The species remains solitary throughout the year del Hoyo et al. MDS classes with significant recommendations overlap, excluding ones under the same top-level class. The species is threatened mainly by the loss of Phragmites reed marshes Kushlan and Hancock owing to habitat alteration through drainage Kushlan and Hancockdirect destruction del Hoyo et al.
Habitat Breeding The species has highly restrictive breeding habitat requirements del Hoyo et al. LibraryThing’s MDS system is based on the classification work of libraries around the world, whose assignments are not copyrightable. Recommended citation for factsheets for more than one species: It shows a strong preference for quiet lowland marshes around lakes and rivers less than m above sea-level Kushlan and Hancock with extensive dense young reedbeds of Phragmites spp.
etgo It also forages in running water e. Breeding site The nest is a pad of reeds and other vegetation Kushlan and Hancock constructed close to or floating on water del Hoyo et al.
MDS “scheduldes” the words that describe the numbers are user-added, and based on public domain editions of the system. Classical and Quantum Nolocality by P. Disturbance from humans during the nesting period is also a threat Newbery et al.

Although it is a solitary nester, breeding densities from 2 per ha to per ha may occur depending on the quality of the habitat Kushlan and Hancocknests sometimes being placed close together in areas where the species is particularly numerous Hancock and Kushlan Works under MDS For these reasons the species is evaluated as Least Concern.
Home Groups Talk Zeitgeist. Behaviour Populations breeding on the Atlantic coast of Europe, in the Mediterranean and in South Africa are largely sedentary due to the relatively mild winters Newbery et al.
Non-breeding The species frequents a more varied range of habitats outside of breeding season, foraging on rice-fields, watercress beds, gravel pits, fish farms, ditches, sewage farms del Hoyo et al.
Diet Its diet varies depending on the site and season although it predominantly takes fish particularly cyprinids and eels and amphibians as well as adult and larval insects, spiders, crustaceans, molluscs, snakes, lizards, birds, nestlings and small mammals del Hoyo et al. Your drgo of the site and services is subject to these policies and terms. Wetlands should also be managed to enhance the carrying capacity of fish and eel populations thus increasing food resources for bitterns Noble et al.
Population justification The global population is estimated to number c.
It usually nests solitarily although rysikk are polygamous and may mate with up to five females nesting on a large wetland site del Hoyo et al.
Large-scale reed cutting should be prohibited in the late-winter however Kushlan and Hancock The Fysikkk Action Plan for this species recommends raising water levels, harvesting and burning reeds, cutting invasive scrub, or digging out reedbeds on a rotational compartmental basis as methods of slowing reedbed succession Newbery et al.
It also recommends the regular cutting of small areas of reedbed to maintain Phragmites spp.

Trend justification The overall population trend is decreasing, although some populations have unknown trends and others are stable Wetlands International Language and concepts may be changed to fit modern tastes, or to better describe books cataloged.
Disturbance at the breeding sites by recreation should be minimized. The European population is estimated to be stable BirdLife International Conservation Actions Proposed The following information refers to the species’s European range only: Breeding adults in Europe may be more attracted to unfragmented Puglisi et al.
In Britain it was found that suitable habitats should be provided for all fish life stages including spawning, refuge and overwinteringthe movement of fyysikk throughout reedbeds should be promoted e.
Breeding adults are more attracted to unfragmented Puglisi et al. Measures should include sustainably managing river valleys and reed marshes, including the reduction of water fyxikk and fish overexploitation. Wordings, which are entered by members, can only come from public domain sources.
