A short note on birds migration |
The mechanisms initiating migratory behavior vary and are not always completely understood. Migration can be triggered by a combination of changes in day length, lower temperatures, changes in food supplies, and genetic predisposition. Different species of birds and even segments of the population within the same species may follow different migratory patterns. |
