Viroes. A Kingbird was observed here in battle with 

 a solitary Crow. Ovenbirds were heard on all sides, 

 and two nests were found, both of which had eggs 

 well incubated. 



On proceeding down the valley of the Wanaque 

 River a pair of Yellow-billed Cuckoos were found 

 nesting in a low river birch and their nest contained 

 two well incubated eggs. A pair of Rose-breasted 

 Grosbeaks were also observed here and the male's 

 song often heard, but a careful search failed to re- 

 veal their home. Along the banks of the Wanaque 

 four male Louisiana Water Thrushes were observed, 

 the first of which species have ever come under my 

 personal attention. All of these four were walking 

 about, sandpiper-like, and singing at frequent inter- 

 vals. One male Scarlet Tanager was seen in com- 

 pany with the Grosbeaks and was also singing fre- 

 quently. Here another pair of Chestnut-sided 

 Warblers were observed with young about fifteen 

 days old. A Kingfisher was skillfully driving at this 

 time and brought two small roaches to the surface 

 which he quickly carried off in a northerly direction. 

 A nest of the Black-throated Green Warbler was 

 found here in a high bush huckleberry with a set of 

 four eggs, all of which were well incubated. Both 

 parent birds were about the nest and resented my 

 intrusion by an incessant chirping and angry darts, 

 which in so small a bird were rather ludicrous. A 

 Whippoorwill was flushed along the banks of the 

 Wanaque under a small conifer and rushed off in a 

 very excited manner as I neared him. Indigo Birds,
