Offspring thermal demands and parental brooding efficiency differ for precocial birds living in contrasting climates
Abstract Background Chicks of precocial birds hatch well-developed and can search actively for food but their homeothermy develops gradually during growth. This makes them dependent on heat provided by parents (“brooding”), which is then traded off against other activities, mainly foraging. Although...
