Choosing among birding field guides & calls comes down to the kind of reference collection you want. One lot points clearly toward exotic and North American species in illustrated hardcover books from the 1970s. The other leans into varied bird-watching subjects and carries a Very Good condition label. Both are mixed collections, so the choice is about scope, format, condition, and price rather than a single definitive guide.
Quick verdict
The Peterson lot fits a shopper who wants a focused species-reference collection at the lower listed price. The Ornithology lot fits someone prioritizing a Very Good condition label and a broader bird-watching mix. The deciding trade-off is specificity versus variety, not their shared United States origin or Animals & Pets genre.

The Very Good condition label is another concrete reason to favor it when condition wording carries weight.
Product notes
Lot Of 7 Bird Species Ornithology Peterson Exotic North American Guide

Choose the Peterson lot when the search centers on exotic and North American species, or when an illustrated hardcover reference with a dust jacket fits your shelf. Its 1970s publication era gives the collection a clearly vintage character, and the description identifies English books for adults, young adults, and ages 9-12. At USD 23.99, it is the less expensive price in this matchup. The limitation is its mixed-lot structure: authors and book titles vary, so the reading experience may be less uniform from volume to volume. The condition is marked Good, which makes the other lot's Very Good label worth considering if condition wording is central to the decision.
Ornithology Birds Books Lot (7) Bird Watching Species Guides & Books (USED

Pick the Ornithology Birds Books Lot if you want bird-watching species guides with varied topics across a mixed collection. The description emphasizes multiple perspectives on birds, while the attributes identify English nonfiction books, mixed authors and publishers, and a Very Good condition label. That combination makes the lot a natural fit for browsing across bird-related subjects. Its limitation is the same variety: a mixed-author, mixed-publisher set may feel less consistent from book to book. At USD 30.59, it carries a $6.60 price difference versus the Peterson lot, so the choice rests on whether its bird-watching emphasis and condition label match your priorities.
