==Behavior and ecology==

Wrens vary from highly secretive species such as those found in the genus ''[[Microcerculus]]'' to the highly conspicuous genus ''[[Campylorhynchus]]'', the members of which frequently sing from exposed perches. The family as a whole exhibits a great deal of variation in their behavior. Temperate species generally occur in pairs, but some tropical species may occur in parties of up to 20 birds.<ref name="HBW"/>

Wrens build dome-shaped nests, and may be either [[Monogamy in animals|monogamous]] or [[Animal sexual behaviour#Polygamy|polygamous]], depending on species.<ref name=EoB>{{cite book|editor=Forshaw, Joseph|author=Perrins, C.|year=1991|title=Encyclopaedia of Animals: Birds|publisher=Merehurst Press|location=London|pages=190|isbn=1-85391-186-0}}</ref>

Though little is known about the feeding habits of many of the Neotropical species, wrens are considered primarily [[insectivorous]], eating insects, spiders, and other small [[arthropod]]s.<ref name="HBW"/> Many species also take vegetable matter such as seeds and berries, and some (primarily the larger species) take small frogs and lizards. The Eurasian wren has been recorded wading into shallow water to catch small fish and tadpoles; [[Sumichrast's wren]] and the [[Zapata wren]] take snails; and the [[giant wren]] and [[marsh wren]] have been recorded attacking and eating bird eggs (in the latter species, even eggs of conspecifics).<ref name="HBW"/> A local [[Spanish language|Spanish]] name for the giant wren and [[bicolored wren]] is {{lang|es|chupahuevo}} ('egg-sucker'), but whether the latter actually eats eggs is unclear.<ref name="HBW"/> The [[plain wren]] and [[northern house wren]] sometimes destroy bird eggs, and the [[rufous-and-white wren]] has been recorded killing nestlings, but this is apparently to eliminate potential food competitors rather than to feed on the eggs or nestlings.<ref name="HBW"/> Several species of Neotropical wrens sometimes participate in [[mixed-species flock]]s or [[Ant-follower|follow army ants]], and the Eurasian wren may follow [[European badger|badgers]] to catch prey items disturbed by them.<ref name="HBW"/>
