What does carotenoid-dependent coloration tell? Plasma carotenoid level signals immunocompetence and oxidative stress state in birds–a meta-analysis
Mechanisms maintaining honesty of sexual signals are far from resolved, limiting our
understanding of sexual selection and potential important parts of physiology. Carotenoid …

The role of bare parts in avian signaling
Avian plumage has captivated scientists and the public alike for generations and has been a
fundamental study system for research into signal evolution. By contrast, relatively little …

Reduced ectoparasite load, body mass and blood haemolysis in Eurasian kestrels (Falco tinnunculus) along an urban–rural gradient
Urbanisation is proceeding at an alarming rate which forces wildlife to either retreat from
urban areas or cope with novel stressors linked to human presence and activities. For …

Oestradiol reduces female bill colour in a mutually ornamented bird
Carotenoid-based colour signals can be costly to produce and maintain, and trade-offs
between signalling and other fitness traits are expected. In mutually ornamented species …
