Swallows, swift, martins and nightjars

Swifts spend most of their lives flying – even sleeping, eating and drinking – only ever landing to nest. They like to nest in older buildings in small holes in roof spaces.

The tiny, brown-and-white sand martin is a common summer visitor to the UK, nesting in colonies on rivers, lakes and flooded gravel pits. It returns to Africa in winter.

As its name suggests, the house martin can be spotted nesting in the eaves of houses in our towns and villages. Its intricate mud nests take days to build and are often returned to and used in following years.

Look out for the swallow performing great aerial feats as it catches its insect-prey on the wing. You may also see it perching on a wire, or roosting in a reedbed, as it makes its way back to Africa for the winter.

The easiest way to find out if the nocturnal and well-camouflaged nightjar is about is to listen out for its distinctive 'churring' call at dusk. A summer visitor, it is most numerous in southern England.
