  • Appearance: This bird showcases a dark brown body, with paler gray-brown underparts. Their wings have a distinct blue-violet speculum bordered in white.
  • Diet: They predominantly feed on plant material but will also eat small fish and aquatic insects. Foraging is typically done in shallow water where they will dabble and up-end to reach their food.

  • Diet: Their diet consists mainly of flying insects which they catch in mid-air during their nighttime and twilight hunting forays.
  • Reproduction: Not much is known about their breeding habits, but they are believed to lay their eggs directly on the ground, relying on their camouflage to protect them.

Anna’s Hummingbird

American Flamingo

The American Flamingo is a vibrant, tall wader best known for its brilliant pink coloring and long, sinuous neck.
