Editing Laughing gull (section)

==Description==
This species is {{convert|36|–|41|cm|in|abbr=on}} long with a {{convert|98|–|110|cm|in|abbr=on}} wingspan and a weight range<ref>{{Cite web |title= Laughing Gull Identification, All About Birds, Cornell Lab of Ornithology |url= https://www.allaboutbirds.org/guide/Laughing_Gull/id|access-date=2020-09-25|website=www.allaboutbirds.org|language=en}}</ref> of {{convert|203|–|371|g|oz}}. The summer adult's body is white apart from the dark grey back and wings and black head. Its wings are much darker grey than all other gulls of similar size except the smaller [[Franklin's gull]], and they have black tips without the white crescent shown by Franklin's. The [[beak]] is long and red. The black hood is mostly lost in winter.

Laughing gulls take three years to reach adult plumage. Immature birds are always darker than most similar-sized gulls other than Franklin's. First-year birds are greyer below and have paler heads than first-year Franklin's, and second-years can be distinguished by the wing pattern and structure.
