An individual bird that has wandered far outside its normal range, often due to storms or navigational errors.

The smaller feathers that cover the bases of the main wing and tail feathers, helping to streamline the bird’s shape.

The behavior of hiding food (seeds/nuts) in various locations to be eaten later when food is scarce (common in Blue Jays).

The study of a bird's beak shape, which is directly evolved to suit its specific diet (e.g., hooked for meat, thin for nectar).

Describes chicks that are hatched blind, featherless, and completely dependent on their parents for survival.

The practice of everyday birders reporting their sightings to apps (like eBird) to help scientists track global bird populations.
