SUPPLEMENT TO THE DISTRIBUTIONAL LIST

Archilochus alexandri. Black-chinned Hummingbird. “And recorded, perhaps casu- 
ally, north to Honey Lake and Camp Bidwell”. This strikes one as being a needlessly 
cautious qualification of a species which breeds in Upper Sonoran areas straight through 
to British Columbia. We encountered this species in the Warners July 3 and 9, 1912, 
and at New Albany, Oregon, June 27, 1912. 
Calypte costae. Costa Hummingbird. “Common summer visitant . . . northwest 
to Santa Barbara . . . Rare north of the 35th parallel west of the Sierras”. From the 
circumstance of having encountered this species at La Panza (in central San Luis 
Obispo County) two different seasons, viz., April 21, 1912, and April 20, 1914, I should 
infer that the species might be a breeding bird and of regular occurrence at that sta- 
tion. We saw it also near Pozo, April 30, 1914. 
Stellula calliope. Calliope Hummer. “Summer visitant . . . south ... to the San 
Bernardino Mountains”. On the 26th of May, 1913, I observed the courting evolutions of 
a male Calliope Hummer just north of Idyllwild in the San Jacinto Mountains. Other 
birds were seen June 5th and 6th in the Tahquitz Valley, and there can be little question 
that these were breeding birds. 
Tyrannus tyrannus. Eastern Kingbird. “Rare transient visitant; two records”. 
We encountered this bird at two points on the Modoc-Lassen trip of 1912; one June 15, 
on the north fork of the Pit River about eight miles above Alturas, and the other June 
30, near Eagleville, in the Surprise Valley. Both of these, in all probability, represented 
breeding birds. 
Tyrannus vociferans. Cassin Kingbird. “Fairly common resident . . . northwest 
to Santa Barbara”. This is perhaps based on Willett’s summary 1 : “Winters regularly 
north to Santa Barbara”. In a residence of five years at Santa Barbara I have not seen 
any Kingbirds in winter along this coast. Dr. Evermann, for two years resident at Santa 
Paula, speaks 2 of both species, T. verticalis and T. vociferans. as “summer residents” 
only. Streator, writing of Santa Barbara in 1886, says 3 under Tyrannus verticalis : “A 
very few remain through the winter”. This record would undoubtedly be referable to 
T. vociferans, but the presence of this species in Santa Barbara in winter must be a 
rather irregular occurrence. 
Grinnell’s further statement: “Occurs commonly as a summer visitant, and breed- 
ing, at Paicines, San Benito County”, gives one the impression that such breeding is a 
rare and isolated instance; and this is, in fact, the only reference he makes to its breed- 
ing outside of the “San Diegan district”. As a matter of fact the Cassin Kingbird is 
exceedingly abundant as a breeder throughout the northeastern quarter of San Luis 
Obispo County. It is found also throughout the interior sections of western Santa Bar- 
bara County, and the probabilities are that it enjoys a continuous breeding range from 
western Santa Barbara county, through central and eastern San Luis Obispo, eastern 
Monterey, and San Benito counties to western Merced County. I found the bird west 
of Los Banos, just out of the foothills, on the 21st of May, 1914. 
A correspondent, Mr. Fred Truesdale, living near Shandon in San Luis Obispo 
County, reports the taking of a set of five “Western” Kingbird’s eggs on the 28th of 
March, 1914. The report is trustworthy as to date, and I have, seen the eggs, but I sus- 
pect they are those of T. vociferans. 
Myiarchus cinerascens cinerascens. Ash-throated Flycatcher. “Northernmost rec- 
ord east of the Sierra Nevada: Honey Lake, Lassen County”. We found this bird in a 
stretch of sage and juniper a few miles north of Horse Lake, June 5, 1912. 
Nuttallornis borealis. Olive-sided Flycatcher^ “Breeds west to the coast from 
Monterey County northward”. The Olive-sided Flycatcher breeds regularly on the sea- 
ward slopes of the Santa Ynez Range near Santa Barbara. We took a set of three eggs 
from a live oak tree in Los Canoes Canyon June 5, 1915, at an elevation of about 2600. 
When it is recalled that Bell Sparrows and Black-chinned Sparrows breed locally above 
this point, one may realize how far within the limits of “Upper Sonoran” this record 
really comes. 
Empidonax trail I i trailli. Traill Flycatcher. “Summers in . . . Lower and Upper 
Sonoran . . . rarely low Transition”. “Breeds . . . well into the foothill regions but
