Abstract

One tool for estimating the age of nestling raptors is to measure wing length and apply a regression model (Olsen and Olsen 1987). For calculating nestling age, researchers place a ruler under the unfl attened wing of the nestling and measure from the bend of the wing (carpal joint) to the end of the wing tip (longest digit or primary), then apply the model to predict the nestling's age. Olsen (1997) provided the following model for estimating the age of Southern Boobooks Ninox novaeseelandiae based on captive-bred and raised nestlings: A = (W-0.99) /0.39 (r 2 =0.964, d.f.= 54, P<0.0001) A = days old, W = wing-length in cm
