A regular winter visitor to both Fairburn Ings and the North Cave Wetlands. They tend to keep in small groups, and can be quite nervy, if disturbed will practically take off vertically. They fly close together in a tight formation.  Teals are small dabbling ducks. Males have chestnut coloured heads with broad green eye-patches, a spotted chest, grey flanks and a black edged yellow tail. Females are mottled brown. Both show bright green wing patches (speculum) in flight. They are thinly distributed as a breeding species with a preference for northern moors and mires. In winter birds congregate in low-lying wetlands in the south and west of the UK.
