Sept., 1912 DISCOVERY OF NEST AND EGGS OF CALIFORNIA PINE GROSBEAK 185 nest in construction, having a flimsy platform of small dead hemlock twigs from three to eight inches long, intermixed with a few stems of some tough wire-like shrub. On this platform rested the nest proper, of fine light-colored grasses. The whole structure is in no way fastened to the branch but simply rests on several twigs. Altho the nest can be easily seen through, in the tree it was en- tirely hidden, from above by the thick green foliage which hung over it only two inches away, and from below in like manner. The main branch on which the nest rests is well covered with the bright yellow moss peculiar to most trees in these altitudes. The nest measures eight inches over all, and the grassy interior is 3?x3?xlM inches deep. The second set of e,?,?s is similar to the type set except that they rather ap- proach elongate-ovate in shape. the ground color is slightly paler and duller, and the marking:? lighter and less scattered, except on one specimen whele they are Fig. 78. EGGS OF THE CALIFORNIA PINE GROSBEAK; UPPER ROW TYPE SET, LOWER ROW SECOND SET; EXACTLY NATURAL SIZE finely distributed over the entire surface. In the position shown (fig. 78) they measure in inches 1.02x.68, 1.00x.68, and 1.06x.68. It may be of some interest to compare the rarity and difficulty of securing the type set of eggs of the Gray-crowned Leucosticle, or Rosy Finch, with that of the California Pine Grosbeak. The former, although inhabiting a region more difficult to reach, can usually be relied upon being found in ?ertain localities. The Pine Grosbeak on the other hand is extremely erratic in its distribution. The habitat of the Rosy Finch along the timberless $ierran Crest is open while that of its neighbor just below is in the dense forests of a great woodland. While we saw several Rosy Finches engaged in nest building in our search of 1910 we were only able to definitely locate and reach but a single nest. On the other hand both nests of the Pine Grosbeak, while difficult to locate, were easily acces-
