Editing Jacamar (section)

===Breeding===
The breeding systems of jacamars have not been studied in depth. They are thought to generally be [[monogamy in animals|monogamous]], although a few species are thought to engage in cooperative breeding sometimes, with several adults sharing duties. The family nests in holes either in the soil or in arboreal [[Termite#Mounds|termite mounds]]. Ground-nesting species usually nest in the banks of rivers (or, more recently, roads), although if these are not available they will nest in the soil held by the roots of fallen trees. Bank-nesting jacamars can sometimes be loosely [[bird colony|colonial]]. Clutch sizes are between one and four eggs, and usually more than one. Both parents participate in [[avian incubation|incubation]]. Little is known about the incubation times of most species, but it lasts between 19 and 26 days in the [[rufous-tailed jacamar]]. Chicks are born with down feathers, unique among the piciformes.<ref name ="HBW"/>
