I saw my first Green Heron this year while at Delta Ponds this morning. It was very skittish and I had a difficult time getting a shot of it. I suppose that's because it just arrived at the Ponds where quite a few people walk each day. If it stays long enough perhaps it will get used to us.
In previous years it has been a little easier to get close enough for photos. But the Green Herons in those years arrived earlier and stayed longer than we will probably see this year. The waters in the Ponds have been high all spring, and they are still a little high even now. So I am not seeing as much wildlife yet, like I have in previous years. Perhaps this will help you to understand why I was thrilled at seeing the Green Heron back again.
