A traditional pose this time of year, early Heron mating season.

This adult sits waiting for the mate to return with more sticks. Once a pair has mated and bonded both take turns gathering nest material. Since you can’t always tell by size which one is gathering it really can be a guess, or you have been watching them and see their interactions.
Hint; the male is dominant. Well, until he does something wrong one too many times. Then all hell breaks loose.
Ha. Does he get beaten with a stick or just pecked ?
Usually she will stand tall and give the look, and squawk, which is enough. Look at my home page here for an example of a discussion LOL
