498 LAND BIRDS 



young birds ever have done. There was scarcely a mo- 

 ment when one or the other of the parents was not 

 bending over the nest offering food to the wide-open 

 yellow mouths of the offspring. For several days this 

 was given entirely by regurgitation. Tiie adults had a 

 habit of flying down the canon to their feeding grounds, 

 about a hundred yards away, and I never succeeded in 

 finding out what they brought back. Oftentimes what 

 looked to be the gauzy wings of a dragonfly stuck out 

 on one side of the bill ; at other times the food looked 

 like grasshoppers or crickets, but I cannot be sure what 

 it was. When ten days old, the young were feathered 

 in soft tints of grayish brown, with a hint of blue on 

 head and shoulders. But the constant surveillance had 

 made them uneasy ; as soon as possible they escaped 

 from it by disappearing from the locality the same day 

 that the little ones flew from the nest, and a diligent 

 search failed to discover their whereabouts.
