Botaurus is a genus of bitterns, a group of wading birds in the heron family Ardeidae. The genus includes species that were previously placed in the genus Ixobrychus.

Taxonomy

The genus Botaurus was introduced in 1819 by the English naturalist James Francis Stephens.^[1] Stephens did not specify the type species but this was designated as Ardea stellaris Linnaeus (Eurasian bittern) by George Gray in 1840.^[2]^[3] The name Botaurus is Medieval Latin for a bittern. The word combines Latin bos meaning "oxen" (compare butire "to boom") and taurus meaning "bull".^[4] In describing the Eurasian bittern Stephens wrote: "At this period the male makes a singular noise, which is compared with the deep bellowing of a bull, and is continued for about two months: ...".^[1]^[5]

The genus formerly contained fewer species. Molecular genetic studies found that the genus Ixobrychus was paraphyletic with respect to Botaurus.^[6]^[7] To resolve the non-monophyly the genus Ixobrychus was merged into Botaurus which has priority.^[8]^[9]

The bitterns are large chunky, heavily streaked brown birds which breed in large reed beds. Almost uniquely for predatory birds, the female rears the young alone.^[10] They are secretive and well-camouflaged, and despite their size they can be difficult to observe except for occasional flight views. They eat fish, frogs, and similar aquatic life.^[11]

Species

The genus contains 14 species, this includes the New Zealand bittern which is now extinct.^[9]
