Songs in the understory and colors in the canopy: habitat structure leads to different avian communication strategies in a tropical montane forest

The paper examines how habitat structure influences avian communication strategies, finding support for sensory drive and transfer hypotheses, and partial support for their interaction in a tropical montane forest.

Can net diversification rates account for spatial patterns of species richness?

The paper tests the diversification rate hypothesis by estimating its explanatory power for spatial patterns of species richness in suboscine birds across South America.

Bird songs on the shelf: assessing vocal activity and output using data hidden in sound archives

The paper assesses whether sound archive recordings reflect vocal output and temporal patterns of bird vocal activity, finding significant correlations between archived recordings and field-collected data.

Evolution of bird communication signals: transference between signals mediated by sensory drive

The paper examines how sensory drive influences the transfer of investment between plumage and song traits in New World warblers, finding negative correlations between song complexity and plumage coloration in darker habitats.
