Comparative analysis of female bubbling calls: Within- and between-species variation among the four species of Cuculus cuckoos

open access: yesAvian Research
In brood-parasitic Cuculus cuckoos, male vocalizations are species-specific and easily distinguishable, whereas female calls are remarkably similar across species, making species identification challenging.
