Arrives on the breeding areas mainly in April (late March in the south, May or even June in the far northeast), returning south in August-September, passage continuing until October, wintering in sub-Saharan Africa. Abundant on passage over most of Europe, the Middle East and North Africa. Birds from the far east of Siberia migrate over 15,000 km to winter in South Africa; in proportion to its size (125 million body lengths!), the longest migration of any bird.

There are 3 subspecies[1]:

  • P. t. trochilus: the most greeny-yellow subspecies; descrived above
  • P. t. acredula: similar to nominate but duller and paler below with less yellow on underparts of juvenile.
  • P. t. yakutensis: drabber still, light grey-brown above and whitish below
  • Eastern Siberia (Taymyr Peninsula to Anadyr River); winters to southern Africa. Occurs as a migrant across central Asia and southeast Europe, and rarely as far west as Britain, but P. t. acredula can appear very similar.

Habitat
