Groove-billed Ani Identification

The Four Keys to ID

• Size & Shape

  A fairly large, disheveled-looking bird with a long, rounded tail and short, rounded wings. It has a tall, heavy bill (though generally smaller than the bill of Smooth-billed Ani). At close range, several grooves in the upper mandible are visible.

  Relative Size

  Larger than a Yellow-billed Cuckoo, smaller than a male Cooper’s Hawk.

  Measurements

  • Both Sexes
• Color Pattern

  Entirely black. The feathers of the upperparts can show some purple or green gloss in optimal light.

• Behavior

  Forages by hopping along on the ground or climbing clumsily through low vegetation. Looks for insects and small vertebrates, especially lizards, and pounces on them with the large bill. Also forages for insects flushing away from groups of cattle or army ant swarms. Occasionally picks ticks from livestock. Usually seen in groups.

• Habitat

  Dense, low vegetation such as shrubs or small trees in arid, open country of lowlands. Nonbreeding birds sometimes move temporarily into wetter habitats such as marshes, especially during droughts.
