Chestnut-mandibled Toucan (Ramphastos swainsonii) or Swainson’s Toucans are the second largest Toucans in the world - being only slightly smaller than the Toco Toucans. Their natural range stretches from Central America to the Northwestern coast of South America. the base of the bicoloured bill is dark red turning into dark maroon color and blackish towards the tip of the lower bill. It is mostly bright yellow above. The male is larger, but otherwise the two sexes look alike – a black body bibbed in bright yellow, a white rump, and red on the underside of its tail feathers. The distinctly shaped and bicolour bill is brown and yellow, huge and curved. Although the Chestnut-mandibled Toucan may appear similar to the Keel-billed Toucan (and is a subspecies of the yellow-throated toucan ) the Chestnut-mandibled has a deeper yellow bib, is somewhat larger, and dominates the Keel-billed at fruiting trees.
