Costly courtship or dishonest display? Intensely displaying sand goby males have lower lipid content

Abstract

Intensely displaying sand goby Pomatoschistus minutus males had lower lipid content, indicating that signalling increased energy expenditure, or that low condition males increased their signalling effort. Display intensity correlated positively with nest‐defence and tended to correlate positively with filial cannibalism.
