of June; then they decrease in numbers, 
though their voice is often heard. 
It isa common bird east of the Missis- 
sippi, andis known both by sight and song, 
but I strongly doubt if there are many with- 
in his range who know and would recognize 
this bird by his ‘‘twilight song.”’

[A list of birds observed in northern Mendocino county, 
California, during the spring of 1889. ] 
( Concluded ) 
48.—FPetrochelidon lunifrons.—A very 
abundant bird, breeding in the peak of an 
old barn, thus avoiding the usual trouble 
with rain. 
49.—Chelidon erythrogastra.—Not so 
plentiful as the last—a few pairs only. 
50.— Stelgidopteryx serripennis.* A 
single specimen secured. 
51.— Vireo gilvus.* Abundant, breed- 
ing in the willows and aspens. 
52.—Vireo solitarius cassinit. ess 
abundant than the last. A beautiful nest 
builder. 
53-—Helminthrophila celata lutescens.* 
Rare. 
54.—Dendroica westiva. 
dant. 
55.-—Dendroica audubonit. Abundant 
—birds in high breeding plumage taken in 
the evergreens. 
56.—Dendroica nigrescens.* The most 
abundant Warbler observed. Male birds 
could be heard singing in the larger trees 
every day, and it was quite a common 
matter to take both male and female from 
the same tree. 
57-—Dendroica townsend?. A single 
specimen, in company with the next, was 
secured from a large fir during a shower. 
Fairly abund- 
58.—Dendroica occidentalis. One male 
in fine plumage was secured. 
59.—Geothlypis macgillivrayt. Fairly 
abundant.

Fairly abundant.

uals seen. 
68.—Parus riufescens. 
69.—Psaltriparus minimus. Abun- 
dant-—unfortunately no specimens were 
taken so I cannot be certain that this is not 
californicus. Judging trom the other species 
of birds taken it seems that the chances 
are greater of birds being P. mznzmus from 
here.

Cooper Ornithological Club. 
No August meeting of the Southern 
Division was held, but an interesting meet- 
is booked for September 26. 
The Northern Division met at San Jose 
September 5, with a large attendance. 
It has been decided to take up the prepa- 
ration of a complete annotated list of the 
Land and Water Birds of California. The 
work will be begun by County Committees 
in each county in which the Club is repre- 
sented by members. Information concern- 
ing the work will be sent out during the 
month and Messrs. Bryant and McGregor 
have been appointed a committee to receive 
the county lists when completed. 
Mr. R. H. Beck read a paper on the nest- 
ing of the Western Evening Grosbeak, and 
exhibited the nest and four eggs described 
inthe paper. The article appearsin full 
elsewhere. Mr. R. C. McGregor of Palo 
Alto gave an interesting talk on Panama 
and some of its birds, based on his ex- 
perience as one of a party who was sent to 
Panama last December for the purpose of 
making a collection of the fish. Owing to 
an attack of fever and time spent upon the 
fish Mr. McGregor collected but seventy- 
five specimens, representing thirty-six
