Repeated behavioral evolution is associated with targeted convergence of gene expression in cavity-nesting songbirds

The paper investigates convergent evolution in cavity-nesting birds, finding behavioral similarities but limited gene expression convergence across species.

Comparative phylogeography reveals widespread cryptic diversity driven by ecology in Panamanian birds

This study identifies cryptic diversity in Panamanian birds using mitochondrial DNA barcodes and finds ecological factors, not geography, drive speciation.

Nesting strategy shapes territorial aggression but not testosterone: a comparative approach in female and male birds

This study compares territorial aggression and testosterone levels between cavity-nesting and non-cavity-nesting birds, finding increased aggression but no difference in testosterone.

Testosterone secretion varies in a sex- and stage-specific manner: insights on the regulation of competitive traits from a sex-role reversed species

This study examines testosterone secretion in Northern Jacanas, finding similar levels in females and incubating males but higher in copulating males, suggesting physiological regulation of competitive traits differs between sexes and parental roles.

Species and sex divergence in vocalizations between hybridizing role-reversed shorebirds, Northern Jacana (Jacana spinosa) and Wattled Jacana (Jacana jacana)

The paper examines vocal divergence between two hybridizing shorebird species, finding differences in call characteristics that may function as reproductive barriers.
