Alcohol resorption and alcohol degradation in the European StarlingSturnus vulgaris

Abstract

All tested blood parameters are within the expected range for birds (Tab. 1). Starlings show a high rate of alcohol resorption. Experimentally ingested (per os) doses of 1, 2 and 3 g/kg ethanol (10 %-solution) were completely absorbed from the digestive tract within at least 30 min. Extraintestinal metabolic alcohol degradation is also very fast. Within 130 min even 3 g/kg ethanol were completely metabolised (blood alcohol values did not exceed 145 mg/l; Tab. 2, Fig. a). Alcoholdehydrogenase (ADH) activity is very high (ca. 14-fold of man) and shows a clear and fast adaptive plasticity in correlation to ingested alcohol concentration (Fig. b). There seems to be a clear pre-adaptation in ADH-activity in birds. We found low values in seed-eating birds and high values in fruiteaters. Under field conditions normal alcohol concentration as found in fermentated fruits and berries are so low, that — in connection with high ADH-activity — birds obviously have no problems to cope with alcohol.
