NORTH AMERICAN BIRDS. 383 



680. Geothlypis macgillivrayi (Aud.) [121.] 



Maoeillivr«.y'8 Warliler. 



Hab. Western United States, north to British Columbia; in winter, south through Mexico, and Cen- 

 tral America to Panama. 



Macgillivray's Warbler breeds throughout its United States 

 range — in Colorado, Utah, Montana, Idaho, Washington Territory, 

 Oregon, and in the mountains of California. Mr. A, W. Anthony gives 

 it as a common summer resident of Washington county, Oregon, where 

 it frequents the low, tangled shrubbery, and is found much of the time 

 on the ground. A nest was discovered placed in a hazel at an elevation 

 of one foot. Mr. H. D. Minot obtained a nest at Manitou, Colorado, 

 June 21, which was placed in a scrub-oak five feet above the ground 

 and three feet from a traveled road. Mr, Charles F. Morrison states 

 that this species is one of the most common birds of La Plata county, 

 Colorado, where it nests in juniper bushes, four to six feet up. 



A set of three eggs in Mr. Norris' cabinet was taken May 18, 1884, 

 near Riverside, California. The nest was situated in a small bush near 

 the ground, and was made of dry tules, lined with horse hair. Incuba- 

 tion had begun. The eggs are creamy-white, marked near the larger 

 ends with spots and pen lines (somewhat like an Oriole's e:gg) of clove 

 brown. Their sizes are .74 x. 54, •73X.53, .71X.51. The eggs of this 

 species are three to five in number, usually four, aud average .72X.52. 



681. Geothlypis triclias (Linn.) [122, pari.] 



Maryland Yelloxir-tliroat. 



Hab. Eastern United States, north to Canada and Nova Scotia; in winter. South Atlantic and Gulf 

 States and the West Indies. 



This active little Warbler breeds throughout its United States 

 range. Begins building about the middle of May. The nest is not an 

 easy one to find, being built on the ground, snugly tucked under the 

 foot of bush or tussock of rank grass, and sometimes partly roofed over 

 like the Oven-bird's. The favorite resorts of this Warbler are in low, 

 swampy places or in the shadowy undergrowth of woodland. It resem- 

 bles a wren in its fondness for bush and brier. On approaching such 

 places early in spring one is almost sure to be saluted with its sprightly 

 song, full of energy. My friend, Mr. Thomas M. Earl, has given me 

 the best description of this bird's song that I know of. One evening 

 in May, 1884, he was returning from a day's hunt, and after a rest on 

 an old log, he was about to start on his journey homeward. At this in- 

 stant a little Yellow-throat mounted a small bush, and in quick succes- 

 sion said, tackle me! tackle me! tackle me! 



The eggs of this species are four or five, rarely six in number, 

 clear, crystalline white, but often creamy-white, speckled, chiefly at
