sparrow is a common name for a small group of grain-eating birds that spread in the tropics of the Old World and Australasia. These birds are now incorporated into the Estrildidae tribe, though some consider this group to be tribal (Estrildinae), part of the larger Passeridae tribe. [1] Previously, this group of birds was placed in the lotar-war, Ploceidae.
The types of pipes (including bondol and gelatik) are happy to group, and are often seen moving and searching for food in large gangs. 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 largest is the Java gelatik (Padda oryzivora), whose body length is 17 cm (6.7 inches) and weighs 25 g.
Most sparrows can not stand the cold climate and require warm habitats such as in the tropics. But there are also some small types that adapt to cold environments in southern Australia. Pipit spawn 4-10 eggs, white, which is stored in the nest in the form of grass balls.
