sat singing on some slightly elevated shrub or fence post, I sel- 

 dom saw the females. During migration both sexes are very 

 retiring, keeping well in the shelter of the thickets. 



Song. The ?^Iourning Warbler has a loud, clear, and 

 pleasing song, suggesting that of the Water Thrush. 



Migration and Breeding Range. I obtained a male 

 Mourning Warbler at Williamsport, Pennsylvania, on May 

 1 6, 1876. It passes Rhode Island from the middle to the last 

 of May, and occurs in eastern ^^lassachusetts about the same 

 time. I have seen it here as late as June 2. It breeds from 

 northern New England northward into Canada; southward 

 alone the mountain ranores to the Berkshires, where it is not 

 uncommon in some sections, thence to Pennsylvania and West 

 Virginia. In autumn it passes us in September, but is then 

 much more rare than in spring. It winters in Nicaragua, Cos- 

 ta Rica, and northern South America. 



Genus. LONG-WINGED WARBLERS. Oporornis. 



Siz«s iiiiiforin, 5.50. ("olors, olive above ; yellow beneath. Xo 

 wins* baIl(l^^ or tail spots. Fol(le<l wind's, reacbing- beyond middle 

 of tail. 



Amono- the most robust of the warblers. The winos are 



pointed, the first or second quill being the longest. Bill, stout 



and conical. Feet, large, indicating the ground living habits 



of the species. Keel, high, but the coracoids are shorter than 



in the last two genera. This sternal structure is characteristic 



of birds of strong flight. Two species, both being found with 



us; one, as a migrant, breeding north of us; the other, as an 



accidental visitor from the south.
