BIRD'S-NESTING 115

 of the gray and white of its plumage. Some weeks 

 before, the Banker had found down there one of its 

 rare and beautiful nests, like a large hummingbird's 

 nest, lined with down and thatched on the outside 

 with lichens, and fastened to a high bough. 



That day I found the first nest of the prothonotary
