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.

Systematics, biogeography and diversification of Scytalopus tapaculos (Rhinocryptidae), an enigmatic radiation of Neotropical montane birds

This study investigates the phylogeny, biogeography, and diversification of Scytalopus tapaculos, finding rapid non-adaptive speciation linked to limited dispersal and landscape barriers.
