It does not get any better than this. We were watching this Black-throated Blue Warbler feeding in the foliage a few yards from the boardwalk at Magee Marsh on the Eire shore of Ohio, during the Biggest Week in American Birding, when it popped up onto the trunk of a big tree just a few feet from the rail of the boardwalk. I had to zoom back from 600mm equivalent to fit the whole bird in the frame. 🙂 It was fast and hopping all around the trunk, looking for bugs in the crevices of the bark, so it was not easy to catch. Lucky for me (and the other dozen or so other delighted photographers and birders) it worked the trunk for a good five minutes, during which time I shot off a hundred or more frames. Bound to have a few keepers. 🙂 Sony RX10iv at 490mm equivalent. Program mode with my custom birds and wildlife modifications. Processed in Polarr.
