Immune investment is explained by sexual selection and pace-of-life, but not longevity in parrots (Psittaciformes).

PloS one - 1 Jan 2012

Edwards Darryl B

Abstract excerpt

Investment in current reproduction should come at the expense of traits promoting future reproduction, such as immunity and longevity. To date, comparative studies of pace-of-life traits have provided some support for this, with slower paced species having greater immune function. Another means of investment in current reproduction is through secondary sexual characters (SSC). Investment in SSC's is considered...
