Dartford Warbler

Curruca undata

Near Threatened

It could become threatened in the near future if current threats go unchecked.

Spotted something wrong?

The Dartford warbler is a small, dark bird with a wine-coloured belly and a long tail that it usually holds cocked, closely tied to low Mediterranean scrub. It is resident across almost all its range, which makes it vulnerable to hard winters and to fire. Spain holds most of the world population. Its decline is caused by the loss of scrub to repeated fires, land clearance and afforestation, and has taken the species into the near-threatened category.

Fun facts

  • GeneralResident and closely tied to scrub; fires hit it hard.
  • Spain holds most of the world population of the species: what happens to the Mediterranean scrub here determines its global future.
  • It is resident and highly sensitive to cold: a particularly hard winter can crash the populations at the northern edge of its range, as happened in England in the 1960s, when it came close to disappearing from the country.
