Summary
Use captive breeding to increase or maintain populations of seabirds
A study in 1961–1966 at Warsaw Zoo, Poland (Landowski 1967) reported that a population of Humboldt’s penguins Spheniscus humboldti was maintained in captivity, with occasional successful breeding. Seven penguins were added to an enclosure in 1960, with four more added in 1963. Five of the original penguins were still alive in 1966. The colony laid 20 eggs in five years, but 14 were infertile or destroyed during incubation. Six chicks hatched, but only two survived for longer than two months. The colony was housed in an enclosure with land and pool areas, plus six small nesting holes amongst artificial rocks. Defrosted herring Clupea harengus, and occasionally other fish, were provided as food. Vitamin/mineral supplements were given twice weekly.
