The Bird and its Haunts. — As a migrant I find Wilson's Warbler 

 usually in bushes bordering woodland waters. At the northern base 

 of Monadnock, Gerald Thayer (M.S.) writes: "This jaunty little War- 

 bler-flycatcher is often common in the spring migration, from the 

 9th to the end of May. It haunts damp alder-copses, orchards, and 

 small deciduous second growth along roadsides, and seems to avoid 

 the upper parts of the mountain and of the surrounding hills.
