The swift is a stiff flyer: there appear to be no 

 joints in her wings; she suggests something made of 

 wires or of steel. Yet the air of frolic and of super- 

 abundance of wing-power is more marked with her 

 than with any other of our birds. Her feeding and 

 twig-gathering seem like asides in a life of endless 

 play. Several times both in spring and fall I have 

 seen swifts gather in immense numbers toward night- 

 fall, to take refuge in large unused chimney-stacks. 

 On such occasions they seem to be coming together

 ney-top, a great cloud of them, drifting this way and 

 that, all in high spirits and chippering as they fly. 

 Their numbers constantly increase as other members 

 of the clan come dashing in from all points of the 

 compass. Swifts seem to materialize out of empty 

 air on all sides of the chippering, whirling ring, as

 flight festival go on. The birds must gather in from
