Did you know that Great Blue Herons land in trees? Yeah, me neither. And not, like, big dead trees with big branches: these guys were all landing in the very top of some wobbly spruces! I counted fifteen of them together, and there were probably more in the branches, continuously coming and going. Very enlightening.
