and also the more open undergrowth of marshy places. Arrives the 

 last week in April, and remains about two weeks ; returns the first 

 week in September, and stays until the fourth. [149] 



60. (85.) Setophaga ruticilla (Linn.) Siv. Redstart. 



This fiery little fellow, whose flaming colors reflect the ardor within, 

 is chiefly a spring and autumn migrant, but very few individuals re- 

 maining during the summer to breed. It is extremely abundant in 

 the spring, from April 25 to May 20, and no less so in the fall, from 

 September 1 to the 20th of that month, in all woodland and wooded 

 swampy places. The ordinary note is not unlike that of the Summer 

 Warbler, but the actions and whole appearance are unmistakable. Its 

 most characteristic actions are those of running sideways along small 

 twigs, and incessant expanding of the tail. The spring migrations em- 

 brace males in a garb resembling that of the female ; others in a patchy 

 transition state to the perfected colors, and others, again, which have 

 completed their toilet. [152]

61. (86.) Pyranga rubra (Linn.) Vieill. Scarlet Tanager. 



This brilliant creature is chiefly a spring and autumn migrant, but a 

 few breed here. The spring passage is from the 1st to the last week 

 of May ; the autumnal, from the 1st to the 3d week of September. It is 

 found in high, open woodland, and is quite common in the months 

 named. In 1882 it came into the city with numberless other strange 

 guests, which the people took to be exotic birds, and made a beautiful 

 display j for example, a flock of Scarlet Tanagers was seen in one tree 

 in the Smithsonian Grounds, making almost a tropical scene, with hun- 

 dreds of Orioles, Eose-breasted Grosbeaks, Eedstarts, and Warblers 

 scarcely less gay. [154J
