 and strikingly different from all other specunens of bird- 

 architecture. The nest is usually placed, not far from the 

 ground,^^ in shrubbery near houses, in piazza-vines, or in 

 cedar trees — particularly those in pastures; also not infre- 

 quently in pines or orchard trees, and less often in shade 

 trees. The eggs average .68 X .48 of an inch, and are light
