POOR- WILL. 



418. Phalcenoptilus nuttalli. 7% inches. 

 The female of this beautiful little Night- jar differs 

 from the male only in having narrow buffy tips to the 

 outer tail feathers instead of broad white ones. Like all 

 the members of this family these birds are dusk fliers, 

 remaining at rest on the ground in daylight. Their 

 frosted gray plumage harmonizes so perfectly with their 

 surroundings that it is almost impossible to see them. 

 Their eggs are nearly immaculate, but usually show 

 traces of the lavender blotches that mark others of the 

 family. Their call is a mournful "poor-will-ee." They 

 are found from the Plains to the Pacific, but are not 

 common east of the Rockies. 



MERRILL PARAQUE. 



419. Nyctidromus albicollis merrilli. 13 inches. 

 As usual with birds of this family, sexual difference in 

 the plumage occurs chiefly on the tips of the outer tail 

 feathers. These birds are common in the Lower Rio 

 Grande Valley in Texas. Their eggs differ from any of 

 the preceding in having a salmon-colored ground.
