A zebra finch will not sing unless there is sufficient testosterone in its blood.

The zebra finch is an important model organism in several fields with unique relevance to human neuroscience.

The grandfather clock chimed eleven, and in its ornate cage a zebra finch fluttered from its perch.

Here, we show the behavioral significance of singing frequency in song development in a songbird, the zebra finch.

In the zebra finch, its protein is 98 percent identical to ours, differing by just eight amino acids.

Insofar as a zebra finch can be said to have a mind, the hormone is a mind-altering drug.

The zebra finch (Taeniopygia guttata) develops a song characterized by vocal variability and crystallizes a defined song pattern as adulthood.

Here, we determined the changes in serum and brain thyroid hormone levels of a passerine songbird species, the zebra finch using radioimmunoassay.

Even a female zebra finch will sing as long as she has been exposed to testosterone early in life and as an adult.

An experiment from 2009 by Fehér and colleagues took newly hatched songbirds of the zebra finch species and raised them in sound proof chambers.

Zebra finches, at least, know how to keep the magic alive.

We prevented zebra finches from singing during the critical period of sensorimotor learning by reversible postural manipulation.

Yet it turns out that female zebra finches find a male sporting red bracelets to be extremely sexy.

Duets were not on their mind; zebra finches don't even duet during courtship, and only males sing songs.

Compared with intact zebra finches, early-deafened zebra finches showed excessively delayed vocal development, but their songs eventually crystallized.

Curious about how zebra finches communicated in nature rather than a lab, Vignal's team put microphones inside nest boxes made for wild birds.
