We are still decidedly behind Texas, with its 605 species and subspecies (see Oberholser, Con- dor, xix, 1917, p. 68); but we are steadily catching up!--J.

A Northern Record of Mimus polyglottos leucopterus.--On the 28th of July, 1918, while returning by auto from a reconnaissance trip in Humboldt County, Nevada, we en- countered two Western Mockingbirds on Duck Flat, at a point some miles northwest of Sunkist (formerly Duck Lake), Nevada. The occurrence was so unusual that I stopped the car and made sure of the birds' identity. The birds were straggling at some distance apart and appeared to be working their way slowly northward, fluttering from clump to clump over a luxuriant growth of sage. The record station is well above the forty-first parallel of latitude, and not more than six miles east of the California boundary line.-- W?.?.IXM LEo?

Sapsuckers and Hummingbirds.--In early June of this year (1918) I was collecting in the Moose Mountain District (southeast corner' of Saskatchewan). This is a hilly dis- trict, thickly wooded, with numerous lakes and sloughs, surrounded by flat prairie--an "oasis in the desert". Near Fish Lake, each side of the trail, were a few birch trees among the poplars. I noticed that Yellow-bellied Sapsuckers (Sphyrapicus varius) had been at work on one of the birch-trees; some five or six rows of holes were m?de abou( ?welve feet from the ground. As I looked at this tree, a Ruby-throated Hummingbird (Archilochus colubris) came to it, hovering in front of, and probing, the holes, feeding on the sap. I had never seen colubris thus feeding, and stayed at the spot a couple of hours to make observations. Shortly a male Sapsucker came to the spot, drove away the hummingbird and commenced to feed, followed by the female who drove away her mate. Sitting partly hidden by the underbrush close to this tree, I noted that a hummingbird came, on an average, every ten minutes, a sapsucker every half hour. As I needed specimens o[ this usually scarce species, as well as desiring to know if it was the same two or three birds which were being attracted to this feeding place, I took (with .22 shot cartridges) six hummingbirds, four males and two females; but still others came to feed as before. This was between 8 and 10 A. ?. Passing the spot on my way back about 5 r. ?., I saw another, but had no time for further observations. Examination of the birds taken showed no signs of minute insects, but considerable clear liquid came from the mouth, which satisfied me the hummingbirds were actually ?eeding on the sap.--H. H.

Western Golden-crowned Kinglet In Los Angeles.--On November 27 of this year (?918), I picked up in my yard in the city of Los Angeles an adult male Western Golden- crowned Kinglet (Regulus satrapa olivaceus). From time to time during the past five weeks, the notes of this species have been heard in the locality, but no view of the birds was obtained until the above date when three times during the mc?ning a small flock of them visited the premises, feeding in oak and sycamore trees. The elevation here is 500 feet above sea-level and constitutes the lowest point at which I have ever observed the' species so far south as Los Angeles.--LOYE M?L?.r?, State ?ormal School, Los Angeles, December 10, 1918.
