110 THE CONDOR Vol. XXII 
This kilp is uttered en route from c toa. Hardly has the sound emanated from d 
when the bird may be descried at a, hovering as before and uttering the nine-syllabled 
note already described. Incidentally it may be mentioned that this kilp-note may prove 
very mystifying when heard for the first time, since it is always uttered in rapid transit 
from one place in air to another, but, because it always comes from the same spot in the 
bushes, one is led to assume that the author thereof must be stationary. 
The Anna Hummer went through the performance described, eleven times. Not 
once did the thing vary in any degree or detail that I could detect. The distance from Db 
to d I estimated at 75 feet. 
It may not be amiss to comment briefly on some utterances of this hummingbird 
not necessarily connected with the nuptial flight. The nine-syllabled song is also used 
for ordinary purposes, without other demonstrations, and may be heard when the bird 
is on the wing, or perching. It is subject to irregularities in form, and is not always 
nine-syllabled. Another note is a rapid shaking utterance—chicker-chicker-chicker- 
chicker-chicker—not unlike the trill of the Chipping Sparrow in its more strident and 
untonal phase. This shaking note sometimes follews the kilp-note. Under ordinary 
conditions, i. e., not during the nuptial flight, the nine-syllabled note is sometimes fol- 
lowed by a brisk thip! thip! thip! (th pronounced as in ‘“other’). It is a tiny note, yet 
violent and forced-sounding. The bird also has a sharp smacking ftip-note, like that of 
the Junco and Fox Sparrow. It is sometimes uttered on the wing, in a series: tip, tip, 
lip-tip-tip, etc.—RICHARD HuNT, Museum of Vertebrate Zoology, Berkeley, California, Feb- 
ruary 26, 1920. 
The Northern Bald Eagle a Probable Californian Bird.—The northern form of the 
Bald Eagle (Haliaeetus leucocephalus alascanus), as far as I am aware, has not been 
recorded from California, though it should occur at least as a migrant. The resident 
form in the Upper Sonoran regions of the state is no doubt the Southern Bald Eagle (H. 1. 
leucocephalus), but a specimen in my collection (no. 24854, male adult, Lakeport, Lake 
County; February 2, 1898; Walter Brett, collector), with a wing measurement of 595 mm., 
is large enough to be alascanus. Though the material available is not sufficient to decide 
the point, I have been able to examine two adult females of the southern form, in the 
Dwight collection, one from Fauquier County, Virginia, and one from Safety Harbor, 
Hillsborough County, Florida, having wing measurements respectively of 586 and 565 
mm. The Lakeport male is thus a little larger than either of these southern females, 
and not much smaller than an adult of undetermined sex (though presumably a male), 
in my collection from Douglas Island, Alaska, with a wing measurement of 623 mm. The 
two forms of the Bald Eagle have never been well differentiated. The sexes vary a good 
deal in size among themselves, and the geographical ranges of the two forms are not well 
understood; but an examination of the material available from California will probably 
show the occurrence of both forms in the state.—J. H. Fremine, Toronto, Ontario, Decem- 
ber 15, 1919. 
A New Bird for the Pacific Slope of Southern Californiaa—The Bohemian Waxwing 
(Bombycilla garrula) is a rare bird in California, and there are but two published rec- 
ords for the southern part of the state, I believe. One bird was taken near Victorville 
(Conpor, vil, p. 77), and another near Daggett (Connor, x11, p. 34). There appear to be 
no recorded instances for the Pacific slope of southern California. 
This present winter (1919-20) I have observed numbers of these birds in Clare- 
mont during January and February, and specimens of both sexes were collected on Feb- 
ruary 15, 16,17 and 18. The birds collected were with flocks of Cedar Birds (Bombycilla 
cedrorum), and seemed to be feeding exclusively on pepper berries, with which their 
throats were gorged; one, by actual count, had thirty-nine berries in its throat. To show 
how abundant these birds were here, on February 22 I carefully counted the Bohemian 
Waxwings in a rather large flock. There were over a hundred in a pepper tree, while 
at the same time there were many others sitting in a tall blue gum nearby, so that I am 
safe in saying that there were at least a hundred and fifty of the Bohemian Waxwings 
present at that time. In fact these birds outnumbered the Cedar Waxwings three to one.
