This is what it looked like on Thursday afternoon. What took away all of those large feathers and many of the downy feathers. The entrails were disposed of my flies and ants. Would they do feathers, too? The missus thinks other birds took them to 'feather their nest', but most birds are done with that for the summer.

Any ideas?

I don't know the particulars, but it looks like you have great clean up crews in your yard.

Definitively dove feaathers and it was most likely the Redtailed Hawk. My backyard is Dove Central and once or twice a week I see the same picture. All it needs is a good windgust and the feathers are in the bushes or in my neighbors yard. Usually the small, fuzzy feathers get hung up in the grass and stay.

I saw this once in my backyard.

I'd walked through that part of the lawn an hour earlier, was gardening no more than 30-40' away, and missed the whole incident. Then, headed back to the house, without warning I found myself looking down on an explosion of gray feathers.

Nothing else was left, but sudden violence could be the only explanation.

I'm not sure there are any doves left at this point....

Birds are not the only critters who like to line their nests with something soft and warm .... squirrels and mice are quite quick to snatch up such a bounty of free insulating materials ...
