SEMIPALMATED PLOVER 4G9 



range is also a favorable element in its maintenance, and we may even 

 look to an increase in aggregate numbers. It was formerly recognized 

 to a small extent as a game species, and even sometimes shot as a nui- 

 sance by the hunter when stalking game. However, we see no reason 

 why the Killdeer should for a moment be considered a game bird. Its 

 small size and the fact that its flesh is not of the best, being described 

 as fishy or musky in flavor, argue that it had far better be classed 

 among those species which are of marked value to the agriculturalist.
