Endemic bird of the day : Narrow-billed Tody

Abstract

Caribbean Endemic Bird Festival (CEBF) day 119 poster, dedicated to the Narrow-billed Tody. If you’re thinking the Narrow-billed Tody must be the counterpart of the Broad-billed Tody – you’d be right. Hispaniola (shared by Haiti and the Dominican Republic) is the only island with TWO todies and the only island where the todies are not named after their locale. These two todies indeed differ in bill width. They also separate altitudinally. The Broad-billed Tody is found in the lowland broadleaf forests while the Narrow-billed Tody (Todus angustirostris) inhabits the high-elevation cloud and pine forests. Todies, the charismatic faces of the Caribbean, are small green birds with a bright red throat and paler chest. Though similar in coloration to hummingbirds, they are actually more related to kingfishers and motmots. Todies comprise 5 species spread across 4 of the Greater Antilles and are completely endemic to the Caribbean! Besides the narrower bill, how can we distinguish the Narrow-billed Tody? First, check the eye color. Narrow-billed Todies have pale, typically blue eyes rather than the dark brown eyes of Broad-billed Todies. Next, check the breast color, Narrow-billed Todies will have a stark white breast, allowing their yellow and pink side feathers to really pop. In contrast, the Broad-billed Tody has a much streakier yellow-pinkish breast. Finally check the bill. While Narrow-billed Todies do in fact have a narrower bill, the underside of the bill will typically be much darker. And if you really pay close attention, you might even notice that the Broad-billed Tody is overall a much brighter green than the darker, more forest-green of the Narrow-billed Tody. The Narrow-billed Tody is locally known as the Chi-cui, named after its raspy, insect-like vocalization. They can often be heard making this chi-cui sound or a faster lazer call. But unlike the Broad-billed Tody which can make a nonvocal wing noise that sounds similar to running your fingers through a comb, Narrow-billed Todies do not appear to sport this ability. These tiny green birds, weighing in at about 5-6 grams, have a voracious appetite and are seen in a near constant state of foraging. They’ll devour anything- from gooey caterpillars to butterflies, and have even been observed munching on 18 different species of fruits! And with their tiny size they’ve even been found choosing smaller fruits compared to some of Hispaniola’s other avian frugivores. As a complement to the poster, a coloring sheet is included.
