So - why do birds sing?
A bird's song is only one type of sound birds make, but it is the most recognizable. Birds have very complex vocalizations, often with more than one tone produced simultaneously, thanks to the specialized syrinx (their equivalent of a voice box) that allows them to create independent sounds in different parts of their trachea. Songs may last 2 to 10 seconds or more and are often repeated in long sequences. A song is generally more musical than other calls, and often incorporates a range of pitches and rhythms into one connected sequence.
In many bird species, only the males sing—they do so conspicuously from high, exposed perches so their song will travel greater distances. As this Whitethroat at Wallsend Rising Sun CP demonstrates...

Learning the various songs and calls is quite a task - but can be done if you get familiar with a few at a time and get them in your 'aural bank'. Of course, hearing them can be a challenge for 'men of a certain age' (like me). My tip? Go birdwatching with a wife who has keen hearing!
