Bird migration is a very interesting phenomenon of nature, or we can say it is a natural miracle. Bird migration generally happens in winter season when they fly thousands of kilometer to find suitable ecological conditions for their young. When conditions at breeding sites become unfavourable, birds fly to regions where conditions are better.
The timing of migration seems to be controlled primarily by changes in day length. Migrating birds navigate using celestial cues from the sun and stars, the earth's magnetic field, and mental maps.
Here I shoot few migratory birds sometimes back which I am sharing here, hope you would like it.
