The Indian subcontinent plays host to a number of migratory birds in summers as well as winters. It is estimated that over hundred species of migratory birds fly to India, either in search of feeding grounds or to escape the severe harsh weather conditions of their native habitat.

The different species of birds that had visited India for decades during the winter season were;

  • Siberian Cranes
  • Greater Flamingo
  • Ruff
  • Black winged Stilt
  • Common Teal
  • Common Greenshank
  • Northern Pintail
  • Yellow Wagtail
  • White Wagtail
  • Northern Shoveler
  • Rosy Pelican
  • Gadwall
  • Wood Sandpiper
  • Spotted Sandpiper
  • Eurasian Wigeon
  • Black tailed Godwit
  • Spotted Redshank
  • Starling
  • Bluethroat

Now although the number and variety of birds that migrate has decreased over the last two decades, several foreign species continue to visit National Zoological Park during winters. Previously, almost 5,000 migratory birds spread across more than 10 species used to fly down to the Delhi Zoological Park. But now this number has fallen to an alarming 500-odd birds belonging to hardly five-six species. According to the Zoo’s curator several true migratory birds like Siberian crane, Brahminy duck, Mallard, Red-Crested Pochard and White Stork have not visited the Delhi zoo over the last few years. This decline is due to a number of reasons including atmospheric pollution, hunting by humans, lack of food, global warming etc.

Local migratory birds also turn up at the Delhi Zoo, and this place becomes a treat to watch for bird lovers. October end and November are the months when the birds start arriving, and more birds are estimated to come by January and February.
