31. Dendroica occidentalis, (Towns.).—Western Warbler. 
Concerning the occurrence of this Warbler in California, we have no very extended 
information. Dr. Cooper cites the capture of a single specimen at Petaluma, and con¬ 
siders the species a very rare one. 
A single individual, taken near the bead of Tule River in October, was the only one 
I saw. It probably then uses the Rocky Mountains as a highway in its spring and fall 
journeyings to and from higher latitudes to breed. It was quite common at Mount 
Graham, Arizona, in September of 1874, there affecting exclusively the spruce and tir 
woods.

32. Geothlypis trichas, (L.).—Maryland Yellowthroat. 
Apparently not very common, though distributed pretty evenly over the southern 
portion of the State. Notes and habits as at the East. The Macgillivray’s Warbler 
(G. macgillivrayi) was not detected by us, from which I infer its general rarity in the 
southern portion of the State. It, however, occurs here, as it is given from several 
localities by Dr. Cooper; also noted at Nevada City by Mr. Nelson.

33. Icteria virens, (L.), var. longicauda, (Lawr.).—Long-tailed Chat. 
The Chat is wide-spread over Southern California, where, however, we nowhere found 
it abundant. It inhabits the undergrowth and thickets of the streams, from the 
friendly shelter of which it rarely ventures forth. It is one of the noisiest of our small 
birds, and one cannot long remain in the vicinity of a spot inhabited by a pair without 
being made aware of the fact by their noisy outpourings.

34. Myiodioctespusillus, (Wils.), var. pileolatus, (Ridgw.).—Western Blackcap. 
While at Los Angeles, the middle of June, I found this little bird not uncommon in 
the swampy thickets, just the places, in fact, most frequented by it during the migra¬ 
tions. They were in full song, and their short, rather faint ditties were heard as they 
swept in short flights about the extremities of the branches, snapping up their flying 
food. 
The late date at which they were noted seems to preclude the possibility of their 
being mere migrants, though this departure from their usual habits is strange enough, 
when this low altitude be compared with the high mountains they resort to in the 
interior region. 
About the middle of August they became common, moving southward from the 
breeding-grounds in the far north. The bulk of these, however, are the true M. pusillus.
