I am basing the sexing of these
two birds on my observations over the last two years -
The dark head stripes, aspecially
the one under the beak, are much bolder on the male in image
1. They also have a more clean-cut look as though the male has
spent more time preening himself. The stripes on the female,
on the other hand have a softer edge to them and become less
distinct behind the eyes and near the 'neck band' (images 3 and
4).
In image 2, the darker area
at the top of the picture is produced by a neutral density filter,
positioned in front of the camera lens to reduce the effect on
the image of bright light at the box entrance. |
