It is also missing some flight feathers. I was not sure if that was molt or predator. I suspect the latter.

>> Breeding of Golden-crowned Sparrow anywhere in the lower 48 is almost unheard of. The breeding range is much further north, in the Yukon and central Alaska. The breeding habitat there (typically scrub-tundra and some mixed conifers) is also unlike our local habitats. Adults don't typically arrive on breeding grounds until May and egg dates are mid-May to mid-June, so this would be very early. Unlike many species, there has been no documented change in range of this species, although there is still much to learn about Golden-crowned Sparrows. To date, I only know of one study dedicated to breeding biology of this sparrow and it was published in 1987. There are some scattered summer records of Golden-crowned Sparrows in the US (outside of Alaska), even one from Florida, but these are all wandering individuals out of range, not breeding birds.
