Robins, a few; Varied thrushes, occasional, but not yet common; Flickers, several, Nuttall wood-pecker, occasional; Juncos, many; Cooper hawks, too often; Sharp-shinned hawks, occasional; Red-tailed hawks, occasional; Sparrow Hawks Linnets, several; Purple finches, several; Green-backed goldfinches, several; Willow gold finches, less often; Pine siskins, occasional flocks; Anna humming-birds, one or two, now doing power dive; Blue-birds, occasionally flying overhead; Audubon warbler, one ********************** 1939 ********************** January 1st (Sunrise 7:25; sunset 5:01). Fair weather continued throughout the day. Thrasher song first heard at 7:10 A.M. and thereafter occasionally throughout the day. Neo and N2 given worms several times. The spotted towhee now competes actively with them for his share, but Neo manages to get most of these intended for N2 and "Spots". Rhody has not sung yet. Rhody did not wait to be called for his mouse, but went to the cage for meat instead. He slept in No.1 and was "handed" a small mouse there at 5 P.M. Unless he sings by the third or fourth (?) of this month he will be off schedule. Humming-bird patient. Beginning yesterday the hummer has shown that he can hover at a flower and has several times repeated, though somewhat laboriously. It happened first when a spray of kuphea (sp.?) (Cuphea) prevented access to his food bottle from the perch, so he was forced to hover in the air to get at the contents. Blue phase of Anna hummer's gorget. This blue phase is observed every time the hummer bathes, provided he wets his gorget thoroughly. When it is saturated it is black as seen from all angles, but at a certain stage of dryness, the blue appears, gradually contracts in area and is replaced by the normal color completely in 15 minutes or so. It is necessary that there be a film of moisture on the feathers, as far as present experience goes. The blue is a brilliant metallic. I am not sure yet whether, in the blue state, any other color but black (calling black a color) can be seen when viewing the blue area at various angles. Hawk Raid. A hawk killed a junco outside this window, 15 feet from me while January 2nd Fair morning, increasing cloudiness toward noon.(58°). Thrashers present, with early song. Neo and mate came for worms about 10 A.M.
