Ecology and behavior predict an evolutionary trade-off between song complexity and elaborate plumages in antwrens (Aves, Thamnophilidae).

Evolution; international journal of organic evolution - 1 Oct 2021

Beco Renata, Silveira Luís F, Derryberry Elizabeth P, Bravo Gustavo A

Abstract excerpt

The environment can impose constraints on signal transmission properties such that signals should evolve in predictable directions (Sensory Drive Hypothesis). However, behavioral and ecological factors can limit investment in more than one sensory modality leading to a trade-off in use of different signals (Transfer Hypothesis). In birds, there is mixed evidence for both sensory drive and transfer hypothesis. Few...
