There may be up to 75 Great Blue Herons communing in one heronry, but on our lake there are only two, as far as I can tell. They may be a couple, and if so, they probably have nestlings nearby, and if there are nestlings nearby, they'll be ready to fly the coop sometime in July-- according to my internet sources. I'll let you know if I spot any real-life baby bird activity.
To tell the truth, I haven't even heard the herons call out there. I had to listen to the call on Wikipedia, and I'm glad they're not chatty because the heron honk sounds like an angry trucker laying on the horn.
We have seen them, though. We all climbed in the boat yesterday and very quietly followed, and attempted to photograph, both herons. We were mostly unsuccessful, but it is peaceful out there. I'm not much for zooming around the pond at high speeds-- too many goose bumps, too much hair whipping-- but I do like it when we turn off the engine just drift for a while. That's just what we were doing when the heron took off, and I took the photo above. Yep, it's a bit blurry. I'm still learning.
In the meantime, here's a nugget I Wikied about herons:
"Herons are also known as "shitepokes", or euphemistically as "shikepokes." Webster's Dictionary suggests that herons were given this name because of their habit of defecating when flushed. The terms "shitepoke" or "shikepoke" can be used as insults in a number of situations."
Just remember, if you choose to use shikepoke as an epithet, you'll be calling someone a beautiful, faithful bird-- although they do eat frogs, snakes, insects and sometimes other baby birds, so there's that.
