A winter visitant in the British isles ; is found also in Asia, migrating northwards to breed. In 

 America this bird is not found, its place being supplied by the preceding species. Nothing is 

 known of its nidification.

 the usual sterno-tracheal ones, the second pair are furculo-tracheal, diverging from the tube at the 

 point where it penetrates the cavity of the chest, and inserted between the rami of the os furcatum 

 at the point from whence they branch to unite with the coracoids.
