- Field Notes - Friday - June 26 - 1914. 7-9 A.M. Weather - clear and warm. Locality - Canyon Road, University Campus. This was the first trip made by the class. Because of the num- ber (about 15) in the party and their somewhat noisy approach the number of birds studied was less than it might have been otherwise. First heard a warbling vireo, in high oak foliage, near Chemistry Bldg. Next, a willow woodpecker was seen and heard. The peculiar characteristic manner of perching and advancing up a limb, as well as its small size and markings were noted. In vicinity of Senior Women's Hall, the brown towhee, russet backed thrush, and western flycatcher were found. The towhee's pip - (feeding note) its coloration, size and ground foraging

habit were noted. The flycatcher's habit of dipping the tail and constantly turning head from side to side were observed. The somewhat plaintive note of the fly- catcher resembles that of its near relative, the wood-fewee. The russet- backed thrush was seen high up in a dead willow tree. Song and marking, especially the [illegible] grayish breast with dark spots were noted. Near the dairy barns, a pair of plain titmice were seen. It was observed that they usually forage in pairs, and that they in common with all titmice were crested. They are very restless in manner. - Saw a bird on fence, found it to be a California jay in juvenal plumage. In underbrush near small bridge, above dairy barns, found a pair of golden piletolated warblers: to be distin- quished from other warblers, by the black patch on the crown, and the song which is in monotone.

More brown towhees were observed hopping about on the ground under the trees. A bush tit was seen perched on a telephone wire. It was very probably on the wire to get location. A spurred towhee was heard singing in a nearby tree. The song is a monotonous suc- cession of notes- something of a suppressed alarm clock effect. - Found nest of pileated warblers, containing two young, ready to leave nest. Nest was near the ground in a willow shrub. The single rasping note of the wood pewee was heard. Parents feeling? July 1-1914 - 7-9 A.M. Weather - warm, somewhat foggy, very little wind. - About 15-20 students in party. - On campus between East Hall and Senior Women's Hall, song sparrow, warbling vireo, coast jay, purple finch, and brown towhee were heard and seen. The song sparrow, when singing are to be found in trees from 10 to 40 ft. from the ground. The warbling vireo may

be found a little higher up. The coast jays are quite numerous in the eucalyptus, back of the Greek Theatre. They are easily dis- tinguished from the California form by their conspicuous crest as well as by their note. Three notes were heard: (1) a rasping continu- ous note, (2) a discontinuous chattering note, and (3) an imitation of the red-tail-hawk. Heard purple finch in terminal branches of cypress below Theatre. They seem to prefer a lofty perch when singing. Brown Tanagers were seen in eucalyptus grove in numbers Near first bridge on road near S.N. H. saw pair of Sierra juncos, foraging under eucalyptus. White feathers flashed in flight. This species is listed as a winter visitor. Occurrence at this time of year, unusual. The descending trill of a lutecent warbler, was heard just above the bridge. Bush tits were seen in willow brush. Their stinging flight in a scattering flock was observed. Heard their squeaking feeding notes similar to feeding notes of lutescent

Saw a Calif. jay in top of dead willow Tree feeding young. The food call of young as well as the appearance of its juvenile plu- mage were observed. - Observed a pair of Intercent warblers foraging in terminal foliage of a live oak in canyon. Seemed to be feeding young. They hop along, working up the branches, sometimes almost upside down. - Pileated warbler heard near Dairy Barn. Brown towhee also in same locality. Near Swimming Pool, spurred towhee was located in a laurel. Call note similar to that of jay. Saw a purple finch. - Distinguishing characters, purple head and throat, no streaking on breast, amarginate tail. Heard thrasher across canyon on hillside. Several linnets were seen in flight. Their flight is swifter than That of the goldfinches, with less dipping. Heard quail; two calls "the "all's well" and the "come right home". - Spurred towhees seen and heard in live oaks near swim- m ing pool. - The slow, intermittent flight of a brown towhee was observed.

