The picture of this White-throated Sparrow in breeding plumage was taken at the New York Botanical Gardens.

The picture of this White-throated Sparrow in breeding plumage was taken with the CANON EOS7D and the CANON 100-400mm lens and the CANON 580EXII flash.

To me, it looks like this White-throated Sparrow put on a shiny tuxedo for the breeding season.
