In late May they normally begin singing over an hour before sunrise. They sing the most early in the morning and at evening twilight after sunset. They sing the least around noon. We thought we could figure out approximately how many songs they sing each hour through the day, and add it up. 998 K file.
Robins sing a song that can have long or short pauses between phrases.
We decided for the purposes of this experiment we would count each song as a new one when he made a longer pause. Since a continuous song has few or no pauses, we might think a robin was singing only one song per hour at dawn. We suddenly realized that this is probably the reason ornithologists don't publish the number of robin songs sung in a day. Now it's your turn to be the scientist. Listen to the recordings of robin songs.
