to be favorable for this stream-loving bird. Its absence from the Herbert Brown col- 
lection, now in the University of Arizona Museum, led to looking it up in Swarth’s “Dis- 
tributional list of the Birds of Arizona” (Avifauna No. 10) where the paucity of pub- 
lished records is noted. Thereafter, whenever opportunity offered, | have attempted 
to locate this species. 
My search was first rewarded in June, 1917, when, on a fishing trip to Oak 
Creek Canyon eighteen miles south of Flagstaff, I was delighted to see my old friend 
of former years. At least two individuals were noted, but as they flew back and forth 
up and down stream all during the day of sport they seemed like a dozen. The number 
was not possible to estimate accurately except by laying off the trout fishing, which. 
was even a rarer treat in Arizona than the sight of the Water Ouzels; but I should say | 
there were not more than one or two pairs in the porticn of the stream fished. While 
no nest was discovered, the conditions were so favorable and the birds so evidently at 
home, that I doubt not they breed there. 
I did not personally see this species again until June 13, 1920, when the day was 
spent in Sabino Canyon. During the day a portion of the canyon some two miies in 
length, from eight to ten miles up from the mouth, was explored, and in the course of 
the day two birds, presumably a pair, were seen. No evidence as to their nesting was 
obtained, though from the general non-migratory character of the bird one would as- 
sume that they were at home, and especially at that time of the year. (In Utah the 
Dipper may be seen at any time of the winter along the rushing and consequently un- 
frozen parts of the streams of the Wasatch Mountains). That portion of the Sabino 
explored last June lies between the upper and lower portions which I had previously 
seen, and it is quite possible that in this portion the bird may he a regular resident. I 
this be true then we have a resident pair of Dippers within twenty-five miles of Tucson. 
In the meantime I had talked of this bird to Mr. M. E. Musgrave, Predatory Ani- 
mal Inspector of the Biological Survey for Arizona, suggesting that he be on the lookout 
for it in his more extensive travels about the State. Mr. Musgrave now kindly fur- 
nishes the following Arizona records: : 
“During the year 1918 along Oak Creek; also during the same year along tne 
Black River and its tributaries east of Fort Apache, Arizona; and one on Beaver Creek 
near Montezuma’s Well, north of Camp Verde. In June, 1920, along the White River, 
about ten miles east of Cooley, and a few days later two pairs nesting on a small creek 
known as Trout Creek, which is a tributary of White River and which comes in south- 
east of Cooley about five or six miles; also in the same month several of these birds 
along White River south as far as the Indian Saw Mill, below Cooley about ten miles. 
On February 1, 1921, one on Lime Creek, a tributary to the Verde River, about forty 
miles north of Phoenix.” . 
Taking these records in connection with those gathered by Swarth, it seems rea- 
sonable to assume that the species under consideration occurs rather commonly along 
the mountain streams of the northern and northeastern high plateau and mountain re- 
gion of Arizona, while its occurrence in the ranges of the southern part of the State 
is either spcradic or limited to a few individuals here and there along the most favor- 
able streams, there being at present one record each for the Huachuca, Chiricahua, and 
Santa Catalina mountains. The streams in the Catalinas and Santa Ritas, and probably 
also in the Rincons, are decidedly barren of such aquatic insect nymphs as Plecoptera 
(stone flies) and Ephemerida (may flies), on which the Utah Dippers appeared to 
me to feed largely. These streams are also rather barren of caddis worms (Trichoptera 
larvae) which would seem to offer a good food supply for these birds, but on which 1 
have not actually observed them feeding. 
After the above was written, but before mailing the manuscript, I had occasion 
to again visit Sabino Creek at the point where the two birds were observed last June. 
It was with the keenest pleasure that I again noted on that date, March 22, 1921, the 
presence of two individuals of this species at the precise pool where I first saw one 
in June, 1920. These two kept in close company and are doubtless a resident pair. If 
opportunity permits, an attempt to discover them nesting will be made this season.—
