TY  - JOUR
AB  - The status signalling hypothesis aims to explain within-species variation inornamentation by suggesting that some ornaments signal dominance status. Here, we usemultilevel meta-analytic models to challenge the textbook example of this hypothesis, the black bibof male house sparrows (Passer domesticus). We conducted a systematic review, and obtainedprimary data from published and unpublished studies to test whether dominance rank is positivelyassociated with bib size across studies. Contrary to previous studies, the overall effect size (i.e.meta-analytic mean) was small and uncertain. Furthermore, we found several biases in the literaturethat further question the support available for the status signalling hypothesis. We discuss severalexplanations including pleiotropic, population- and context-dependent effects. Our findings call forreconsidering this established textbook example in evolutionary and behavioural ecology, andshould stimulate renewed interest in understanding within-species variation in ornamental traits.
