November, x9o2. [ THE CONDOR chanced upon a nest containing two eggs, uncovered; my visit to this nest on June 2o disclosed three eggs, well covered, evidently a complete set, No. 6. This nest was a large, strong mound, made as usual, 4 inches in height, 22 inches wide at water, cavity 7 inches across and x.5 inches deep. It was anchored in the edge of a small clump of reeds. The eggs varied from one in- fertile to an advanced stage of incuba- tion. At this time it appeared to me that I had located every nest of C. halbaelli in the swamp, but the morning of June t8 brought a pleasant surprise in the form of nest No. 7, a new nest, among buck- brush in the edge of the swamp. It was made on depressed branches of the bushes, a large, strong mass of decayed reeds with some new ?naterial inter- mingled in the top. Here were four eggs, well baked, incubation far ad- vanced; indeed, the shells appeared to contain only black feathers and bones. However, by patient applications of soda for the better part of a week, the only suitable article in camp, I made a fine set of this find. A review of the foregoing data shows that at least five pairs of U. holbo?lli were breeding in the region explored. I am certain that no other species of grebe was living in the swamp, and also that no more than the five pairs were inhabiting the region. No nest was found within at least one hundred yards of any other occupied nest. Seven sets of eggs were taken, as follows: June 4, five eggs, loosely covered, incubated to blood; June 7, four eggs, covered, incu- bated to blood; June x7, five eggs, un- covered, fresh, likely a second set; June i7, three eggs, covered, incubated to blood;June xS, four eggs, covered, in- cubation almost complete; June 2o, three eggs, well covered, incubated to blood; June 2o, four eggs, uncovered, fresh, evidently a second set. In the majority of instances, eggs were de- posited not oftener than on alternate mornings. Thus far I have no time to give to accurate measurements of the eggs, but in preparing them for specimens there was found to be wide variation in size, as they range approximately between 2.xo and 2.50 inches in length, and x.? 5 and t.5o inches in width. The Redwood Belt of Northwestern California. ii. LAND BIRDS. ?: BY WALTER K. raSHER. HE following list of land birds of the Redwood belt of Humboldt and Del Norte counties is by no means complete. The region is one of considerable interest, and in publishing the list I have been largely actuated by a desire to aid those Californians who are interested in geographical distribution. So far as I am aware no list of the breeding birds of this re?ion has yet appeared. With the exception of ,4rapelis cedrorum and probably of A/[elospiza cinerea phcea all the birds are breeding species-in the region. The time, circumstances, and limits of these notes have already been alluded to*. I am much indebted to Dr. T. S. Pal- mer for the use of a manuscript list of the birds of this region, made by him dur- ing the latter half of May and the first part of June, ?889. In each case I have accredited his records by initials. I am also indebted to Dr. C. Hart Merriam for the use of specimens in the Biological Survey collection, and to Mr. Robert Ridg- way for the use of types.
