Academic Press, Amsterdam, pp 45–55. isbn 978-0-12-257305-7 Despite their apparently docile nature, mallards are fascinating to observe. Their prenuptials are often quite aggressive and can involve several males chasing and forcing themselves upon a female. These are usually males that have missed out on pairing up the conventional way and instead choose to hang out in bachelor gangs. Distribution: During the summer, pochards are most likely found along the east coast of England but in the winter they can be seen along almost all of the UK coastline, as well as on large lakes and estuaries inland. Distribution: During the breeding season, they’re most common northwards from the Northumberland coast and off the west coast of Scotland. During the winter, their range expands to include areas along the east and south coasts, parts of the southwest coast and some areas of the Welsh coast.
