Green Heron

Erika spied this Green Heron at a pond in Northfield on 26 July 2018. As is usual in my dragonfly-hunting old age, she was quite a distance ahead of me. Probably because the bird is young, it did not fly while Erika wildly waved me forward. The bottom-up attitude of the second photo is a bit uncommon in Green Heron photos. We were just at the right place at the right time. I believe the heron struck out at whatever it was trying to spear. Green herons are usually fish-eaters, but will take whatever invertebrates and amphibians they happen to find. Capture rates of 57% are reported in the literature (Davis and Kushland 1994).
