Description

The common little bittern is a small bird, measuring 25 to 40 cm in length and weighing 60 to 150 grams. The wingspan is 40 to 60 cm. These bittern species have a short neck and long bill. The back and crown of male bittern are blackish and the underparts are buff. The wings are blackish with a large white patch.

Habitat

The common little bittern species inhabit a variety of habitats. They occur in freshwater marshes, pools, ponds and lakes surrounded by thick vegetation, desert oases, wooded river margins, flooded grasslands and agricultural fields.

Feeding habits

The common little bittern species feed on insects such as crickets, grasshoppers, caterpillars, spiders and beetles. They also feed on molluscs, crustaceans, fish, frogs, tadpoles, small reptiles and birds.

Breeding

The breeding season of these bittern species is from May to July. The nest is constructed on the emergent vegetation with the help of reeds and twigs. Sometimes the nest is found on bushes and low trees.

Distribution

The subspecies I. m. minutus is distributed in Central and South Europe, North Africa, Siberia, Iran, Pakistan and Northwest India. These subspecies winter in Africa. The subspecies I. m. payesii occurs in Africa ( south of Sahara). The subspecies I. m. podiceps occurs in Madagascar.

Movement Patterns

The common little bittern of the nominate subspecies are migratory and move southwards for wintering. The tropical populations in Africa and Madagascar are resident and make local movements for feeding grounds.

Status and conservation

The global population of these bittern species is yet to be estimated after the recent taxonomic split. They have extremely large range of distribution and large population. These bittern species are least vulnerable. Habitat loss and increasing human activity in the breeding grounds are the potential threat to conservation and management of these species.

The IUCN (International Union for Conservation of Nature) has categorized and evaluated these bittern species species and has listed them as of "Least Concern".
