I have seen thousands of chickadees over the years, had hundreds feed out of my hand, and this is the first leucistic chickadee I have ever seen. This is the first leucistic bird of any species I have seen. Many thanks to Hank for alerting me of its whereabouts.
 
This was the most difficult shot I have taken in recent times. This chickadee was constantly on the move and it was not feed-out-of-your-hand tame like the chickadees at our popular conservation areas are. I was following the chickadee with my camera as it emerged from the bushes and as soon as it perched on this branch I fired off a series of shots. My camera could only get three shots at 8 frames per second before the chickadee flew out of the frame, which means the chickadee was only in this position for about 0.38 seconds! That was about the longest it ever stayed still out in the open like this. I managed a couple of other series of shots, but they were taken when the chickadee was in the bushes with a million branches going every which way through the frame and across the chickadee itself. This was the only clean shot I managed. I had to leave at 1 pm and if you look at the exif info you'll see what I mean when I say that this shot came at the last moment!
