Study Notes
Avian Migration
- Bird migration is a seasonal movement of birds
- Types of migration include:
- Latitudinal migration: Movement based on latitude
- Altitudinal migration: Movement based on altitude
- Longitudinal migration: Movement based on longitude
- Partial migration: Only some birds migrate
- Erratic migration: Irregular migration patterns
- Seasonal migration: Migration based on seasons
- Climate migration: Migration based on climate changes
- Alimental migration: Migration for food
- Gametic migration: Migration for mating
Modes of Flight in Migration
- Time of flight:
- Diurnal migration: Daytime flight
- Nocturnal migration: Nighttime flight
- Range of migration: Distance covered
- Altitude of flight: Height during migration
- Velocity during migration: Speed during migration
- Routes of migration: Paths taken during migration
Problems of Migration
- Problems of way finding or navigation
- Topographic cues: Using geographical features for navigation
- Experience: Past experiences help birds navigate
- Telluric currents: Using Earth's magnetic field
- Problems of origin of migration
- Problems of stimulus or immediate causes for migration
- Environmental stimuli
