CONSPICUOUSLY BLACK AND WHITE 371 



Tahoe and are not at all difficult to watch. The site 

 chosen for a nest is oftenest in the sheltered woods, 

 where they excavate in the trunk of a dead tree. One 

 that I watched was situated about ten feet from the 

 ground; standing on my saddled horse, I could reach 

 into it but for one obstacle, — the relative size of the 

 door and my hand. I was unwilling to cut away the 

 wood about the door, so contented myself with observ-

 all birds bom in hollow trees. As I sat there just far 

 enough away to see well what was going on, both 

 parents brought insects to the nestlings every ten min- 

 utes. These were usually butterflies, grasshoppers, or 

 dragonflies ; but the male frequently picked up the large 

 ants that swarmed over a log I had broken open, and 

 carried them to the nest. He was much more fearless 

 than the female, — a trait so rare among birds that it 

 deserves especial mention. 



In the same tree with this nest of the Williamson 

 Sapsuckers there were a nest of the pygmy nuthatehes 

 on the other side of the tree and another of a bluebird 

 a little lower down. The nuthatches were, if possible,
