## TL;DR

Birds are feathered vertebrates in class Aves. The repaired article avoids unsupported species counts and extreme examples unless directly sourced, focusing on defining traits, feathers, and migration.

## Core Explanation

The stable overview is that birds are distinguished by feathers and other anatomical traits, that feathers support flight, insulation, and signaling functions, and that migration is a recurrent movement pattern used by many species in response to seasonal or ecological pressures.
