This little genius, with a bland appearance, looks a bit like a normal sparrow, with tan stripes, and a round and fat body, like a small hairball.
We've heard or heard a lot of birds call good, but only a few birds have reached the level of the North American singing finch. It's not an ordinary chirp, it's really singing. It can sing 10 different tunes. Each tone begins with repeating the same note three times similar to "ding, ding, ding", followed by a particularly beautiful vibrato. If you happen to see it singing, you'll see that its whole little chest is trembling. The whole song sounds very rhythmic, very vivid and tactful.

If you happen to hear it singing in the woods, you will be immersed in it and linger. At this time, I suggest that you do not go to it immediately, but first quietly enjoy the song. This song should only be heard in heaven, and can be heard several times on earth. Certainly not to be missed.

Adult North American singing birds also imitate the intruder's call, sometimes attracting intruders to engage them, causing a war.
