The waterschlager canary is the most robust example of unilateral syringeal dominance, creating song of which 90% of the syllables are produced by the left syrinx, as determined by recording respiratory pressure and airflow through each side during singing. [2] Waterschlager canaries with left tracheosyringeal nerve cuts are only able to ...
The straightforward approach fails (the canary hits him in the left eye turning it violet). Helped by the parrot's encouragement, he carves a female canary from soap and lures Frankie there; the birds slide down a greased counter, into the sink, and down the drain, but only the soap bird goes through the pipe and down Sylvester's throat.
Birds sing louder and at a higher pitch in urban areas, where there is ambient low-frequency noise. [58] [59] Traffic noise was found to decrease reproductive success in the great tit (Parus major) due to the overlap in acoustic frequency. [60] During the COVID-19 pandemic, reduced traffic noise led to birds in San Francisco singing 30% more ...

It was developed as a cross between another type of finch — the now-endangered Venezuelan red siskin (Spinus cucullatus) — and a yellow domestic canary (Serinus canaria domestica).
Canaries were especially good for this purpose as, unlike finches, doves and mice, they reacted very quickly to carbon monoxide. While a mouse would not have a noticeable reaction until after up to 70 minutes to a carbon monoxide concentration of 0.77% in the air, a canary will fall off its perch after as little as 2.5 minutes from a ...
A bird singing contest is a competition of songbirds, usually caged examples of wild species. Such contests are held in at least 22 countries of the world, and at least 36 different species are used in this way.
The yellow canary is typically 10 cm in length. The adult male colour ranges from almost uniform yellow in the northwest of its range to streaked, olive backed birds in the southeast. The underparts, rump and tail sides are yellow. The female has grey-brown upperparts, black wings with yellow flight feathers, and a pale supercilium. The ...
