Rare as the occurrence of this bird is in the British isles, it is not uncommon in some parts of 

 France, Holland, and Germany, and is found also in India and North America. Mons. Temminck 

 informs us in his Manual that it constructs its nest by the sides of rivers and morasses, laying eight 

 or ten white eggs slightly tinged with greenish. 



The form of the tube and inferior larynx in this species will be best understood by consulting 

 the plate. It is acted upon by two pairs of muscles, the first the usual sterno-tracheal ones, the 

 others furculo-tracheal. It differs from that of the foregoing genus in having the tube much more 

 enlarged.
