This has been been my nemesis bird for the last several years... I've tried unsuccessfully to get a decent shot of one, but to no avail. Today, while exploring a new wetland area, I came across a flock of them flitting among the branches, but, as usual, I'd no sooner get one in focus than it would fly off, frustrating my best efforts. Then this one landed on a branch about 10 feet in front of me, and just SAT there! I'm quite sure that was in direct violation of one or more articles of the "Kinglet Kode of Konduct", but I gladly took advantage of the opportunity... had to focus manually, because there were too many branches in the way for the AF to work, but this little fella just chilled while I tried different angles, looking for the best shot through the intervening sticks... None are perfect, but this is one of my favorites... 400mm, 1/250 @ f/8, ISO 1600.
