Kind of late to jump in, but I also think it is a female summer tanager. I've seen lots in winter / spring in Mexico and Venezuela and this one looks very similar. As far as the male's plumages go, I've seen many winter residents and they are always red, and I've seen a good number of them in the States in spring / summer and they are still red. I can't say that the shade of red is identical but it is always red. Saw several males and females just yesterday outside of Houston, Tx as they passed through on migration.
