A study in 38 liver of adults ducks from Jundiaí, state of São Paulo, was developed. After injection of Neoprene latex 650 colored by green and fixation in aqueous 10% formalin, the material was dissected under dental loupe, photographed and sketched. The intra hepatic bile ducts of the left lobe showed up in 76.3% the samples consisting of three collecting ducts bile; and 23.7% of the cases, there was the presence of one collector originated from caudal segment, draining to the hepatic duodenal duct. In theright lobe, in 100% of samples, were four collecting duct segments: cranium medial superficial, cranium medial deep, lateral and caudal (ventral caudal). With regard to biliary extra hepatic in 36 samples (94.7%) it was composed of three ducts visible in hepatic hilum: hepatic duodenal, hepatic cystic and cystic duodenal. In two samples (5.3%) was not observed hepatic cystic duct. The hepatic duodenal duct and cystic duodenal duct in 100% of the samples, they reached the duodenum. In six samples (15.8 %), besides the hepatic cystic duct, the gallbladder was achieved directly by bile collecting ducts of the right lobe. The gallbladder was not achieved by hepatic cystic duct in two samples (5.3 %).
