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 ...

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 ...
The Forest canary is a small bird with a short, thick beak, measuring 11–13 cm in length and weighing 10-14 g. [7] The male and female are identifiable by their differences in color.
