Now is the season to spot a lot of birds at Lalbagh garden. The lake attracts and houses a few resident (and migratory) birds. One can easily spot the Great Cormorant at the lake or on the nearby tree, either sitting alone or with a group. Observe the Yellow patch on the bird's throat and its long tail. It seems that the birds have a White patch during breeding season. These birds co-exist with Common Egrets, Indian Pond Heron, Waterhen, and other birds, and humans.
The Great Cormorant is known to be used by humans to catch fish. See http://www.theatlantic.com/china/archive/2013/07/catching-fish-using-birds-stunning-images-of-a-dying-art-in-china/277798/.
