Editing Swamp harrier (section)

==Description==
The swamp harrier is largely dark brown, becoming lighter with age, and has a distinct white rump. It hunts by flying slowly, low to the ground, on upswept wings. The body length is {{convert|48|to|62|cm|in|round=0.5|abbr=on}}, and the wingspan is {{convert|118|to|145|cm|ftin|0|abbr=on}}. The recorded weights of adults range from {{convert|580|to|1100|g|lb|abbr=on}}. Females are significantly larger than the males. In New Zealand, 54 males averaged {{convert|640|g|lb|abbr=on}} and 66 females averaged {{convert|870|g|lb|abbr=on}}.{{Citation needed|date=October 2024}} Going on mean weights and linear measurements, the swamp harrier may be by a slight margin the largest extant species of harrier but it is only marginally larger than some other species, like the marsh harriers and the [[Réunion harrier]].<ref>Ferguson-Lees, J., & Christie, D.
