►SYLVICOLID.K — THE WARBLKliS. 317 



In retriird to its li{il)its, Wilsmi ivjniscnts it as *' loiiiiirkiibly lutivt', nin- 

 iiiii«^', iliiul)inj^, and dartiii",' about ain(»K;j; the opening buds ami lilossoms with 

 extiaoidinarv a^nlity." Audul)on states that in its liabits it is closely allied 

 with the ini.silhm and tlie initmttis, being fond <»t' low thiek coverts in swamps 

 and by the niai'gin of jmjoIs. He also attriluites to it a song of rather pleas- 

 ing notes, enunciated at regular inti'rvals, h)ud enough to l>e heard at the »hs- 

 tance of sixty yards. These ])ecuharities seem to separate it from the true 

 Flycatchers aud to place it among the Warblers.

Habits. Wilson's Ijkiek-Cap is found througliout the United States from 

 ocean to ocean, and as far to the north as Alaska and the Arctic shores, 

 where, however, it is not common. Mr. Dall shot a s})ecinien, May 30, on the 

 Yukon River, where it was breeding, ^fr. Bischoff obtained others with nests 

 and eggs at Sitka, and afterwards found it more abundant at Kodiak. On the 

 Pacitic coast Dr. Suckley found it very abundant in the neighborhood of Fort 

 Steilacoom, where it frec[uente(l thickets and small scrub-oak groves, in its 

 habits resembling the HdmuitJioplHKjcf cehita, flitting about among the dense 

 foliage of bushes and low trees in a busy, restless manner. He describes its 

 cry as a short chit-clud call. In California, Dr. Cooper notes their lirst arrival 

 early in May, and states that they migrate along the coast, up at least to 

 the Straits of Fuca. At Santa Cruz he noted their arrival, in 18GG, about 

 the 2()th of April. They were then gathering materials for a nest, the male 

 bird singing merrily during his employment. As they have been observed 

 in Oregon as early as this, it has been conjectured that some may remain jiU 

 winter among the dense shrubbery of the forests.
