I know, Roger Torry Peterson died in 1996, but I’d rather refer to him in the present tense in this case. He was an ornithologist, and made some wonderful field guides. Included in them are little arrows that point to unique identifying marks on birds that will help pinpoint the species when there might be confusion.

I mostly use Sibley’s Guide, but I like having Peterson’s guide around for a second opinion.
