They swallow the water while their bill tip is still submerged, unlike most birds that bring their bill tip up to swallow.

This short amount of time per bout is achieved by these birds' drinking method.

They feed themselves by around 35 days after hatching, although they are still socially dependent on their parents during this time. They are able to feed themselves around 35 days after hatching, although they are still socially dependent on their parents during this time Young zebra finches fledge about 17 to 18 days after hatching. Chicks fledge about 17-18 days after hatching. The female lays 2-8 white or pale greyish blue eggs which are incubated for 14 to 16 days by both parents. The breeding nest has a small entrance followed by a tunnel, which conceals the contents of the nest, leading to the egg chamber the latter two are separated by a raised lip, preventing eggs from rolling out. This nest helps the birds conserve body heat. The former is dome-shaped, has a large entrance on the side, and lacks an entrance tunnel. Zebra finches build both a roosting and breeding nest. The breeding season usually occurs after rainfall. Nests are usually placed in a thorny shrub or tree, but also in cavities and ledges of commercial buildings. They generally breed in loose colonies of up to 50 nests (although the number of individuals in a colony can be up to about 230 when breeding, and around 350 when not), but they may also nest solitarily. Zebra finches are monogamous and mate for life. Males begin to sing at puberty, while females lack a singing ability. Their song is a few small beeps, leading up to a rhythmic song of varying complexity in males. Their calls can be a loud beep, meep, oi! or a-ha!. Zebra finches are loud and boisterous singers. Insects are usually caught in short flights from lookout perches. In times of scarcity, Zebra finches can use their bill to dig into the ground to find a buried seed. They may also take the head to the ground by jumping up and seizing it with their bill or feet. To do this, they either fly and peck out seeds one at a time, or they perch on a nearby branch. Zebra finches are diurnal and generally forage on the ground but they also eat seeds on the heads of standing grass. During the breeding season, small or medium-sized flocks are common, but outside of the breeding season, they gather in flocks of up to about 500 birds. Zebra finches are social birds they live and forage in flocks, although sometimes they may feed in pairs or singly.
