Nilgai
Pictures

The nilgai is also known as a blue cow.

This Asian animal was brought to Texas ranches in the 1920s and 1930s for game hunting, but some escaped. There is now a feral population of nilgai in Texas.

Male nilgai have horns, but females, like the one pictured here, do not have horns.

Baby nilgai are called calves.

The biggest of the Asian antelopes, the nilgai can be as much as 4.9 feet high at the shoulder, 6.58 feet long and weigh up to 634 pounds.

Nilgai are so populous in India that they are often considered pests.
