The 97 pages that link to Bird, each with the reason it gives.

• MammalCompared with: Birds share endothermy with mammals but have feathers rather than mammalian hair.

• SquamataCompared with: Their distant reptilian relationship contrasts with the close living kinship among lepidosaurs.

• MammaliaCompared with: Birds, like mammals, are endothermic, but they evolved this trait independently.

• PterosaurCompared with: Birds evolved flight independently and used feathered wings rather than finger-supported membranes.

• Evolution of birdsBroader topic: The living endpoint of the history includes a highly diverse group of avian species.

• K–Pg boundaryRelated: Some bird lineages survived the extinction, unlike other dinosaurs.

• ArchosaurBroader topic: Birds are the only living descendants of non-avian dinosaur archosaurs.

• Dosage compensationCompared with: Birds have ZW sex chromosomes and generally show incomplete compensation across the Z chromosome.

• MoultingBroader topic: Birds replace feathers in patterned molts while maintaining flight and insulation.

• PteranodonCompared with: Birds and Pteranodon both flew, but their wings evolved independently from different anatomical structures.

• PterosauriaCompared with: Birds are living flying archosaurs, but their wings evolved independently of pterosaur wings.

• SauropsidaBroader topic: They are living dinosaurs and therefore members of Sauropsida.

• CorvidaeNarrower topic: Corvidae is one family within the class Aves.

• OwlNarrower topic: Owls are a specialized group within the broader diversity of birds.

• PasseriformesNarrower topic: Passerines are one order within this broader class of vertebrates.

• SaurischiaBroader topic: Their theropod ancestry shows that one living dinosaur branch belongs within Saurischia.

• ArchosauriformesBroader topic: Living birds preserve one surviving dinosaur lineage of archosauriforms.

• Chicxulub impactorRelated: A small number of avian lineages survived the extinction that eliminated other dinosaurs.

• DeinonychusNarrower topic: Deinonychus’s anatomy helped strengthen arguments linking birds with theropod dinosaurs.

• GastrolithBroader topic: Many birds swallow stones that collect in the gizzard and help process food.

• PigeonNarrower topic: Pigeons share the defining anatomy and biology of birds.

• ReptiliaCompared with: Birds are often contrasted with reptiles in everyday language but are reptiles phylogenetically.

• FinchNarrower topic: Finches share the defining anatomy and biology of birds.
