For the recent review about the effects of nature sounds on health, the recordings done at parks included a range of sounds, such as thunder, wind, insects, and frogs, as well as ample birdsong. They were recorded in 66 national parks during the summer at dawn.

The recordings were played for participants in lab settings in 11 countries. The most significant outcome linked to the recordings was decreased stress and annoyance. Many participants also reported decreased pain and improved mood, and they performed better on cognitive tests.

Bird song is best developed in the order Passeriformes. Some groups are nearly voiceless, producing only percussive and rhythmic sounds, such as the storks, which clatter their bills. In some manakins (Pipridae), the males have evolved several mechanisms for mechanical sound production, including mechanisms for stridulation not unlike those found in some insects.
The distinction between songs and calls is based upon complexity, length, and context. Songs are longer and more complex and are associated with territory and courtship and mating, while calls tend to serve such functions as alarms or keeping members of a flock in contact.
