 Sept,1912 DISCOVERY OF NEST AND EGGS OF CALIFORNIA PINE GROSBEAK 183 while occasionally approaching quite close never came within arm's .length as did the female. Sometimes the latter would hover directly over the nest melodi- ously twittering. Neither bird made any attempt to resent our intrusion as birds of a more combative temperament like the Brewer Blackbird or Olive-sided Flycatcher would have been apt to do; in fact, they were of a remarkably gentle and affectionate dis*position, and a number of times the pair were noticed billing which shows this habit is not necessarily confined to the time of courtship. The call-note of the Pine Grosbeak, and we surely had an unequaled oppor- tunity for hearing it, is a two-syllabled call bearing some slight resemblance to the words "all-right". Although Chester Barlow has stated that it is a "harsh call-note like that of the Louisiana Tanager", we cannot agree with him. In the first place, "churtig", the call of the Tanager is not itself particularly un- musical and in the second place the call note of the Pine Grosbeak is much more melodious being peculiarly clear and liquid. It is of an earnest, pleasing, reel- Fig. 76.

It will also he rememLered that Mr. Price, in his notes, states that "the call is not loud nor harsh like that of the Western Evening rosheak." As this was the identical place where we had seen two Pine Grosbeaks the evening we reached the Plateau we felt sure that these were the same pair of birds. At both nests observation showed that incubation was being done entirely by the fmale. In no hstance was the latter fed on the nest but in some nearby tree. At other times the bird was seen foraging h herself. the hird's food being always so readily available that it was unnecessary for her to remain off the nest but for a very short period. We had visited this same locality several days before but on that occasion as the male wa away and the female sittiug dose on an almost invisible nest, the Pine Groshea and her home escaped our notice. After the photographic work was over, the nest and eggs with the parent
