Tilopo enano

Identificación

With a total length of 13–15 cm (5.1–5.9 in), it is the shortest pigeon or dove in the world, but as it is thickset, several other species weigh less. Its plumage is overall green, but with contrasting yellow undertail coverts, and narrow bars to the wings. The inner wing-coverts and secondaries are more bluish in color compared to the rest of the body. This bluish-green coloring is most prominent on the scapulars, which are the body feathers that cover the top of the wing when the bird is at rest. The males differ in color and plumage from the female. The males have a dark purple patch on the belly and tend to have a gray patch on both sides of their upper breasts. Both males and females have a yellowish-green beak and purplish-red legs, in addition to a yellow area on their abdomen and undertail coverts. Juvenile fruit doves resemble the coloring of females, but have yellow fringes on most of their plumage. Eventually this yellow fringe will disappear, and the birds will resemble their gender colorings. These fruit doves will often be found in pairs of their own species, and sometimes intermingling with other fruit dove species.<p>Dwarf fruit doves will communicate with each other using a high-pitched, slow, soft, and prolonged up slur. With a one-second pause, the sound is repeated about six times. Their call resembles a “oh-wah” sound.
