Overview

Demonstrates how incubation mode influences attentiveness patterns in passerine birds, suggesting ecological implications.

Key Points

  • The aim is to understand how ecological and life-history factors influence incubation attentiveness in passerine birds, especially by parental mode.
  • Analyzed data from 466 populations of 307 passerine species
  • Employed Bayesian phylogenetic mixed models
  • Examined interactions between incubation mode, nest structure, and ecological/life-history traits
  • Biparentally incubating species had higher incubation attentiveness than female-only species
  • In biparentally incubating birds, attentiveness decreased with temperature and increased with body mass
  • Female-only incubating birds showed increased attentiveness with absolute latitude
  • Domed-nesting female-only species had lower attentiveness than open- and cavity-nesters
  • Southern Hemisphere female-only species displayed lower attentiveness than those in the Northern Hemisphere
