The nightingale (Luscinia megarhynchos) is a small bird. It used to be put in the thrush family Turdidae. Now it is put on the Old World flycatchers, a group often called the chats or chat-thrushes. Its resemblance to thrushes is an example of convergent evolution.
It is a migratory insectivorous species. It breeds in forests and scrubs in Europe and south-west Asia. The distribution is more southerly than the very closely related thrush nightingale Luscinia luscinia. It nests on the ground in or next to dense bushes. It passes the winter southern Africa. Studies have shown that nightingales seem to choose places to breed that meet certain criteria (Wink 1973):
- less than 200 meters above mean sea level
- mean air temperature during the growing season above 14 °C
- more than 20 days/year on which temperatures are above 25 °C
- less than 750mm of rain per year.
- no closed canopy.
The Nightingale is slightly larger than the robin, at around 15-16.5 cm length. It is plain brown above except for the reddish tail. It is buff to white below. Sexes are similar.
Nightingales are named so because they frequently sing at night as well as during the day. The name has been used for well over 1,000 years, being highly recognizable even in its Anglo-Saxon form - 'nihtingale'. It means 'night songstress'. Early writers assumed the female sang; in fact, it is the male.
The song is loud, with an impressive range of whistles, trills and gurgles. Its song is particularly noticeable at night because few other birds are singing. This is why its name (in several languages) includes "night". Only unpaired males sing regularly at night, and nocturnal song is likely to serve attracting a mate. Singing at dawn, during the hour before sunrise, is assumed to be important in defending the bird's territory. Nightingales sing even more loudly in urban or near-urban environments, in order to overcome the background noise. The most characteristic feature of the song is a loud whistling crescendo, absent from the song of thrush nightingale. It has a frog-like alarm call.
