%X we analyzed cu and cd liver concentration in adults and fledglings of kelp gull from an urban (coquimbo city) and a wild (p¨¢jaros islet) colony. cu concentration was 15.57 ¡À 0.079 ¦Ìg g-1 dry weight for adults and fledglings of both colonies. adults cd concentration from both colonies was 9.72 ¡À 0.110 ¦Ìg g-1 dw, being 194% of the level considered toxic but in the range for seabirds. in the urban fledglings cd was below the detection level. wild fledgling showed higher concentration of 1.54 ¡À 0.064 ¦Ìg g-1 dw which probably reflects a biomagnification process, because parents kleptoparasite and consume eggs and chicks of other seabirds.
