A female has arrived, and might be interested in a partner already.
The ‘stick ritual’ has begun.
The female liked the nest and right away the male started offering sticks. It’s a lot like buying her flowers.
While she didn’t take this stick, she didn’t fly off either.
There will be sticks, fights, even hugs, building a bond. They need that, when things get serious young Herons are a lot of work.
