Table 3. Mean (±SD) values for the physical properties of the samples of nest materials taken from the different parts of the nest.

Sample sizes: length of branches and number of lateral branches (mean n—top (11.8), base (6), Cup (6)); Taper (mean n—top (11.7), base (6), Cup (6)); percentage of hollow samples (mean n—top (16.6), base (20), Cup (18.6)).
