Bluethroat

The bluethroat is a migratory insect-eating chat measuring 13–14cm. It is brown above with a strong white eyebrow and a dark tail marked by red basal side patches. Males have a vivid blue throat bordered below by narrow black and broad brick-red bands, sometimes with a central red or white spot. It breeds in wet birch woodland and bushy swamps across the Palearctic, nests low in dense vegetation and migrates to southern Asia and other warmer regions for winter.
