Calls and song are only given where a species occurs regularly in the region or where it might be helpful for
identification. Song is of course given for all species breeding in Oman, but many migrants also give at least
occasional bursts of song or sub-song on passage or in winter, even though moving on to breed elsewhere.
Where this is known to be the case in Oman then description of those songs is also given.
A large number of sound guides are now widely available, and given the limitations of phonetic
transcription we strongly recommend that one be purchased. The internet can also be checked for sound
recordings. There is no substitute for learning vocalisations or, if unable to commit them to memory, in
comparing recordings. However, use of the technology to record calls and songs has somewhat lagged
behind digital photography as a means for confirming the identity of a bird. Few of us use sonograms, but
the way forward certainly lies in this field. In our region, for example, the calls of the different subspecies
of Common Chiffchaff Phylloscopus collybita may only be separable by analysis in this way. Indeed, many
recently described new species of birds (and even some mammals) have been first noticed as such on the
basis of their different vocalisations.
There is also, as amply demonstrated by our own species, Homo sapiens, the matter of differing regional
dialects. Songs and calls of bird species commonly found in Western Europe may often sound quite different
in the Middle East. Even within the region, strong intraspecific variations can frequently be noticed.
Habitat
The habitats described in the text are those occupied in the Middle East and this may help in species
identification or at least narrow down the list of possible contenders, or direct you where to look for a
particular species. Habitats occupied by species visiting Oman in winter and/or on passage are detailed
when differing from those utilised in their Middle Eastern breeding grounds.
