My gander is getting feisty now, too. This is his fourth breeding season, and I've noticed it gets easier to be around him every year. I don't think his temperament is any less than what it was the first year, but I am getting better and better at handling it - both consciously and unconsciously. I'm much more fluent in The Language of Gander.
I now know his protectiveness increases, the closer he is to the nest. I know to let him stay between me and the goose, especially if I'm carrying something (like a bucket or a broom). I know to look for the little signs that he's starting to get riled up, and I stop and greet him and talk to him until he's calmer, and then I sloooowly continue what I'm doing. If he won't calm down, I reach out and ask him "Do you want me to pick you up?" - he very much does NOT want that, so he'll usually back away. And when he turns full gander on me, I know I can pick him up, carry him to the pond and dump him in it. It seems that physically removing him from the situation plus placing him in another element makes him forget what he was mad about. Also, for some reason he never tries to bite my face.
I'm not yet a certified gander whisperer, and I'm likely to get decorated with bruises like last year - he's already dealt me one good bruise on my forearm. But this year I'm hopefull I'll also have patches of regular arm among the bruises.
