Sex and body size related variation in call properties in snow petrel (pagodroma nivea).
International audience We studied the physical parameters of calls of the snow petrel, Pagodroma nivea, in relation to body size, sex and individual specificity. Frequency parameters were related to body size in both males and females; larger individuals' voices were pitched ≈2 kHz lower than t...
