When entire populations of a species migrate.

Partial Migration

When only some individuals of a population migrate while others remain.

Differential Migration

Variation in migration patterns within populations based on age or sex.

Seasonal Migration

Predictable migration that occurs during a particular season.

Irruptive Movements

Hierarchical Classification

A system that organizes species from broad to specific categories.

Hierarchy list

The full sequence is: Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species.

Spatial Migration

The distance and altitude of the migration 

Altitudinal migration

 migration between different elevations (some birds migrate to higher elevations for breeding)

Short distance migration:

For birds breeding within US/Canada

Long distance migration:

For birds breeding beyond US/Canada
