The Nicobar pigeon is one of the most beautiful of the many species of pigeons or doves. Like all pigeons, the Nicobar pigeon is rather thick-set with a relatively small head, but is heavier than most pigeons the same size. The general coloration is dark green iridescent, with a short white tail. Display plumage of the neck is green with coppery and greenish-blue overtones.
- The Nicobar pigeon feeds on the forest floor, and spends a great deal of time on the ground.
- Like all pigeons and doves, these birds do not sip when drinking, but instead they immerse their bill, sucking up water.
