's warbler is assessed by the IUCN in their Red List of Threatened Species as being of least concern. This is because it has a large total population and an extensive range. The population in Europe is estimated to be between 530 and 800 thousand breeding pairs with a total of 1.6 to 2.4 million individuals. As Europe amounts to about two thirds of its total range, the world population may be in the region of 2.1 to 4.8 million individuals. Numbers of birds may be decreasing somewhat but not to the extent that would

common name of this bird recognises the Italian ornithologist Paolo Savi, the author of "Ornitologia Toscana" (1827–1831) and "Ornitologia Italiana" (1873–1876). In 1821, Savi was given specimens of an unstreaked, dark, rufous-brown warbler which was new to science. He published a full description of the bird in 1824, and it became known by the common name of Savi's warbler. The genus name "Locustella" is from Latin and is a diminutive of "locusta", "grasshopper".

Peru. The IUCN estimates the extent of occurrence, or range, to be 11 500 000 km. This species occurs as a vagrant in Iceland, Ireland, Faeroes, and the UK. The IUCN classifies the black-and-white warbler as Least Concern due to its large range and population size. However, its population is decreasing. Habitat loss and degradation, especially forest fragmentation, are the main factors contributing to the species’ decline. If habitat loss continues, in either or both summer or wintering habitat,

' by the International Union for the Conservation of Nature (IUCN), the IUCN conservation status for the species is 'vulnerable'. The name "Pseudomys" comes from the combined form of the Greek word "pseudes" (meaning "false") and the Latin word "mys" (meaning "mouse"), presumably because of the plains rat's puzzling similarities and differences to "true mice" in the genus "mus". The name "australis" comes from the Latin word "australis" (

Aquatic Warbler Memorandum of Understanding


only 10,200-13,800 males is confined to less than 40 sites in only six countries, with four sites supporting over 80% of the global population. The main threat the aquatic warbler is facing is the loss of habitat due to the decline of traditional, extensive agriculture and overgrowing of the species’ habitat with reeds and bushes or trees. All signatories decide to work closely together to improve the conservation status of the aquatic warbler throughout its breeding, migrating and wintering range. To that end they will, individually or collectively:

Data deficient


A data deficient (DD) species is one which has been categorized by the International Union for Conservation of Nature (IUCN) as offering insufficient information for a proper assessment of conservation status to be made. This does not necessarily indicate that the species has not been extensively studied; but it does indicate that little or no information is available on the abundance and distribution of the species. The IUCN recommends that care be taken to avoid classing species as "data deficient" when the absence of records may indicate dangerously low abundance:
