G. Study the arrangement of the feathers; do feathers grow on all parts of the body? a fledgling shows this point well. Push aside the feathers along the line of the ridge of the pigeon's breastbone and examine the skin; do feathers grow here? Look for other un- feathered areas. Note how the feathers overlap. 7. Pick the feathers fron> one side of the pigeon, just to the middle line; lay the bird on the feathered side, and make a drawing, showing (1) the outline of thJ feathers; and (2) the outline of the body within. DISSECTION OF THE PICxEON. Pluck the pigeon before dissecting it; dipping f^ oird liot water makes this easier. 1. Insert a tube into the mouth and inflate the crop, compressing the neck to prevent the escape of the air! Note the shape of the crop. 2. Bt'ginuing at the posterior end of the breastbone, cut HI.
