    “…We suggest that biometry can also be a reliable, practical and inexpensive tool to determine the age of nestlings in the field by non-invasive methods. As an example we studied the biometry of wing, culmen, talon, tarsus and body mass of nestling southern Indian Spotted Owlets (Athene brama brama). …”

Nests were either treated against ectoparasites by spraying with pyrethrin or left unsprayed as control nests. …”
