where he bursts into a joyous bubbling and warbling, 
calling to his brethren of the tree-tops that, though his 
haunts are changed, his heart is true to the clan. His 
cousin, the Worm-eating Warbler, is tending in his direc- 
tion, living in low bushes and in his habits drifting ever 
marshward, where there may not be sufficient competition

wait for them to appear? So Redstart attempts fly- 
catching and with perfect success. 
But the active blood which surges through his veins 
will not allow him to assume the patient waiting tactics 
of the genuine flycatchers. He may imitate their meth- 
ods of actual capture, bagging his game on the wing, but
