Enormous amount of rainfall has developed aquatic vegetation at the Okhla Bird Sanctuary and with this the OBS is all set to host migratory birds, however, the “human interventions” can create disturbance in procreation, according to ornithologists.
Wild life photographer and bird watcher Piyush Sharma said this year, the bird sanctuary has turned into a good habitat for different categories of birds. “All thanks to good rainfall in Delhi and the National Capital Region. OBS is a good hub not for resident and migratory birds and photographers’ delight too. The sanctuary will host good numbers of researchers this year and we are hoping that birds on the verge of extinction, especially migratory birds will come back,” said Sharma.
Ecologists said the Capital hosts more than 300 different bird species. “Including other wetlands in the NCR, the bird sanctuary hosts special migratory species. For instance — Northern Shoveller and their diet include plankton, water insects and snails which they find in good aquatic vegetation,” said Sameer a naturalist and photographer.
“But along this, they require calm environment for breeding. It is very unfortunate that traffic movements, construction activities near wildlife zone have been creating obstructions in breeding which will adversely impact on bird population,” the naturalist added.
The nature has recreated vegetation but feeding grounds are being destroying by the developers,” he added.
The sanctuary is popular for hosting the Greyleg Goose, Bar-headed goose, Ruddy Shelduck, Mallard, Spot-Billed Duck, Common Teal under the category of migratory birds while Common Kingfisher, little Stint, Grey heron and little Egret are resident birds there.