Above pool, in brush in canyon, wren- tit was found, also a song sparrow. The song sparrow is normally a creek-side bird, constantly twitches tail and has a wobbling flight. - Near Hog Serum Lab; perched in a death tree down in canyon, saw a red-shafted flicker. Same locality, black-headed gros-beak. Coloration similar to that of towhee (spurred). The two may be distinguished by song, form of beak and coloration. - Parkman seen seen fluttering about second univ. cottage. No super- ciliary stripe. - Same locality, wren-tit. Buzz- z ing note less staccato than that of g.f. warbler. - A dry hillside brush feeder. Carries tail which is about as long as the body, in a tilted position. - Heard a new call- notes of the sweet-back thrush, similar to quail call. The thrush has several call notes, some of which are detached bits of its song. - From porch of Univ. cottage saw a pair of Anna humming birds, dist. from the Allen by Their larger size and by the greenish tinge of the plumage

An Allen humming bird, two [illegible] warblers and a western flycatcher were also seen here. The barred wings, twitching tail, constantly moving head and small size of the flycatcher were noted. A wren-tit was seen in roadside brush near the swimming pool. - Horizon, - 22 species. Most common form: the brown towhee. Field Notes - July 3 - 1914. Time, 7 to 9 A.M. - Cloudy - no wind. Canyon road. This trip over the same route as the preceding trips was largely a review of bird songs and mannerisms. The same species were encountered in about the same localities. The party was divided into two sections, Dr. Jay- for taking one and conditions for study were more favorable. A female quail was heard calling her young, above swimming pool

to the left of the road. At same place, for first time, we got the song of the wren-tit. From the porch of the first univ. cottage, we saw a russet back eating thimble berries. A song sparrow was heard here.- Above Hog Serum Lab.- a quail's nest containing one egg was found. The nest was little more than a shallow hole in the ground. The egg was white with a few light brown splatched. Above the upper univ. barns, in a patch of thistles, a lazuli bun- ting was seen and heard in perched upon the top of a thistle-stalk. A shrike was seen, at a distance on a fence. Identified by its characteristic bill and coloration. In same place, about 1/2 dozen linnets were seen on the topmost board of the fence. Iden- tified by the reddish coloration of head, throat and breast. - A song sparrow was observed perched in the top of a buckeye tree.

We found that it had three distinct variations in its song. In singing the throat swells out and head is tipped skyward. A vigors were was seen near dairy barns (lower). Differentiated from parkman by presence of superciliary stripe. On return trip, near bridge above S. W. Hall we saw a willow woodpecker, a rather rare campus resident. A pair of sierra junco were also seen. - Near S. W. Hall, parkman wrens were observed foraging about in underbrush and carrying insect food to a nest located in a hole in limb of live-oak. In same locality, we heard wood pewee, lutescent warbler, coast jay, (call note similar to that of red-tail hawk), western flycatcher, warbling vireo, song sparrow, grosbeak and anna hummingbird. Horizon about 26 species.

- Golden Gate Park Trip - July 4-14. Weather calm, warm and bright. In portions of park not sheltered by Trees, a brisk breeze was noticed. The party about twenty in num- ber entered the park at the Knight St Entrance. On lagoon, near this entrance, a coot, a female mallard and two black swans were seen. Most con- spicuous characters noted were (1) The white bill with subterminal brown spot, bill in shape, stout, nearly as long as head. (2) The toes not webbed but with lobate edges. (3) The coloration, whole head and neck blackish, rest of upper parts, seen, plumbeous. This coot was perhaps a prisoner here as the lagoon appeared to me too small to afford the bird the running start necessary to it in starting to fly. Despite the non-webbed toes, the bird appeared to be a good swim- mer not at all handicapped by the pecu- liarity. - The black swan is an exotic form and need not be described here.

