Green Heron

Butorides virescens

Green Heron by Alison Sheehey © 1998

Description: 15-22" Adults have a chestnut head and sides. Crown is greenish/black sometimes forming shaggy crest, a white streak down throat and underparts. Bill dark above, yellow below. Short dull yellow legs except male high breeding legs bright orange. Blue-gray back and wings.

Voice: Loud skouwp when flushed from hiding. Also makes a guk, guk, guk call. In flight the call is a softer skouwp or a keeyou.

Habitat: As with all herons and egrets the Green Heron utilizes marsh, river, and small lake habitat. This bird is much more secretive than many of its relatives and it is well camouflaged among riverine vegetation.

Diet: Fish, insects, aquatic, and terrestrial invertebrates.

Nesting: A flat nest made of interwoven sticks normally found near or over water. Two to four pale greenish-blue eggs laid in a usually unlined nest. Normally solitary, though both monogamous parents brood the young.

Range: The solitary Green Heron is found in heavy vegetation lined waterways and marshes in all regions of Kern County. Most commonly found in region SJV.

Status: An uncommon resident that nests in all regions. Kern Audubon considers this species to be threatened in our area due to destruction of habitat.

Formerly known as:

Green-backed Heron

Butorides striatus
