I have lots of favourite birds but having done a little study on these, I have a little more appreciation for this 'simplistic' song and lifestyle of these hardy birds. The name 'chiff-chaff' implies that the bird has 2 distinct notes when it sings, and listening to the bird singing, you would assume that this was right yes? well, not quite, as the bird actually uses 3 notes, sometimes even 4 or 5 depending on the birds repertoire. They use very little notes and manage to switch those notes up so much that they never repeat the same sequence in the same bout. Quite impressive actually..
