Treatment effectiveness.

The effects of CORT-implantation on (a) plasma CORT levels during the first, second and third post-treatment sampling sessions (t1, t2 and t3, respectively) and (b) feather mass of replacement middle rectrices in post-molting house sparrows (feather insets are representative for the two treatment groups). Mean ± 1 SE are shown throughout. Sample sizes for CORT levels are 11 at t1, 13 at t2 and 12 at t3.
