greater coverts edged and tipt with pale yellow; second row of 

 coverts wholly yellow ; lesser, olive ; tail deep brownish black, 

 lighter on the edges, the three exterior feathers broadly spotted 

 with white. 



The female is destitute of the black mark under the eye ; has 

 a few slight touches of blackish along the sides of the neck; and 

 some faint shades of brownish red on the back. 



The nest of this species is of very neat and delicate workman- 

 ship, being pensile, and generally hung on the fork of a low bush 

 or thicket; it is formed outwardly of green moss, intermixed with 

 rotten bits of wood and caterpillars silk; the inside is lined with 

 extremely fine fibres of grape-vine bark ; and the whole would 

 scarcely weigh a quarter of an ounce. The eggs are white, with 

 a few brown spots at the great end. These birds are migratory, 

 departing for the south in October.
