eggs, and one with four eggs in which incubation had begun. The nests were made of .?ieces of weeds rather carelessly built up on the mud. Some were found where the water was a few inches deep and some where the mud was drying. The one with broken ?ggs was on a clump of "red-weed" where ?he receding water had permitted complete drying. The broken eggs apparently had been eaten by some mammal or bird. The sets of one and two eggs collected by Dr. Evermann are now in the collec- tion ot the California Academy of Sciences. The set of four is in my collection.--J. A.N DENBURGH, San Francisco, December 6, 1918. Nighthawk Observed in San Francisco,--On the evening of September 18, 1918, I happened to be standing at my bedroom window, on the upper floor of the house, absent- mindedly looking at the sky, when what appeared for the moment to be a 'far distan? but exceedingly erratic sea-gull came above the horizon and at once attracted my atten- ion. Numerous gulls had been flying over without especial notice, but this individual seemed to have gone crazy as it flew into the west, or else was forgetting how to fly. Just when it nearly disappeared from view it suddenly turned and flew back almost di- rectly overhead, disclosing the 'fact that instead of being a gull it was a nighthawk. The white wing bars were visible, yet it was not possible to locate their position accurately enough to state the species, but it was presumably a Pacific Nighthawk (Chordeiles minor hesperis). On looking at my watch it was exactly 7:20 P.M. The incident was noted down as a matter of interest and as a record of date. Three nights after this, that is, on September 21, I happened to be at the same window at the same moment, and across the sky flew the same, or another, nighthawk, again proceeding westward. This time it did not turn, but disappeared in the western sky. I went out inte the street to have a wider view, but saw nothing further. Im- pressed by this repetition the next evening saw me early in the street, and on the look- out for more developments. At precisely 7:21 a nighthawk appeared in the east and pursued the same course as before, again disappearing toward the ocean. Each time the bird's course was about over and parallel with Pacific Avenue or Broadway. The next few evenings were foggy or lowering and the bird was not' seen again.--JosrPH MA?LL?,?RD, San Francisco, October 1, 1918. Notes on Red-headed Woodpecker and Jack Snipe in New Mexico.--In a recent issue of THr Co?Do]? were published notes made by several New Mexico ornithologists on the occurrence of the Red-headed Woodpecker (Me?aner?es erythroce?ha?us) in this state. It was pointed out that all the birds so far observed had been on or near trans- continental railway lines, indicating that the movement across treeless plains had fol- lowed the lines of telegraph poles. It might be of interest to add that-on August 18, 1918, at a point about four miles north of Albuquerque, and within a quarter of a mile o the main line of ?t?he Santa Fe Railway, I observed an additional adult. Red-head. I approached within twenty ?feet of the bird so that there can be no question whatever of identification. On the same day I also observed four Jack Snipe (Gallinago delicata) in the same localiy. These birds were so tame and unsuspecting that I was led to believe that they had been raised in the locality. I do not know whether Jack Snipe have been known to breed at this altitude (5000 feet) in New Mexico, but this record indicates that they may be found here during the breeding season.---AL?o L?oPOL?), X?buquerque, New Mexico, ?ugust 21, 1918. Nesting of the Band-tailed Pigeon in' San Diego County, Callfornia.--I have recent- ly received an egg of the Band-tailed Pigeon (Columba ?asciata) taken on Palomar Moun- tain, San Diego County, on October 11, 1918. This was perfectly fresh and was the only e?g in the nest, which was situated in a post-oak near the side of a road and was twelve feet above the ground. The average of 13 eggs given by Bendir? is (as reduced from millimeters to inches) 1.57x1.13. His largest egg measured 1.72xl.20. This egg of rains measures 1.93xl.07. I have 'the report of another egg ?aken in the same locality on October 14, incu- ba?lon commenced. This, also, was in an oak about twelve feet above the ground.. The
