the female (straight neck)

January 22, 2018: Great Blue Heron Harvesting

After watching early nest building, pairing  and mating of Great Blue Herons, the next activity seems to be the male searching for suitable twigs and moss while the female weaves them into the nest.

I love the lighting of this image

Once the twig is harvested, the male returns holding the twig in his mandibles
