INSTINCT is less fallible than reason, but it is not infallible. The 

 migrating instinct successfully guides uncountable legions of frail creatures 

 across abysses of distance from which all but the most hardy of human 

 travellers would shrink. Yet now and then we are called upon to witness 

 its failure, and to record some straggler utterly separated from his kind. 

 A waif Chestnut-sided Warbler, a juvenal male, was picked up in Men- 

 docino County, Sept. 21, 1908, a thousand miles west of any known 

 breeding station of the species. 



If we had not such abundant treasure of our own, we should surely 

 covet the possession of this dainty midget which so abundantly gladdens 

 the brushy hillsides of little old New England.
