An American white pelican (P. erythrorhyncos) was captured in August 1999 in California, USA. The bird was unable to fly away or evade the boat, and showed considerable aggression when captured. Numerous multifocal, 1 mm diameter, yellow masses were observed throughout the lungs and air sacs. The liver was yellow. A 6 cm diameter, firm spherical mass was present in the abdominal cavity, distal to the liver. Aspergillus spp. were cultured from the air sac tissue. Mycobacterium avium was identified from the splenic mass.
