The Zebra finch Meadowlark is a relatively common bird of the family Plummeridae of the order Finch, native to the tropical forests of eastern Australia and New Guinea.
The Zebra finch Meadowlark makes good use of natural burrows, or burrows abandoned by other birds, for nesting material, often long and thin grass stems and leaves, such as the soft flakes or ears of grasses. When nesting, the male and female work together, with the male finding suitable nesting material and carrying it to the burrow, while the female builds the nest in the burrow and gradually implants fine grasses, feathers, fibers and other nesting materials. During egg-laying, incubation and brood-rearing, the male still has to carry fine and soft nesting material for the female to repair the nest.
During incubation, when the ambient temperature is above 26 degrees Celsius, they will chirp at the eggs during the later stages of embryonic development, i.e. within 5 days of the hatching date. Nowadays, fetal education is popular among humans, could it be the same for birds?
Many bird embryos can recognize different external sounds as late in their development as a human fetus in the womb, which means that birds are fully equipped with the physiological basis for early fetal education. But we're not birds, so how do we know? Experiments by Australian scientists have shown that even if you're not a bird, you can still discover their secrets.
