Nov., 1921 FROM FIELD AND STUDY 195 
the latter author says, page 38, “The male does not assist in incubation, but supplies its 
mate with food while so engaged, and she rarely leaves the nest after the first egg has 
been laid; at any rate I have invariably found the bird at home if there were any ees 
in the nest”. Major Bendire is referred to in the sentence just previous to the one first 
quoted above. of 
For more light on this subject I have recently looked up far too many authorities 
to mention in this brief article, but the only other reference to the matter of the incu- 
bating habits of this species that I have so far found is in Nuttall’s “Manual of the Or- 
nithology of the United States.and Canada’, 2nd edition, page 720, where it says “incu- 
bation, in which both parents engage, continues for 16 days”. So here are two well 
known ornithologists responsible for absolutely contradictory statements! The matter 
is ‘‘side-stepped” by every other authority that I have consulted. 
Now it happened on June 24, 1921, that Dr. G. Dallas Hanna, of the California Acad- 
emy of Sciences, my brother, John W. Mailliard, and I were lunching at noon time in 
the bed of Nicasio Creek, Marin County, California, at the base of Black Mountain, and 
while so occupied noticed a Belted Kingfisher fly into a hole in the opposite bank. Soon 
after finishing lunch we proceeded to investigate this matter and discovered a nest con- 
taining five eggs, about one-third incubated, with the male bird in the tunnel and ap- 
parently on the nest. This tunnel was about ten feet long and only twelve or fourteen 
inches below the surface of the ground, which was rather sandy and friable, and the 
cavity was easily pried open by means of an old fence picket. 
The bird did not attempt to leave until the nest was almost reached in the up- 
heaving process. As it flew off it was secured for evidence and proved to be the male, 
with the abdominal region partially bare, as if from sitting on the eggs. 
Earlier in the day two kingfishers had been observed flying up and down the 
creek, and shortly before lunch a female had been taken as it perched for a moment on 
a snag about seventy-five yards below the nest, which we had not at that time discovered. 
This female was apparently the other owner, yet showed practically no sign of having 
been incubating, as the plumage upon the abdomen was in a good state of preservation. 
While this matter is not one of great importance it is one of some interest and, 
as part of the life history of a well known bird, might as well be cleared up if possible, 
hence this short paper is written in the hope that some other observer, who may have 
had better opportunities to study the question, may come forward with sufficient evi- 
dence to prove the point one way or the other.—JosepH MAILuIArpD, San Francisco, Cali- 
fornia, August 10, 1921. 
Eastern Kingbird at Mono Lake.—On July 19, 1921, I saw an Eastern Kingbird 
(Tyrannus tyrannus) near Mono Lake, Mono County, California. In Grinnell’s Distribu- 
tional List (1915), there are only two records for the bird from California.—RALPH 
HOFFMANN, Carpenteria, California, September 25, 1921. 
Chronicle of Additions and Eliminations Pertaining to the California State List 
of Birds.—The present note carries the chronicle of the birds of California forward from 
Pacific Coast Avifauna no. 11 (1915) and from my supplementary note in THe Conpor 
of January, 1919 (vol. xxi, pp. 41-42) to October 15, 1921. I have followed the rule of 
letting all definite proposals “ride”, as if the findings set forth were final in every re- 
spect, unless and until someone has brought forward good reasons for doubting the con- 
clusions involved. No attention is here paid to mere changes in names; only the addi- 
tion or subtraction of “concepts” of species or subspecies is considered.
