Sept,13, 
A Yast flock of Chinney Swifts suddenly appeared 
over Concord Ri« r this afternoon, dozens sweeping down 
at a time and skimming close over the water, occasionally 
dipping its surface either to seize an insect or to 
drink I could not tell vrhich. All at once there v/as a 
great commotion in their midts and a trim little Palco 
coj^umbarius appeared with one of the Swifts in his 
talons the long wings hanging conspicuously dovm.