There is some doubt as to whether the duck observed was a female mallard. It did not seem much larger than the coat, the adult measurements are 20-25 in. and, 13-16 in. There is a possibility that the mallard was a juvenile of either sex. On lawn near lagoon Nuttall and English sparrows were foraging, the latter predominating in numbers. The Nuttall was easily distinguished by the white markings on the head, also by ground movements. The Nuttall sparrow hops very rapidly, paused and repeats the process. The English sparrow takes slower and longer hops. - Acacia and digitalis were observed in bloom. Scotch broom also in bloom. From the lagoon, the party moved toward the aviary. Russet backed thrushes were heard singing high up in the eucalyptus trees. We heard a California yellow marbler in a clump of shrubbery. The note differs from those of the pileolated and lutescent (?) in being

shreels or higher in pitch (2) in not being so monotonous a repetition and in having a median rather than a terminal variation in tone. - Saw Anna humming birds (1-2?) on wing. Their notes were at first mistaken for the feeding notes of bush-tits. - Spurred Towhee seen and heard. Closely resembles the black- headed grosbeak. Throat of Towhee is black, that of grosbeak orange. Bills are different, " " " being much stouter. A green-backed goldfinch, seen foraging on lawn. A very favorite haunt of this bird. Closely resembles the lutecent warbler, but their ecologic niches are not the same, the warbler not being found so far down, it being more of a hillside habitue. The two forms distinguished at a glance by noting difference in form of bill. Near tennis courts, on lawn many English and Nuttall sparrows were observed. One juvenal Nuttall was observed in process of moult, being without tail feathers.

In deer paddock, Calif. quail and Eng- lish sparrows were seen at a distance. In the pines in moose paddock pine siskins were heard. Did not get a good view of their feeding notes resemble the noise made by winding a watch. A flock of bush-tits was observed here also. — An emu was seen in one of the enclosures. The great size of the bird, its peculiar feathers and the absence of hind- toe were noted. — In the deer paddock a pair of quail with brood of half grown young (8-10) were seen. — In the Aviary — For the most part the species seen here were foreign and need not be especially noted. It may be said in passing that most of the forms from the tropics are very brilliantly colored, while their notes are harsh and unmusical. The short raised toe of the galli- naceous birds was observed on golden and white pheasants. — A bald eagle was studied for chief characte-

isties (v The powerful hooked beak and claw, the white head and neck and the tarsus upper half only, feathered. - Horned and barn owls were also seen. Museum - There a large number of foreign forms were seen. Among the forms of special interest is the ptarmigan, a bird of the arctic whose coloration (white) is protective in a region of snow and whose plumage changes to a mottled grayish upon the melting of the snow, in summer. The roseate spoonbill, the name of which is an indication of its distinguishing character- istic. The night heron (native) with black crown and few long, white crest feathers. The kiwi, somewhat smaller than a goose, which lays an extraordinarily large egg. - The egg of an extinct bird of madagas- car was seen. It was oval in form and had a capacity of two gallons.

Birds of interest in the Japanese tea Garden were the Java sparrow, Japanese stock and Japanese quails minus the long feathers. Stow Lake — A number of water birds were seen here. Two or three coots, same as previously mentioned: a few, scaup ducks of both sexes. Characteristics noted: (1) short wide bluish bill, (2) head greenish black, shoulders rump & chest black. Female — prevailing color brown- ish. On the shore near the water's edge a pair of brewer blackbirds were seen. The male, bluish black, the female dark brownish, without markings. — A single baldpate duck was identified by the bill, blue with black tip, The white crown with sides of head bearing metallic green patches, neck and head region below green patches, buff with dark specks. — A single ruddy duck was identified by its prevailing chestnut color;

and black head with white cheek patches. The most numerous ducks were the mallards - more numerous than all the other forms together. They were in summer plumage, males and females being very much alike. Two large ducks were not identified. Across the lake near the waters edge a number of pelicans were seen. Crossing the bay two species of gulls were observed, - Larus occidentalis (western gull) and Larus heermani (Heerman gull). The first is slightly larger than the second and may be distinguished from it by color ation as seen in flight. The mantle is a dark slate color while in the case of the Heerman, the bill is bright red and the head and upper neck are white. The horizon was in all 30-35 species.

