 32 THE CONDOR Vol. XVI RED-SHAFTED FLICKER. Colapres cafer. collaris. Common resident. While most numerous in winter, several cases of nestin'g have been reported. nite often individnals are'seen about the lower Campus, sometimes perching on build- ings. ANNA HUMMINGBIRD. Calypte anna. Common resident, likely to be seen on any part of the Campus. Of regular presence around the botanical garden and along the plantings of red geraniums and tobacco elsewhere. Nests have been found situated in live-oak trees on the lower Campus. ALLEN HUMMINGBIRD. Selasphorus allertl. Common sammet visitant. Ar- rives very early; first dates: February 25, 19o4, February 13, I9o6, March 14, I9II, and February 24, I9I 3 (A. S. A.). The grove around the Greek Theatre is a favorite resort for both species of hummingbird. Nests have been found there, as also along the tipper Strawberry Creek. March I5, i93, a nest and two eggs was found within ten feet of this stream, located in a shrub two feet above the ground (H. ,C. B.). The adult males are most likely to be found high on the hillsides, at the upper edges of the tracts of chaparral. SAY PHOEBE. Sayornis sayus. Observed but rarely on the ampus and only aq an early winter visitant. September 9 and 2I, 93, one stayed ;*round the foot-ball bleachers (J. G.). October I6, I9II, tt early dusk, one was observed fly-catching on the roof of the Fertilizer Control building (J. G.). November I6, I912, one was seen in an orchard on the hillside above Mosswood Road s. A.). BLACK PI-IoE. Sayornis nigricans. Residen in small numb.rs. Occurs singly or in pairs along the ravines (when these contain running streams), around the milk ranch up Strawberry Creek canyon, and occasionally on lawns and in gardens, especially where there are fountains. One bird in I9t 3 had a regular forage-beat between the Greek Theatre and Bacox: Hall. OLIVE-SIDED FLYCATCHER. l111tt81101S borealis. A snmlTler isitanr, having been seen during the months of May to August, inclusive. Earliest observed ar- rival, May i, i9i 3 (J. G.). During May and Jmte the far-reaching, three-s. yl- labled cry of this bird can be heard' from almost every point on the Campus. But the birds themselves adhere closely to stations along the bases of the hills, usually in the pine and eucalyptus groves. The call is generally given by the bird as it perches at the summit of a eucalyptus, or upon the bentsover tip-top of a cypress. The grove immediately around the Greek Theatre has been the ,regular rendez- vous of a pair during each of the preceding five summers. Allother pair is locat- ed near the Institution for the Deaf and Blind; another has been sen near the ,.Center Street entrance. No nests have been seen, but there is no doubt that broods are reared regularly in the vicinity. This is an occurrence of more than local interest; for the Olive-sided Fly- catcher is a typically boreal bird, and, moreover, one that affects evergreen for- ests as a rule. Yosemite Valley, for instance, exhibits the type of habitat pre- ferred by this species. Its appearance here within the past few yearg seems to be correlated with the growth of the planted groves, together with the presence of a cool summer climate. WESTERN WOOD PEwEE. ]gyiochanes richardsoni richardsoni. Summer visi- tant, observed in varying numbers from year to year during the months frorn May to August, inclusive. Earliest recorded arrival, April 2, I9 3 (A. S. A.). Nesting sites are selected along the alder-lined ravines, as well as among eucalyp- tus groves wherever these occur. One occupied nest was observed July 24, 9o9 (J. G.). It was located 25 feet from the ground on a bare lorizontal ucalyptus
