Ganges Spectacled Bird ( Zosterops palpebrosa )
|Bonaparte , 1853|
The birds are small and measure only 10 to 14 cm. The color of the upper side is usually gray-brown to olive-green, the belly is yellowish, gray or white. There are some larger types that are also duller in color. The genders do not differ externally. Most species have rings of white feathers around their eyes, which is what led to the German name. They have rounded wings, short legs and a short, pointed beak.
Way of life
All spectacled birds are sociable, outside of the breeding season you can meet them in large flocks. They are sometimes even fought to prevent damage to gardens or plantations. The benefits are often overlooked as they decimate many pests. They are not good fliers and are often loyal to their location. Some species are also migratory birds, such as B. the rust-flank spectacle bird .
They feed on insects , berries and fruits . Your forked tongue is also well suited for absorbing nectar from flowers. They put their short, awl-shaped beak deep into the flower or they drill into the calyx from the outside.
The sexes can hardly be distinguished from the outside, but the males can be clearly recognized by their song during the breeding season. Since the song of many species is considered melodious, they are often kept as cage birds, e.g. B. the Ganges spectacled bird from India and Sri Lanka .
During the breeding season, each pair looks for their own breeding area. The nests are built on forks of branches or in bushes, they consist of fine blades of grass intertwined with cobwebs and other intertwined. The clutch consists of two to five eggs. They have a very short breeding season. The Cape spectacled bird only has to incubate its eggs for a little more than 10 days, which is the shortest known breeding season of all birds (as of 1981).
Genera and species (selection)
The group of spectacled birds is difficult to divide, most species are similar in appearance and way of life. An exception is e.g. B. the black ring spectacle bird living in Borneo at 4000 m altitude , whose eyes are not rimmed white but black. Often very similar forms live close together without mixing, so it is difficult to give information on the number of genera and species.