- Notes on Mammals- In deer paddock; saw young fawn. Spotted coat of young fawn noted - probably serves to break up the outline of the creature and in a proper setting serve to hide it from its enemies. - In the moose paddock, a bull moose, several cows and a young calf were observed. The horns of the bull were in the "velvet." The horns of all the cervidae are lost or cast annually and new ones grown. Each new set of antlers is larger and more complex than the preceding. The young moose is provided with stilt-like legs by means of which it may escape from pursuing enemies. The brown bear (Ursus arctos) is a form which is found from Vancouver northward to Alaska. This species sometimes exceeds the grizzly in size.

Two phases of the black bear were seen. Difference in moult caused difference in color — A number of bison were seen. They presented a rather uncouth appearance, in their half-moulted coats. It was noted that bison do not have upper front teeth.

Sunday - July 5 - 1914 - 8 A.M. - 2 P.M. Locality - Campus to Grizzly and Bald Peaks. - Weather foggy until 9:30. No wind until upper slopes were reached. These found a brisk breeze! Two in party. - Condition of vegetation - found tar-weed, dog-fennel, sycamore, rodium, convolvulus, elder-berry, brassica campestris, and escholtzia in bloom, dandelion and thistle in seed. Western flycatcher heard in upper foliage of tree near Harmon Gym. Saw about a dozen linnets on wires and roof at Budd Hall. Great num- bers of English sparrows were encoun- tered in streets, vacant lots and on campus. - In canyon near East Hall, a pair of Santa Cruz song sparrows were observed foraging in the low brush near the stream bed. Saw brown towhee on ground near Chemistry Bldg. As usual heard purple finch in top of conifer below

L.W. Hall. This seems to a favorite station. Later saw the bird. They are not of a restless disposition apparently and sing for a considerable time without change of position. - Spurred towhee seen and heard above) L.W. Hall. From same station heard coast joy, song sparrow, western warbling vireo and the aberrant spurred towhee. This towhee was found in company with a young brown towhee about which it seemed to be quite solicitous. - Parkman wrens (2) were seen in vicinity of nest. Did not enter it while under observation. - California jay foraging on ground above L.W. Hall. - Heard note of wood peewee and finally located the bird. In vicinity of dairy barns, heard song sparrow, golden finch, and lutescent warblers, and 'russet-backed' thrush. - In willow shrub, in canyon above hopserum lab. saw and heard lazuli bunting. - On

Grizzly Peak, saw two small hawks at a distance, - probably Falco spar- verius. They were evidently feeding on insects. They would soar at some distance from the ground, then swoop down and skim along surface. Sometimes they would head into the wind and beating wings rapidly maintain a stationary position, then swoop down. Some of the raptors habitually forage in pair, whether this is the case with the sparrow hawk I do not know! - In the dense growth of live oak, etc. in canyon between Grizzly and Baldy, heard California Thrasher. From its song, we picked out the notes of the hawk, jay robin. - Heard and saw a few sturnella neglecta. - Between Grizzly and Bigle among the recently planted pines we found finches in large num- ber (in almost total possession). Their favorite position - terminal shoot of the young trees. They were

singing away at a lively rate when observed - at mid-day - A mourning dove was seen in flight between Grizzly and Big C. - Lovizon, 22 species. Monday - July 6-14 7-8 A.M. This trip over the same route as followed on a number of previous trips was largely a review of bird songs previously heard. The weather was cool and foggy and the birds were not as much in evidence as usual. Among birds heard or seen or both, were the warbling vireo, wood-pewee, Santa Cruz song sparrow, western flycatcher, bush-tits, tulecent warbler, brown towhees, spurred towhee, russet-backed thrush. A pair of Calif. jays were seen in low brush feeding a young jay In the vicinity of the hog serum lab, we heard the note of the chip-

Singing sparrow for first time. In brush by roadside - heard at once the soft subdued jay-like call notes of the song sparrow, and the sputtering of a wren-tit. Saw wren-tit. Noted that tail was about length of body. Also heard, buzzing of Parkman wren, - clear note of flicker heard in distance.
