AIThe lost atlas
Extinct and prehistoric birds
Cave bones, specimens, and documents reveal an avifauna broader than the living list.
Reviewed:Three categories that must not be mixed.
Extinct means a species no longer lives; extirpated means locally lost but surviving elsewhere; prehistoric or subfossil means presence is known through older remains without confirmed modern observation.
Accidental describes a living visitor recorded outside its regular range. Placing it beside fossils confuses time, evidence, and conservation.

8linked profilesA focused selection connects the guide with verifiable species.
3reading lensesContext, identification, and practical decisions organized by topic.
3primary sourcesAgencies, research, and ornithological organizations support the content.
01
Historical specimens and fossil evidence
Puerto Rican Parakeet is studied through skins, skeletons, and archaeological material; its identity and range are reviewed by comparing morphology and context.
Caves and Pleistocene deposits document caracaras, rails, owls, woodcocks, doves, and passerines absent from the modern community.
02
How to read a lost-bird profile
Look for material type, locality, age, publication, and taxonomic certainty. An artistic reconstruction is not evidence for color or behavior the material does not preserve.
Collections of extinct, historical, and extirpated birds are different destinations. A profile should state uncertainty and never present ancient remains as modern sightings.

Birds to compare
Open each profile to review names, marks, audio, habitat, status, and sources.
01
Does prehistoric mean dinosaur?
No. Here it means birds known through remains predating sufficient modern or historical documentation.
02
Does accidental mean extinct in Puerto Rico?
No. An accidental is a rare living visitor; extirpated is local loss and extinct is total disappearance.
03
How do I verify an identification or claim?
Compare more than one mark, check date and place, open the linked profile, and consult the sources published at the end of the guide.

These sources support the editorial scope of this guide. Bird profiles also retain their own taxonomy, occurrence, and conservation references.
