AviCA is becoming more and more important for research and preservation of globally endangered species of birds. According to the list of rare species IUCN (http://www.iucnredlist.org/), AviCA has the materials on meetings of 27 species of birds by the categories NT(near threatened), EN(endangered), CR(critically endangered). These are: Dalmatian Pelican (Pelecanus crispus), Lesser White-fronted Goose (Anser erythropus), Red-breasted Goose (Branta ruficollis), Furruginous Duck (Aythya nyroca), Marbled Duck (Marmaronetta angustirostris), White-headed Duck (Oxyura leucocephala), Pallas’s Fish Eagle (Haliaeetus leucoryphus), Egyptian Vulture (Neophron percnopterus), Cinereous Vulture (Aegypius monachus), Pallid Harrier (Circus macrourus), Greater Spotted Eagle (Aquila clanga), Eastern Imperial Eagle (Aquila heliaca), Lesser Kestrel (Falco naumanni), Red-footed Falcon (Falco vespertinus), Saker Falcon (Falco cherrug), Corn Crake (Crex crex), Great Bustard (Otis tarda), Houbara Bustard (Chlamydotis undulate), Little Bustard (Tetrax tetrax), Black-winged Pratincole (Glareola nordmanni), Great Snipe (Gallinago media), Sociable Lapwing (Vanellus gregarious), Black-tailed Godwit (Limosa limosa), Eurasian Curlew (Numenius arquata), Slender-billed Curlew (Numenius tenuirostris), Relict Gull (Larus relictus), European Roller (Coracias garrulus). In October 2008 Uzbekistan joined in the new data base of birds monitoring AviCA (Avis of Central Asia). This data base gives users of whole world the opportunity to input and request data on birds in Central Asia. We already can interest scientists and lovers of birds monitoring. Today about 100 people are users of this base. Among them there are ornithologists, students-biologists and birds lovers. According to the data on February 2010, the data base already has information about 344 monitoring of birds that includes 6268 meetings with 359 species of birds in Central Asia. Unfortunately, the major data are presented only on Uzbekistan and Kazakhstan. On other countries we have now only isolated investigations. But we hope that situation will soon change and AviCA will begin actively work in other countries also. We remind you, that AviCA is placed at the following internet address: http://www.worldbirds.org/v3/centralasia.php or www.avica.uz in Uzbekistan and www.avica.kz in Kazakhstan. Join to us! Contribute to research and preservation of birds!
