In the recording below you can hear three main species, Woodlark, Meadow Pipit and Great Spotted Woodpecker. The Woodpecker call is the short sharp ‘yip’ that appears on the sonagram as the singular, thick vertical line, reaching around 5kHz. The Meadow Pipit is the continuous ascending call that levels at 7kHz all the way through the recording, which is clear to see on the sonagram. You can also see that the pipit is evenly producing roughly 4 notes per second. Finally, the Woodlark song is the mournful, lower pitched descending sound that can be seen in the sonagram starting slowly at first but gaining pace towards the end of its song. This was recorded up on Slepe Heath (near Arne) this morning, 16/05/14.
