A walk in our wood today produced plenty of springtime action, including one of the quintessential sounds of hilly woodland on the Welsh border - the shivering trill of the Wood Warbler. When they sing, it would seem that various parts of the bird - lower mandible, wings and tail quiver at the same time.This species is one of many sub-Saharan migrants which have arrived back in the UK to breed, drawn here not only by plentiful insect life but, more importantly, a considerably greater day-length than would be the case had they stayed in equatorial Africa. Like other members of the Phylloscopus genus, Wood Warblers are ground-nesters. We keep everything crossed that this bird's announcements will signify breeding intent.
