For birding field guides & calls, the key decision is scope: do you want one straightforward bird identification field guide, or a deeper reference collection for studying species, nests, eggs, and difficult identification problems? The Easton Press Roger Tory Peterson Field Guides 50th Anniv, Birds & Ornithology takes the second approach. At USD 83.88, it is aimed at readers who want a substantial, book-centered bird watching reference rather than a single quick-reference volume.
Quick verdict
The Easton Press set is a strong fit for someone interested in North American bird identification alongside nesting and egg references. Its leather binding, illustrated format, and Collector's Edition designation give the collection a distinct presentation, while the subject coverage reaches beyond basic species recognition.
The main trade-off is commitment. This is a lot of seven books, so the format makes more sense for a reader who wants a broad reference collection than for someone seeking one focused field guide.
Easton Press Roger Tory Peterson Field Guides 50th Anniversary Edition

The clearest reason to choose this collection is its range. The named volumes include *Eastern Birds' Nests*, which covers nests and eggs of 285 bird species found east of the Mississippi River, *Western Birds' Nests*, which addresses 520 species breeding west of the Mississippi River, and *Advanced Birding*, a guide to challenging North American identification problems. Together, those subjects give the set a specific role: supporting closer study of birds and their nesting details, not just quick name recognition.
One limitation follows directly from that same scope. The collection may be more than you need if your goal is a single bird species guide for occasional identification. The nest-focused books and advanced identification material create a more specialized reading experience than a general-purpose reference alone.
Who it suits
Choose the set if your interests include Eastern or Western bird nests, egg characteristics, breeding habitats, nesting materials, or subtle differences between similar North American species. It also suits readers who appreciate a physical reference collection with leather binding and illustrated content in English.
The collection is less straightforward for a shopper whose priority is a narrow topic. A reader focused only on general species identification may not make full use of the nest and advanced-birding coverage. That is not a flaw in the set's design; it is the central question of whether its breadth matches your interests.
What stands out
- Distinct subject mix: Eastern and Western nest guides sit alongside a volume devoted to difficult identification questions.
- Detailed nesting coverage: The descriptions include habitats, breeding seasons, nest construction, nesting materials, dimensions, and egg coloration.
- Book-focused presentation: Leather binding and the illustrated Collector's Edition format make the collection suited to readers who want a lasting reference set.
Meaningful trade-offs
The seven-volume format is the biggest practical consideration. It offers more subject coverage than a single book, but it also asks you to engage with a collection rather than one streamlined guide. The set's specialized focus on nests, eggs, and difficult identification means its appeal depends heavily on those particular birding interests.
Bottom line
For readers seeking a leather-bound, illustrated bird watching reference with dedicated coverage of nests, eggs, and challenging North American identification, the Easton Press Roger Tory Peterson collection is a focused choice. If you want one general bird identification book, its multi-volume format is the deciding drawback; if deeper study is the goal, its subject range is the reason to choose it.
