Fluffed Goldfinch

American Goldfinch
We may still have 3 feet of snow in the yard, but the Goldfinches are coming into summer color, so spring must be creeping up on Southern Maine. This Goldfinch was at the feeder, and then popped up to a branch overhead. It is “fluffed” or “puffed”…with its breast feathers standing out from the body. Birds fluff for several reasons. On particularly cold mornings you will see them perched and fluffed before the sun comes up or just after. The additional air trapped in the fluffed feathers acts as insulation to keep them warm through the night. They might also fluff in the first sun of the day…sitting directly in sun…in which case the spread features allow the sun to get in closer to their bodes and warm them faster. Occasionally on a particularly hot day they might fluff for exactly the opposite reasons. Finally, they fluff to allow the sun in were it can kill feather mites when they reach troublesome levels, as they might after a long cold Maine winter. It was not particularly cold when this images was taken, so I suspect the mite cause for this bird.
The image was cropped slightly for composition, but it shows the incredible detail possible at 2000mm equivalent field of view with the new Nikon P900 superzoom bridge camera…at least in good light. You should view it a full screen. 1/500th @ ISO 220 @ f6.5. Processed in Topaz Denoise (it did not really need it, but Topaz is a new toy today) and Lightroom on my Surface Pro 3 tablet.
