Bird Flight
 Some birds can 'glide' on air currents without flapping. Many birds use this method when they are about to land. Some birds can also 'hover' and remain in one place. This method is used by birds of prey such as falcons that are looking for something to eat. Seagulls are also good at 'hovering', particularly if there is a strong breeze. The most expert 'hovering' birds are tiny hummingbirds which can beat their wings both backwards and forwards and can stay quite still in the air while they dip their long beaks into flowers to feed on the sweet nectar.
