Migration is the movement between north and south of the globe, seasonally done by many species of birds.Birds move towards the warmer grounds as a response to change in weather, temperature, wind, habitat for breeding and food availability. It’s a seasonal occurrence, which happens every year at a specific time. The flock of birds goes through a specific flyway, which spans over continents and oceans.These Migrations carries the risk of death for many birds, because of various reasons, like unavailability of food, Hunting by human beings and larger birds, fatigue etc.
A sad reality is that most of the species of migratory birds are declining at an alarming rate. Main reasons behind it are human beings destroying their natural habitat for infrastructure, collisions with large buildings and aeroplanes, hunting, pollution etc.This is the situation for which, now the governments of many countries are coming together to safeguard the natural flyways of these birds.The study of Birds and their nature is called Ornithology.
