This study analyzes the microstructure and crystallography of palaeognath eggshells across clades to determine evolutionary relationships and ancestral states.

The paper tests how ecological factors influence plumage sexual dichromatism in true thrushes, finding migratory behavior and sympatry with other species increase dichromatism.

This study tests how American robins reject model eggs based on visual acuity and spatial chromatic contrast, finding that larger pattern features increase rejection likelihood.

The paper tests behavioral responses of Whitehead populations to different stimuli and finds that allopatric Whiteheads on Tiritiri Matangi produce alarm calls to cuckoo models, suggesting loss of specific anti-parasitic defenses.

This study shows that reducing corticosterone levels in American robins decreases their likelihood of rejecting foreign eggs, indicating a causal role for glucocorticoids in this host defense behavior.

The paper examines gene expression responses in red-winged blackbirds to conspecific and heterospecific antagonists, finding shared immune-related downregulation and distinct metabolic upregulation in response to conspecifics.

The paper examines how avian diet and foraging ecology influence egg rejection rates in host species against brood parasitism.
