Aquatic Warbler
Acrocephalus paludicola
Small and slim with a thick, pale eyebrow, a dark crown with a pale central crown stripe, and a heavily striped back reminiscent of the patterning of a snipe. Often perches acrobatically, gripping two stems at once. Breeds in open wet marshlands with scattered bushes or trees, often in areas with sedges; uses reed beds on migration; winters in West Africa, where it uses extensive shallow marshes. Song is fast and chattering. Rare across much of range; population is declining fast due to habitat loss.

保护状况
The aquatic warbler is the rarest and the only internationally threatened passerine bird found in mainland Europe. Apart from a very small remnant population in Western Siberia, its breeding grounds are completely confined to Europe.<p>The main threat the species is facing is the loss/degradation of habitat due to draining of wetlands, the decline of traditional, extensive agriculture and overgrowing of the species' habitat with reeds and bushes or trees. Under the auspices of the Convention on Migratory Species of Wild Animals (CMS), also known as the Bonn Convention, the Memorandum of Understanding (MoU) concerning Conservation Measures for the Aquatic Warbler was concluded and came into effect on 30 April 2003. The MoU covers 22 range States (Belarus, Belgium, Bulgaria, France, Germany, Hungary, Latvia, Lithuania, Luxembourg, Mali, Mauritania, Morocco, the Netherlands, Poland, Portugal, Russian Federation, Senegal, Slovakia, Spain, Switzerland, Ukraine and United Kingdom). As of August 2012, 16 range States have signed the MoU. This instrument provides the basis for governments, NGO's and scientists to work together to save the species and their habitat.<p>Much of the funding for habitat protection for this species has come from the EU's LIFE programme.<p>The main method employed to protect the species from extinction is habitat restoration. Bushes, reeds and trees are cut down. An adequate level of water regulation is achieved through hydraulic equipment installation.<p>In order to protect the bird's offspring, farmers need to select optimal grassland mowing time (as late as 15 of August) and choose environment-friendly mowing technologies. As the late-cut grass isn't suitable for feeding making these measures economically unfavorable, farmers who agree to help out receive state issued compensations. The unusable late-cut grass is taken to processing plants that recycle it into biofuel/grass pellets. <p>Due to small and fragmented populations of aquatic warbler within Lithuania, translocation to the Žuvintas biosphere reserve in Lithuania became necessary as a method to reverse declining genetic diversity in the region.<p>During the species' first translocation In June 2018, the Lithuanian Baltic Environmental Forum (BEF) successfully translocated, raised, and released 49 aquatic warbler chicks from Zvanec Belarus to the Žuvintas biosphere reserve in Lithuania. By the end of the 2019 summer breeding season, 11 (22%) of the translocated birds returned to the Žuvintas biosphere reserve.<p>In the summer of 2019, the BEF successfully translocated, raised, and released an additional 50 birds from Zvanec Belarus to the Žuvintas biosphere reserve.

Black-hooded Thrush
Turdus olivater
Medium-sized thrush of montane forests. Looks large and bulky compared to other thrushes in range; note male’s distinctive black head contrasting with brownish-olive body and yellow bill and legs. Female is similarly patterned but much duller. Found in highland forest and second growth, generally above 800 meters, where it is often the most common thrush. Most reliably seen at fruiting trees, where many individuals may congregate; also often seen at middle levels of forest, where it may take conspicuous perches to assess an observer before flying off. Song is a halting series of phrases, many of them doublets, generally alternating between rich, low notes and high reedy ones; call note is a rich, liquid bark. Male is unlikely to be confused with other species; female could be confused with female Pale-eyed Thrush but is larger, has darker eyes with distinct eyering and a semblance of male’s hooded look.
Recurve-billed Bushbird
Clytoctantes alixii
Unique, medium-sized antbird with a spectacular heavy and markedly upturned bill. Male is slate gray with a black throat, breast, and tail, and black dotted wings. Female is chestnut with a darker tail and buffy spotted wings. Rare, local, and hard to see, typically skulking in the dark understory of second growth and mature forest in foothills, often in areas with dense bamboo. Best found by voice; song a series of short notes accelerating “deeu-deee-dee-dee-eet-et.”
Brown-capped Babbler
Pellorneum fuscocapillus
Small brown babbler, with intense cinnamon underparts and a clear cut blackish brown cap. A terrestrial species occurring on or near the ground in forests, forest edge and nearby scrub and thickets in wooded areas, where typically encountered as pairs. Bold cap and underpart coloration make this distinctive in limited range on Sri Lanka. Repetitive song is a three note whistle “wit-wi-yoo”, ascending at the start and descending at the end. Other more complex warbles are given including an excited series of untidy, downslurred whistles.
