The female Reed Bunting ( Emberiza schoeniclus )
They are about the same size as sparrows, but have longer tails, streaked underparts, and a buff coloured line above the eye.
Females have a brown head, and buff throat throughout the year.
Reed Buntings prefer to roost in large numbers in reed beds or wet and marshy areas, where they can be safe from night predators.
The female makes the nest, and can start to breed as early as May. We saw this one in the wetlands of Alvor, in southern Portugal.
