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 ...

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 ...
Bird vocalization includes both bird calls and bird songs. In non-technical use, bird songs are the bird sounds that are melodious to the human ear. In ornithology and birding , songs (relatively complex vocalizations) are distinguished by function from calls (relatively simple vocalizations).

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).
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.
The male is bright yellow with an orange crown which distinguishes it from most other yellow finches (the exception being the orange-fronted yellow finch).The females are more difficult to identify and are usually just a slightly duller version of the male, but in the southern subspecies S. f. pelzelni they are olive-brown with heavy dark streaks.

The singing of canary Pinchi, containing the words of human speech, was ...
