AMERICAN ORNITHOLOGY. 9 



MACGILLIVRAY WARBLER. 



A. O. U. No 680. (Geothlypis tolmei) 



RANGE. 



Western United States from the Rocky Mountains to the Pacific, 



breeding from southern United States north to the southern British 



Provinces. Winters in Central America and Mexico. 



DESCRIPTION. 



This species is very similar to the Mourning Warbler in plumage and 

 size. It can be distinguished at any age and in any plumage by the 

 presence of two white or whitish spots, one above and one below each 

 eye. In the adult males the lores or feathers between the eyes and 

 bill are black, and the breast has black feathers as does the Mourning 

 Warbler but they are never concentrated in a solid patch as in that 

 species. The female Macgillivray Warbler is much duller in color than 

 the male but still retains the gray head and neck but of a very dull 

 color, and the black loral spots are wanting. 



NEST AND EGGS. 



These birds nest usually in small bushes at elevations of two or three 

 feet from the ground, sometimes as high as six feet and again they have 

 been found with the bottom wresting on the leaves. The nests are 

 made of dried grasses and lined with horse hair. Their eggs are 

 usually laid during the latter part of May; they are white spotted and 

 blotched handsomely with brown and gray; size .72x.52. 



HABITS. 



Differing but little in habits from its preceding eastern relatives, this 

 species is found abundantly in moist woodlands and often by the road- 

 side. They are very active and nervous creatures, always dancing 

 about among the underbrush or on the ground and scolding if one is too 

 inquisitive in regard to their family affairs. 



MARYLAND YELLOW^THROAT. 



A. O U. No. 681. (Geothlypis trichas). 



The Maryland Yellow-throats are divided into six sub-species from 

 slight differences in their sizes, intensity of color and geographic dis- 

 tribution. It must be borne in mind that these differences are based 

 upon examinations and measurements of a large series from different
