The mortality pattern and histopathologic lesions observed in this case support the use of selective age capture and vitamin supplementation for wild alcid chick collection.Bevier L.R. Microscopic examination of tissues from five of the six birds showed myocardial necrosis and degeneration suggestive of vitamin E deficiency and intestinal protozoa resembling Microsporidia. Clinical signs were nonspecific, and gross necropsies, insecticide toxicology screens, and bacterial cultures were unremarkable.
The birds that died were collected at a young age, weighed 45.4-65.7 g, and had been fed a diet of thawed frozen ocean silversides (Atherinidae) that was not supplemented with vitamins. Six of the 16 puffin chicks died within a 5-day period beginning 2 days after their arrival into quarantine at the zoo. Sixteen horned puffin (Fratercula corniculata) and six parakeet auklet (Cyclorrhynchus psittacula) chicks of various prefledging ages were caught in Alaska and transported to the North Carolina Zoological Park (USA) in August 1995.
