July, 1920 FROM FIELD AND STUDY 155 
On November 22, 1919, a dove was seen in my yard and on the 25th a dead spe- 
cimen was found in an, irrigating canal. I was very much surprised on December 21 to 
tind the half of a small white egg-shell and after considerable search to find a Ground 
Dove brooding a single young in, its nest in a eucalyptus tree. The nest was well built 
for a dove’s nest and being set on some lodged bark was well hidden from view from the 
ground. 
The nesting birds were not disturbed and two weeks later the two old doves and 
the young were discovered feeding on the ground. They soon flew to a tree where the 
young bird was fed by regurgitation, but by one of the parents only. No time was avail- 
able for observation until the following Sunday when the three doves were again seen 
feeding, and later all three flew to an umbrella tree where the young dove was fed by 
both parent doves. The young dove after being fed once hopped onto the old birds 
back then down to the limb on which the old dove was perched; then, when not being 
fed, it extended its wing out over the parent dove and gently tapped the back of its 
parent until it was fed again. It then flew to where the other parent dove was perched, 
where it went through the same actions. Whether this is typical of the behavior of 
young Ground Doves I am unable to say. 
Two Ground Doves were seen pursuing one another through the trees on January 
16, 1920, to all appearances mated. A second nest of this species of dove was found on 
the 22nd of January. This nest contained but one young bird which left the nest the 
next day and has not been seen since. This nest was also in a eucalyptus tree, about 18 
feet from the ground, and was a rebuilt Mourning Dove’s nest. This second nest was 
watched, and on February 14 was seen to have a sitting Ground Dove on it. The two 
eggs it contained were collected the next day and found to have been incubated already 
several days. —JoHn C. Fortiner, Brawley, California, February 29, 1920. 
Calaveras Warbler in San Benito County, Californiaw—The Calaveras Warbler 
(Vermivora ruficapilla gutturalis) is well known in high altitudes along the Sierras in 
California, where it breeds over an extended range, and it is found also on the higher 
mountains north of Lake County and in the migrations on the lowlands in southern 
California. It has seldom been noted, however, on the ocean side of the great valleys or 
along the coast north of Santa Barbara. Two records only in this area between Santa 
Barbara and Lake counties are all that I remember having noticed; one made by Joseph 
Grinnell just back of the Berkeley campus on September 9, 1912, when two individuals 
were seen by him at close range (Condor, xvi, 1914, p. 37), and one for San Benito 
County, where two birds of this species were noted on April 20, 1899, by the late Mr. T. 
E. Slevin and myself, as we were collecting together near Paicines, one of the birds be- 
ing secured by him (Condor, 111, 1901, p. 126). 
This year, on April 17 (1920), in company with Dr. G. Dallas Hanna, of the De- 
partment of Palaeontology, California Academy of Sciences, a number were noted about 
four miles southeast of The Pinnacles, on Bear Valley Creek, as near as we could make 
out from our map. Dr. Hanna and I had motored from Hollister to “The Pinnacles”, a 
rather striking mass of rocks where a great “fault” has occurred, about 30 miles south of 
that town. It was a cold, windy day, and having one long stretch of very badly cut up 
road to negotiate we arrived late at our destination. At one particularly inviting spot on 
Bear Valley Creek we were inclined to stop, but the delay we had experienced decided us 
to push on as we did not then know how much longer it would take us to reach our ob- 
jective point. Reaching this spot about three o’clock in the afternoon on our return, 
however, we concluded that we had time enough to spare for this work and so stopped at 
a place where the little stream ran between a small meadow and a brushy hillside, with 
willows and cottonwoods on its banks—an ideal place for warblers. The first bird that 
caught my eye was a Calaveras Warbler, and further search developed the fact that there 
was quite a number of individuals of this species moving about. The high wind made it 
very difficult to distinguish these warblers from some of the other species among the 
constantly moving leaves and branches of the trees, but we certainly saw twenty-five or 
thirty of them, at least. They were very restless and seemed to be moving up stream in 
a northerly direction, often leaving the trees along the stream to fly up into the brush, 
or vice versa. The difficulty of identifying them quickly in the midst of fluttering
