HABITAT: Marshlands.
DIET: Insects for the most part, some spiders.
NESTING: Nest is a woven structure with a side entrance above water. To protect their territory adults may destroy eggs of other marsh birds, including their own species. Many dummy nests are built. Between four and six beige eggs are laid, incubated by female. Chicks fed by both parents.
DISTRIBUTION: Breeding range includes central Canada and northern half of the USA (except Rockies). Wintering grounds cover Florida, southwest USA and Mexico.

ON PEI: Does not breed on Prince Edward Island, sightings listed as ‘accidental’ so far. See note below on bird vagrancy.
