Cormorants (Phalacrocorax carbo, Pelecaniformes) caught in southern Moravia (Czech Republic) in 1989 - 1990 were examined for arbovirus infections. Isolation experiments were carried out using blood samples of 56 birds. The results were negative. Serological examinations of 31 birds were performed by haemagglutination-inhibition test (HIT) using 5 arboviral antigens of the genera Alphavirus (Sindbis - SIN) and Flavivirus (tick-borne encephalitis - TBE, West Nile - WN) and of the family Bunyaviridae (Tahyna - TAH, Calovo - CVO). Antibodies were detected only to viruses SIN, WN and TAH at different frequencies: 9.7 %, 9.7 % and 22.6 %. The titres ranged from 1 : 20 to 1 : 80
