Not sure if I've told this story, but bear with me if I have; last year, I was weeding the gardens around the outside of my pondhouse. Middle of the day sort of thing, so quiet, no one else around. I didn't even hear it but saw peripherally to my right, something move. I looked and a blue heron stood on the fence separating my yard from my back neighbor's. It was so quiet, just standing there. I cursed under my breath, but only because I didn't have my camera handy and knew if I moved, it'd take off. So, I just watched. Didn't move, just waited. It started to get into my brain that it was still late May and I hadn't unrolled the top screen over my pondhouse yet. Would it fly up top? I didn't think so as I have 4'x4' latticed opening that should/would impede it's entry or takeoff, should that be a possibility. Still, I wanted to know. So I was waiting and watching.
The heron flew then from the fence-line, perhaps 15' away, and down to the southeast side of the pondhouse (I was working on the west side). Since everything is screen, I sorta could see it as it slowly made it's way from the SE corner to the NE corner. Turning it would mean it would come between the house and pondhouse, something I also wondered about (would it be leery of close proximity?). It turned back to the south and then repeated the pattern, I guess looking to find a way inside the screen. I think this went on for like 20 minutes until it finally decided to turn the NE corner and move toward the doorway. Now, I know they're smart but I didn't think it would actually try and pry between the screen door and the jamb but...
It finally passed the door, again continuing with it's circle pattern of the pondhouse. You know it could hear the water and knew where the fish were...I never moved even as it turned the NW corner and started toward me, unaware I was even there. Well, I'd had enough and was bored; the bird wasn't going to attempt going through the ceiling lattice and that's all I really needed to know. I suddenly stood up and before I could say anything/wave my arms, it lifted in a silence of wings that was amazing. Not a sound, and it moved so gracefully, almost rising vertically toward the roof of my house. As I moved to follow, it flew and landed on my neighbor's rood to the west, looking back at me as if to say; some day, yep; some day!
There, that's MY heron story and it didn't include netting the pond nor cursing/crying at any fish loss.
And I bet none of you will ever believe I screened the whole pond in without ever thinking 'what if a heron stops by?'. Nope, I was out to stop the more nefarious predator; mosquitoes!
