It's #SwiftAwarenessWeek! To tell a swift from a swallow or martin, look for their dark underside (swallows and martins have pale bellies). Their large wings can appear boomerang-shaped as they soar in groups against the summer sky, calling to each other in high-pitched screams.

It's finally #SwiftAwarenessWeek! We've been saving this picture especially for today, but have been itching to share it after seeing @BBCSpringwatch. The image is taken from Gould's 'Birds of Great Britain', 1873. #Springwatch
