1889.] EAMES on Helminthophila pinus and its Alles. 309 
The song of //. chrysoptera consists normally of four notes— 
shree-e-e, zwee, zwee, zwee,—the first, about two notes higher 
than the following three, being slightly prolonged. It is varied 
somewhat at times, with the second note like the first; again it is 
reduced to three, two, or even a single note. The song will im- 
mediately attract attention from its very oddity. By some it is 
considered harsh, but to me it has a soft penetrating quality un- 
excelled, this effect being heightened by the uncertain source of 
the song. 
Seven birds, typical of AZ. lewcobronchial’s, expressed their 
good spirits by precisely the song of the preceding (A. chrysop- 
tera) except in one trifling point. Another, with a bright yellow 
breast-patch, had, in addition, a few original variations of its own. 
Still another, with a close resemblance to AZ. pzxws, repeated 
songs of HZ. chrysoptera only. but they were all harsh and dis- 
agreeable in comparison. This bird was shot almost within a 
stone’s throw of the supposed nesting site of 7. leucobronchialis 
spoken of in ‘The Auk’ (Vol. V, pp. 427-428). A perfectly typical 
bird repeated but one style of song. This surprised me greatly, 
it being precisely the same as the common song of HZ. pénus. I 
heard this many times on two different occasions before shooting 
the bird, and it was always the same. But one more bird, with 
a faint greenish yellow color on the back, a strong patch of yellow 
on the breast, and a wash elsewhere on the under parts, used the 
latter song exclusively. 
The only A. dawrencez I ever knowingly listened to, as before 
mentioned, favored me with its song for nearly two hours, and 
during the several hundred repetitions, it never varied in the 
least particular from the characteristic song of HZ. pzzus, its song 
consisting of two drawling notes, see-e-e-e, zwee-e-e-e-e, with a 
very decided z sound. ‘The first series is somewhat higher pitched 
than the last and hardly as long continued. To this, in HZ. pzvus 
only, is sometimes added a third note of about the same length as 
the first, and very similar. Occasionally the first note only is ut- 
tered. When there are three, the second is sharply and quickly 
given. Another song quite often heard is strikingly similar to 
that of the Nashville Warbler, but still retains enough of its own 
peculiar sound to make identification positive in every case. Of 
several other songs, none of which are commonly heard, one is 
best represented by sweée-e-e, kik, kik, kik, kik.
