Not all sexual monomorphisms evolve equally: female and male ornamentation in Tyranni passerines

The paper examines female and male ornamentation in Tyranni passerines, finding that ornamentation patterns correlate with sociosexual selection pressures and mating systems.

Habitat specialization structures population divergence and demographic variation in Amazonian floodplain birds

This study links habitat specialization to genetic structure, divergence, and demographic variation in Amazonian floodplain birds using population genomic data.

Song sparrows fail to discriminate between current and historical songs

The study finds that song sparrows do not distinguish between current and historical songs despite detectable changes in song structure over 27-29 years.

Response to geographic variation in song is associated with differential gene expression in the blood of a songbird

The paper examines gene expression changes in song sparrows exposed to local vs. foreign songs, finding differential expression in genes related to song perception, anti-inflammatory responses, and energy metabolism.
