For those of us (me included ) who are unfamiliar with the 'ins and outs' of a pigeon I thought I would post the following diagrams, identifying the different 'parts' of a pigeon.
Internal Air Sacs Most birds have 9 air sacs: one interclavicular sac two cervical sacs two anterior thoracic sacs two posterior thoracic sacs two abdominal sacs
Functionally, these 9 air sacs can be divided into anterior sacs (interclavicular, cervicals, & anterior thoracics) & posterior sacs (posterior thoracics & abdominals). Air sacs have very thin walls with few blood vessels. So, they do not play a direct role in gas exchange. Rather, they act as a 'bellows' to ventilate the lungs
