Common Loon (Gavia immer), taken July 19, 2024, in New Hampshire, US
Loons are absolutely fascinating to watch. This specific individual was going about the lake with its mate and another pair of loons, possibly from a neighboring lake. It got close enough for me to run out on the dock and try to get pictures at like 8 in the morning, but sadly the sun was on the wrong side of the lake lol! At least the backlighting looks cool!
