Sparrow bird is a common name for a small group of grain-eating birds that spread across the tropics of the Old World and Australasia. These birds are now incorporated into the Estrildidae tribe, although some also consider this group to be children (Estrildinae), part of the wider Passeridae tribe. Previously, this group of birds was placed in the manyar-manyaran tribe, Ploceidae.
Types of pipits (including bondol and gelatik) love to group, and are often seen moving and searching for food in s considerable hordes. These birds have similar stature and habits, but the colors of the feathers are quite varied. The smallest size is owned by Nesocharis shelleyi whose body length is about 8.3 cm (3.3 inches), although the lightest weight is Estrilda troglodytes (6 g).
While the larger is javanese gelatik, which is 17 cm (6.7 inches) long and weighs 25 g. Most sparrows cannot withstand cold climates and require such warm habitats in tropical regions. But there are also a small number of species adapting to the cold environment in southern Australia. Pipit lays 4-10 grains of eggs, white, which are stored in their nests in the form of grass balls.
