 ever, that the little bittern itself considered the attitude 

 a complete protection by adopting it on the approach

 a terrifying ordeal as the sound of the twenty shots I 

 have mentioned. Had the bird frequented the thicker

There were other birds in this country which either 

 by their protective colouring or by their attitudes were 

 rendered inconspicuous and often invisible. Those which

 be expected, birds of the open country, and their colour-
