Watch: Winter Migration of Birds Begins
When daylight shrinks and there is shortage of food supply at the breeding sites, the birds take the cue and start migrating towards wintering sites in the South. The return journey begins in March or April. While the shorebirds like waders and ducks, and raptors come from Siberia and Russia, birds like the European flycatcher, brown-breasted flycatcher, and barn swallow come from Europe.
