The Keeled skimmer is a dragonfly of heaths and commons with shallow pools. It has a skittish and weak flight, and is on the wing in summer and early autumn.

The common scoter has suffered large declines in the UK, threatening its survival here. Look out for this duck feeding at sea in winter when its numbers are bolstered by migrating birds.

The Black-tailed skimmer is a narrow-bodied dragonfly that can be seen flying low over the bare gravel and mud around flooded gravel pits and reservoirs. It is on the wing from May to August.
