194 THE CONDOR Vol. XIV muffled to the ears to keep out the biting frost of zero weather, I have heard this little fello?v's beautiful ringing song above the roar of the icy waters. Certhia familiaris montana. A few seen in the pine and spruce belt, but nowise common. One taken on Rook's Creek, 7500 feet, November 3. Sitta carolinensis nelsoni. Seen occasionally through the Canadian and Hudsonfan zones, but not common. Sitta canadensis. Common wherever spruce and pine timber is found, usually in 'company with Pentheste, gainbell gainbell. Penthestes atricapillus septentrionalis. Comm,on along Wood River in the willow and aspen thickets, but never seen in the coniferous belt. Penthestes gambeli gambeli. This and the next species were the most common birds in an? part of the mountains, outnumbering all other species three to one. On October 31 I was on Boyle Mountain at about 8000 feet elevation, and I spent about an hour with a flock of this species that numbered.well over one hundred individuals. Regulus satrapa olivaceus. Comm?)n everywhere in suitable forests. It was a pleasing sight to see these little mites searching the trunk and inner. branches of the spruce trees that were laden to the breaking point with snow. They appeared all unmindful of the intense cold. Planesticus migratorius propinquus. A single individual seen along Spring Creek October 27. FRO M FIELD AND STUDY Breeding of the Ba?d-tailed Pigeon in Marin County,' California.--While never resident, the Band-tailed Pigeon (Columba f. fasciata) was formerly intermittently abund- ant in portions of Marin. County, California. Sometimes it appeared in flocks of a hundred or so in the fall or winter when food conditions seemed to attract them, and was usually quite numerou?s in the spring and summer. The birds would then be in evidence from April to July, and might be seen picking up stray kernels in the fields just planted with forage corn..Or, later, when elder berries were ripe they would come in small flocks and feed in the tops of the elder bushes. It seemed as if they must have bred here in those days, yet with all the deer hunting, range riding and deliberate searching for nests we never had any actual evidence of this, excepting once, when a bird was seen carrying material for a nest into a fir foreit, though ihe nest was not discovered. This.pigeon is becoming scarcer all the time, and, while an occasional small flock is seen in this neighborhood, it never appears in such numbers as it did thirty, or even twenty years ago, and hence jt seems singular that the first breeding record for this locality should have been made only this summer, when but few are left in evidence. This record was made purely by accident, the bird having been flushed from its nest when the writer was survey- ing a line through a forest of second-growth timber on a steep hillside at Lagunitas, near San Geronimo, Marin County, on July 30, 1912. The nest, of small twigs loosely laid together and closely resembling that of a Mourning Dove, though naturally a little larger, was on an overhanging branch of a California lilac (Ceanoth?s thyrsiflorus) extending over a steep rocky place that was rather more open than the immediate neighborhood. The nest was about eight feet from the ground. The single egg it contained Was in an ad?/anced state of incubation, the embryo being probably within three days of. breaking the shell. At times the Band-tailed Pigeon, possibly on account of unfavorable food conditions in its natural haunts, gathers in large flocks in certain localities, and it then falls an easy victim to the hunter. Possibly also there are localities where it breeds in numbers and may easily be shot. Be this as it may, this fine bird is certainly and surely being de- stroyed faster than it breeds, and it is high time that it should be given some sort of pro- tection, and listed with game birds.--Josmm M^mur^m).
