I don't get it - how they weave twigs together to make a cohesive nest with no holes in the bottom for eggs to fall through. How is this "instinct" programmed?
The colony of Great Blue Herons in the top of this pine tree
Incoming twig
A large incoming twig
Passing the twig to the female
The next door neighbor watching
Another incoming twig
From time to time there is a breat in nest building - more "kissing" - bill touching and holding
Perhaps mounting the female for copulation
