Robins (35) Pied-billed Grebe (7) Swainson Hawk (1) Killdeer (300) Amer. Merganser M & F Sora Rail (1) every field had some. Pintails (10) Coot (18) Treganza Herons (6) American Golden-eyes (275-300) There were in singles, pairs and large flocks. Observed one female jump directly into the air when frightened suddenly. They are a very wary bird, and are hard to get near. W. Crows (300) some feeding on the ground, others chasing hawks. Double-crested Cormorants - had white wing patches - They were flying upstream. Baldpates (1500) - about equal male and female. They were in pairs and small and large bunches all over the river and along the edges under brush on the gravel bars. American Raven several were seen along the high cliffs on the river. They appeared to have a nest in a crevice in a sandstone cliff (8). Common Canada Geese (40) - floating down the river and on bars, etc. They all seemed to be traveling in pairs. In one instance a 3rd party tried to join a couple and it was driven off right away. Ring-billed Gulls (4) White-crowned Sparrow (80) Lesser Scaups (14) - several of them were observed dead along the banks of the river. American Pipits (12) on the muddy strips off the river bank. Red Ant Hills Mourning Cloaks (20) Cabbage butterflies (2), cuckoo wasp (1) Jack Rabbit (1) Desert ? Cottontail (1) - quite reddish on back and sides. * Three of these came soaring in, overhead, that I could not tell. They seemed to be almost white under wings and body, with black wing tips. No banding or barring of the tail. Top side appeared grayish. About 24-30" wingspread. One was observed to dive repeatedly and intensely at smaller birds, redwings, etc., in the brush on a river island. They could be White-tailed Kites, although I wonder! No! April 6, 1944 - Mtn. Home Idaho 2-3p.m. Brewer Blkbrd Nevada Redwings Water Boatmen, Backswimmers, Whirlagig Beetles W. Meadowlark Mtn. Song Sparrow Dytiscidae, Water Striders (body 1 1/2" long, Pale Goldfinch W. Robin and reddish. May Flies. House Finch Tree Frogs - maybe not Hyla regilla. Seemed larger than those in W. Oregon. Heavily banded legs, salmon-red below. Dark and light brown body. Skin warty. Have discs on toes. Heavy dark line through nose and eye to shoulder V - patch or remnants of it on top of head. One that we captured had throat sack fully inflated and when we put him back in the water he swam crazily, turned sommersaults, dove, and squirmed in the water and came to the surface belly up, and motionless. After perhaps 30 seconds he "came to life", righted himself, and swam away. April 7, 1944 - Mtn. Home Reservoir - Dixis - 11 a.m. to 4 p.m. Scattered cumulus clouds strong winds at higher elevations. At the Reservoir: W. Robins Coots Cottontail Rabbit W. Crows W. Meadowlarks Pintails Nevada Redwings Amer. Ravens Wood Ducks Killdeer Eng. Sparrows Lesser Scaups House Finches Mallards Baldpates Bufflehead M & F, the male was brilliantly white and the female was quite drab, with a white spot on the side of the head. The male would dive and when he broke the surface the female would dive and when she came up they would both stay up a few moments and then they would repeat the above procedure.
