whenever it finds out that it is being watched. There it remains 

 until it is sure no human eye is longer upon it. Then it begins 

 again its spiral ascent or descent of the tree. Its search of the 

 surface of a tree is not so thorough as that of the regular 

 Creepers, but it covers more trees in a day than they do. 



Migratory in its habits, it comes north about April first, 

 nests in June and returns to Florida and farther south in 

 October. Its song is a faint tsee, tsee, tsee.
