I saw my first Green Heron for this year today at Delta Ponds. They summer here in Western Oregon. They are usually seen along shaded edges of ponds, which is where I saw this one. They get their name from the green color of their back, also noteworthy are their yellow legs. Fortunately, the heron landed on the edge of the pond where I was standing. They can be elusive, especially when they first arrive at the Ponds.

"From a distance, the Green Heron is a dark, stocky bird hunched on slender yellow legs at the water’s edge, often hidden behind a tangle of leaves. Seen up close, it is a striking bird with a velvet-green back, rich chestnut body, and a dark cap often raised into a short crest. These small herons crouch patiently to surprise fish with a snatch of their daggerlike bill. They sometimes lure in fish using small items such as twigs or insects as bait." - https://www.allaboutbirds.org/guide/Green_Heron/id" >From All About Birds
