These introductions describe key attributes, specific sounds and similarities, and provide insights to assist identification and enhance your understanding of each species. Calls Calls for each species are a collection of vocalisations ranging from contact and flight calls, to alarm calls directed at intruders.   It is worth pointing out that labels such as "call" and "song" are merely conventions that have been adopted and are not absolute categories. Some species, such as kingfisher, swift or chough, do not actually have a song that is distinct from the usual calls. In these cases we repeat the vocalisation under both Song and Call areas.   Song Although it is easier to think of melodic and complex vocalisations as song, in reality they are simply more elaborate forms of territorial and display call. For example, the simpler territorial calls of male bitterns and owls and the display calls of male ducks and terns are functionally no different from song and have been categorised as such in this guide.   Song, with its territorial and breeding associations, tends to be seasonal (and mainly in the spring), although a few species, such as robin or wood pigeon, can be heard singing almost all year. For some species, song is virtually their only vocalisation and they are rarely heard outside the breeding season. Where applicable, we have also used the Song area to provide other sounds that you are likely to hear, such as the sounds of a large flock.
