Here are a few reasons why some may perceive the song of tamed canaries as "prettier" or more pleasant:
Selective Breeding: Captive breeding and selective breeding practices can enhance certain desirable traits in canaries, including their song. Breeders may selectively pair birds with superior singing abilities, leading to the development of domesticated strains with more complex and melodious songs.
Consistency and Predictability: Tamed canaries are often exposed to a controlled and stable environment, which may result in more consistent and predictable singing patterns. They may be trained or conditioned to sing in a certain way or at specific times, making their songs more pleasing to human listeners. Wild canaries, on the other hand, are subject to various natural factors that can affect their singing behavior and song quality.
Human Preference: Song preferences are subjective and can vary among individuals and cultures. Some may simply prefer the timbre, pitch, or rhythm of the songs produced by tamed canaries. It is important to note that the beauty and enjoyment of a bird's song are often matters of personal taste.
In summary, while selective breeding and environmental factors may influence the perception of song quality, it is not accurate to make a blanket statement that the wild canary song is not as pretty as the tamed one. Both wild and tamed canaries can produce beautiful and captivating songs, and their appeal often depends on individual preferences and cultural contexts.
