Reproduction and Migration

1. Nesting: Birds build nests for laying and incubating eggs.

2. Migration: Many bird species migrate over long distances to breed, feed, or escape harsh weather conditions.

Ecological Importance

Birds play a crucial role in ecosystems as pollinators, seed dispersers, and pest controllers. They also contribute to the balance of food webs and nutrient cycling.

Conservation

Many bird species are threatened by habitat loss, climate change, and human activities. Conservation efforts are essential to protect and preserve bird populations.
