The … [24], Whilst the European herring gull is fully capable (unlike humans) of consuming seawater, using specialized glands located above the eyes to remove excess salt from the body (which is then excreted in solution through the nostrils and drips from the end of the bill), it drinks fresh water in preference, if available.

Although not always appreciated by mankind due to their droppings and screaming, the herring gull must be regarded as a "natural cleaner", and just as with crows, they help by keeping rats away from the surface in urban environment, not by killing rats, but by eating the potential rat food before the rats get the chance. The male European herring gull is 60–67 cm (24–26 in) long and weighs 1,050–1,525 g (2.315–3.362 lb), while the female is 55–62 cm (22–24 in) and weighs 710–1,100 g (1.57–2.43 lb).
