It’s in the spring when the male canaries start to sing. That’s when their androgen levels are high.
The best talker among chatty birds is the mynah.
Birds may be the only vertebrates that continue to produce new brain cells after they are mature. Experts think that’s why a canary has to learn a new mating song every year.
In 1873 it turned suddenly very cold. Historical footnotes mention that the canaries that were supposed to sing at Ulysses S. Grant’s inaugural ball froze to death.
The male canary is the only bird sold with a guarantee to sing. (Female canaries don’t sing.)
The canary wasn’t yellow until man started to manage its breeding process.
Mynahs are part of the starling family. Starlings are among the fastest flying birds. After a few wing beats they do not close their wings, but keep them spread out so as to glide.
In the wild the mynah’s notes vary from low, hoarse chuckles to loud, ringing whistles that carry far. In captivity they often learn to mimic human speech and environmental sounds.
In the wild, mynahs usually travel in pairs.
American crocodiles can be distinguished from American alligators by their longer, more narrow snouts and by their lower teeth, which are visible even when the crocodile’s mouth is closed. [Source]
