Fork-tailed Woodnymph

Common name: Fork-tailed Woodnymph
Scientific name: Thalurania furcata
Clades: Trochilini - Emeralds

Fork-tailed Woodnymphs are 9.5 to 12.9 cm (3.7 to 5.1 in) long and weigh 3.6 to 6 g (0.13 to 0.21 oz).

In humid forests, tall second-growth, shaded plantations, or gardens, these solitary hummingbirds spend most of their time. Their favorite food is usually low-growing flowers, especially those in the Rubiaceae family. Male hummingbirds defend flower patches aggressively, while females usually trapline and steal nectar from other hummingbirds' floral territories. A forked tail and dark coloration distinguish males. In contrast to Gray-breasted Sabrewings (Campylopterus largipennis), females have a light gray underside but lack white tail corners.
