Alarm calls of nesting Southern House Wrens (Troglodytes musculus)

Mostrar todas las versiones(3)

We examined the structure and characteristics of alarm calls uttered by nesting Southern House Wrens (Troglodytes musculus) during the 2007-2008 breeding seasons. We took multiple structural measures of 221 calls uttered by breeding individuals and used multivariate analyses to classify them. We rec...
