Abstract
Field Guide to the Birds of North America is a complete, compact and user-friendly guide to all the birds of the USA and Canada (excluding Hawaii). Drawing on years of guiding experience, the book is perfectly designed for use in the field. Pocket-sized and at just 372 pages, it covers 1,100 species – more than any other guide to North America – and includes over 6,000 illustrations. Distribution ranges of all native birds are mapped, and many confusing subspecies are included for the first time in a field guide for the region. The book gives special attention to the key differences between troublesome species, with comparisons to help the reader get to the right identification. Compact and comprehensive, this new field guide includes: - Color-coded maps showing resident and seasonal distributions to help plan which birds to expect when and where. - ‘What’s the difference?’ information boxes providing easy guidance on the most challenging species to identify. - Conservation and abundance status, with subspecies separately mapped. - Current taxonomic order and up-to-date common names. The clearly labelled illustrations detail plumage variations by sex, age and color morphs. Birds are illustrated in flight, in profile and in typical habitats. Concise descriptive captions highlight the most important field identification signs, including habitat, nesting and feeding behavior. Calls are described for every species. Written and illustrated by a professional birding guide with decades of experience, Field Guide to the Birds of North America is a must-have book for birders of all ages and any level of experience.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
