PASSERES — OSCINES SYLVICOLIDiE. 41 



Family ALAUDID^E : Larks. 



25. (114.) Eremophila alpestris (Linn.) Boie. (E. cornnta of the original edition.) 



Horned Lark; Shore Lark. 



A winter resident. Arrives November 1 and remains until April. It 

 exclusively inhabits bare, level meadows and open commons, always in 

 flocks of greater or less extent. Before the city extended northward to 

 the boundary line (when there was scarcely a house north of N street 

 in the vicinity of Fourteenth) we used to find the Shore Larks plentifully 

 on the commons we crossed in going to and from college. [82J 



Family MOTACILLID^E : Wagtails. 



Subfamily ANTHINJE : Titlarks. 



26. (52.) Anthus ludovicianus (Gm.) Licit!. Titlark; "Skylark." 



A winter resident; abundant. This species makes its appearance 

 towards the end of October, and remains until April, being always 

 found in restless, straggling flocks, usually of considerable extent, roam- 

 ing in desultory fashion over the open commons, bare meadows, and 

 plowed fields, much such places that the Eremophila frequents. It also 

 has a habit of alighting on the roofs of sheds and houses. We have 

 seen it exposed for sale in large bunches in the markets. [89] 



Family SYLVICOLID^ : Warblers. 



27. (53.) Mniotilta varia (Linn.) Vieill. Black-axo-white Creeper; "Sap- 



sucker." 



A very common summer resident, but more abundant in spring and 

 fall, during the migrations, as the greater number go farther north to

breed. It arrives the first week in April, and is extremely numerous 

 until May. It is generally found in high open woods, scrambling nimbly 

 about the trunks and larger branches of the trees. 



In the original edition we stated that the species breeds in holes in 

 trees. This is a mistake. The nest is built on or near the ground. [91] 



28. (54.) Parula americana (Linn.) Bp. Blue Yellow-backed Warbler. 



This exquisite little bird is a spring and autumn migrant, extremely 

 abundant from April 25 until May 15. Perhaps a few breed with us, as 

 we have found them the first week in August, some time before the War- 

 bler migration sets in. In the autumn the Yellow-back is abundant from
