Tittel

Long-term consequences of interspecific cross-fostering in the wild

Vitenskapelig sammendrag

The principle objective of this project is to investigate how early experiences contribute to behavioral variation in wild birds. We reciprocally cross-foster great tits to blue tits, and observe the behavior of cross-fostered birds as well as the behavior of their offspring. We hence address both how interspecific cross-fostering influences behavior, and to what extent the resulting learned behavior is transferred to the next generation. The main topics addressed are:• Potential long term fitness costs of interspecific cross-fostering in the wild• Whether the species recognition of parents influences the species recognition of their offspring• Whether parents that have a socially induced low social dominance status (as a consequence of interspecific cross-fostering) have offspring with a low dominance status• Whether male song is affected by interspecific cross-fostering• How the deviant song of cross-fostered males functions in communication with conspecifics and heterospecifics• Species differences in early learning• The appropriateness of interspecific cross-fostering as a method to save endangered bird speciesIn addition, we perform a separate experiment to address the potential use of contextual cues in foraging behavior.
