Nightingale
Luscinia megarhynchos · also called nightingale, common nightingale
A nightingale is proof that a bird does not need to be beautiful to be famous. It is a small, drab, brown bird that skulks in the thickest bushes and is almost impossible to see well. But the male’s song — a torrent of rich whistles, deep churrs, and rising crescendos delivered through the small hours of a spring night — has made it one of the most written-about animals in Western culture.
Overview
The nightingale, Luscinia megarhynchos, is a plain warm-brown bird with a rusty tail, a little larger than a robin, that lives low in dense scrub, thickets, and coppiced woodland. It feeds on ground invertebrates raked from the leaf litter, adding berries before migration. It is heard far more than seen.
The night song
An unpaired male sings hardest through the middle of the night, when the air is quiet and the sound carries, apparently to reach females migrating overhead in the dark. Once he has a mate, the nighttime singing stops and he sings by day to warn off rival males.
An African bird
Nightingales are in Europe for only about four months. They winter in sub-Saharan West and Central Africa, crossing the Mediterranean and the Sahara twice a year. For most of its life, the bird that fills a May wood with song is living in African scrub.
Status
Least Concern globally but declining, catastrophically so at the range edge: Britain has lost more than 90 percent of its nightingales since the 1960s, as coppicing stopped, scrub was cleared, and rising deer numbers browsed out the low, tangled understorey the bird needs to nest.
Nightingale: common questions
Why does the nightingale sing at night?
Mostly to attract a mate. Male nightingales that have not yet paired sing intensely through the night, when other birds are silent and their song carries without competition, and the target audience is female nightingales migrating overhead in darkness, which may drop down to a singing male. Once a male has attracted a female and paired, the nighttime singing largely stops, and he sings by day instead, which is aimed at defending the territory against other males. So a nightingale heard singing at two in the morning in May is almost certainly a bachelor advertising for a partner.
What does a nightingale look like?
Rather plain, which is part of its mystique. It is a slim bird a little larger than a robin, warm brown above with a slightly rusty-red tail, and pale greyish-buff underneath, with a large dark eye and no bold markings. It stays low in dense cover and is far more often heard than seen. People expecting something spectacular to match the song are usually surprised by how ordinary the bird is, and by how hard it is to get a clear view of one at all.
Where do nightingales go in winter?
To Africa. European nightingales are long-distance migrants that spend the northern winter in a relatively narrow zone of sub-Saharan West and Central Africa, in humid scrub and woodland edge. They leave Europe from July and August, cross the Mediterranean and the Sahara, and return the following April. This means the bird spends only about a third of the year in its European breeding range, and problems anywhere along the route, drought in the Sahel, loss of stopover habitat, or degradation of the wintering grounds, can affect breeding numbers back in Europe.
Why are nightingales disappearing from Britain?
The nightingale needs a very specific habitat, namely dense, low, tangled scrub or the thick regrowth of recently coppiced woodland, with bare ground underneath for feeding. That habitat has become scarce as traditional coppicing stopped and woods grew tall and shaded, as scrub was cleared for farming and development, and, importantly, as deer numbers rose and the animals browsed out the low shrubby layer the birds nest in. Britain sits at the cool northwestern edge of the range, where the species is most marginal, so it has felt these changes first and hardest, losing more than 90 percent of its nightingales since the 1960s.
