July, 1912 A JOURNEY TO STAR LAKE COUNTRY AND TAHOEiREGION 147 A nest presumably of the Pintail Duck (Dafila acuta), which I had pre- viously found, was also revisited as I desired to show it to Mr. Carriger. On reaching the nest, however, we found it deserted and the six eggs emptied of their contents, scattered about on the grass. Mr. Carriger located his first nest of the Ruby-crowned Kinglet today in a lodge-pole pine. Examination showed it to hold seven fresh eggs. Nearby one of the Yellow Warbler was noted placed in the dead portion of a willow without any attempt at concealment and yet for this very reason more liable perhaps to be overlooked, as nests of the Western Robin and Western Wood Pewee often are, which are built in dead or burnt trees. Three nests of the White-crowned Sparrow, all on the ground in meadow' land, were noted on June 7, one with four small young, one with one and one with four eggs, fresh. In a dead pine Carriger excavated a nest of the Pygmy Nuthatch (Sitta pygmaea pygmaea) with small young, while a nest each of the Williamson ( Sphyrapicus thyroideus) and Sierra Sapsucker ( 3'phyrapicus varius daggetti) in dead portions of live lodge-pole pines were found in a like condi- tion. We saw the first Gnatcatcher (Polioptila, sp.?) for the Lake Valley re- gion today and were much disappointed in being unable to secure it. As we intended leaving 'for the long tramp to Pyramid Peak the following morning we spent June 8 leisurely rowing along the lake shore east and south- east of Bijou. Many nests of the Tree Swallow (Iridoprocne bicolor) were noted in cavities in piles in deep water. Most nests contained either eggs or young varying from five to seven in number. The Tree Swallows were not the only species to take advantage of the protection afforded by water-bound nesting sites, for numerous nests of the Brewer Blackbird and one of the Mountain Bluebird were also noted. The most remarkable, however, were two of the Red-shafted Flicker, both with ahnost full-grown young, some of which in the excitement caused by our approach fluttered into the water. For a time Carriger and I were kept busy returning them to their protected and yet perilous dwelling place. The day's work closed early as we had to spend considerable time after reaching camp preparing for the long trip to Pyramid Peak, already recounted in a previous number of T?tE CONDOR. THE PRESENT STATUS OF THE COLORADO CHECK-LIST OF BIRDS By WELLS W. COOKE HE appearance of "A History of the Birds of Colorado," by W. L. Sclater, reviewed in this number of TttE CON?OR, marks an opportune time for presenting the status of the Colorado state list of birds in the light of the new records furnished by Sclater and accessions that have become known since the third supplement to the Birds of Colorado was published in the Auk for October, 1909. The Sclater list of 1912 shows both additions and subtractions as compared with the Cooke list of 1909, as shown in the following table.
