Boring nozzle black ear

Boring nozzle black ear

The nozzle-boring-to-ear-black passerine bird is a family of Rhynchocyclidae.

It measures 13-14 cm. One can notice the gray color of the head, where it emphasizes a white area around the eyes and ahead until the nozzle. In adult bird, the eye is light gray, great feature to identify it (the youth, brown eye). The beak is white below and dark above, another important detail in the determination. Clear throat. In the wings, two yellow stripes, with long flight feathers with the clear edge. Yellowish belly, with slightly gray chest. The corner is flashy and after learned, it is easier to locate the bird. Sing the whole year, and July-December issue the call all day. Is active even in the hottest hours of the day, with its high whistle, composed of two or three high notes. In general, the former is shorter, with the following slightly more time consuming, always spaced. There is individual variation in timbre, the spacing and number of notes.

insects that occur between the foliage and branches are displayed and then captured; eventually run short or even acrobatic flights to catch an insect escapes.

Build one of the most interesting nests, joining black fibers of a fungus, Marasmius, found among the roots of trees (the fibers are not woven, despite the appearance). Makes a hanging ball with a side entrance tunnel-shaped facing downwards, longer than the nest itself. Is always on the tip of twigs and tree in the lower or middle, usually inside the forest. Sings very close to the nest. 2 or 3 eggs are placed in a chamber at the top of the nest, with the inlet at the bottom thereof, which is elongated and perpendicular to the ground. Usually it is the female who takes care of the incubation of eggs, although sometimes replaced by the male, for 17 to 19 days. The chicks leave the nest with 22-24 days of life.

Insectivorous the middle part of the dry forest and savanna, occasionally in larger patches of riparian forest in no flood area. Common in typical environments, difficult to observe the camouflage body of an olive color with foliage. Lands in exposed locations (branches and vines), but the behavior of stand still waiting for a prey passing also difficult location. After displayed, is easy to follow, for giving small flights until next perch. Territorial, lives alone or in pairs. It is resident all year in the same location.
