Glossary

  • Carrion: the flesh of a dead animal.
  • Cerrado: a vast, tropical woodland-savanna ecosystem of Brazil, the most extensive of its type in South America. Comprising around 21 percent of Brazil’s total land area, the cerrado includes savanna, woodland-savanna and dry forest ecosystems, and has a pronounced dry season.
  • Chaco: an extensive flatland of dry, shrubby woodlands, marshes, gallery forest and palm savanna, occurring in Brazil, Paraguay, Bolivia and northern Argentina.
  • Gizzard: in birds, a thick-walled muscular chamber in which tough food is ground up, sometimes with the aid of ingested pebbles or grit.
  • Inbreeding: the breeding of closely related individuals. An inbred population usually has less genetic variability and this is generally disadvantageous for its long-term survival and success.
  • Incubate: to keep eggs warm so that development is possible.
  • Incubation: the act of incubating eggs, that is, keeping them warm so that development is possible.
  • Pampas: the vast, grassy plains of temperate central and southern South America.
  • Subspecies: a population usually restricted to a geographical area that differs from other populations of the same species, but not to the extent of being classified as a separate species.
  • Territorial: an animal, a pair of animals or a colony that occupies and defends an area.
  • Territory: an area occupied and defended by an animal, a pair of animals or a colony.
