June 15, 1944 - Area II, Mtn. Home 9 a.m. The female marsh hawk was about 600' away from the nest, very busily engaged by pursuing Brewer Blackbirds, as I approached the nest. She came in a hurry, when I reached the nest, and proceeded to Dive-bomb me vigorously ! It was a good thing I had a helmet liner on because she hit it 3 times while I was at the nest. There were only two young in the nest, the youngest and the third from youngest, the others being scattered under the surrounding weeds. I got a picture of the two on the nest, with the larger scolding and defying my presence. Here is a description of the largest young bird: Body was 10-11" long, and still predominantly covered with wooly down of a dirty gray color. Bill is yellow on top, has a black tip and sides. Feet are yellow and 4 1/2" long. Eyes are dark brown. The wing primaries are 5" long, and a dark gray-brown color. A few feathers and feather quills are present on the shoulder, and under the wing on the body. The head is 1 3/8" wide and about 2" long. By now, the nest has lost all shape and form, the area in a 3 foot radius of the nest now being well-trampled down, and open. The birds can be seen from 3 different directions, as far away as 50 feet. There was no sign of the male being in the vicinity. June 15, 1944 - Mtn. Home Reservoir - 10-12 a.m. Saw a raven fly up from a jack rabbit run over in the road, with the two ears and connecting skin of the jack rabbit carried in its bill. White-rumped Shrike. Adult had no barring on chest and no white or pale color on bill. The nest contained 6 young. Evidently the one egg, that hadn't hatched lasttime, was no good. Description of young: Head and bill 1 1/4" long, bill is hooked. Body 2" long, fully feathered with gray color and fine white bars. Wing primaries 1-1 3/4" long. Tail quills 5/2" long. White feathers sparse on belly. Ear opening partly covered. Foot 1 1/2 and grayish. Claws 1/8" long. The pair of adults stayed close, the brighter ones was very bold, and when I would put my hand near the young, it would approach within 4 or 5" of me. However, I couldn't seem to maneuver the sun, the bird, the camera and myself into a satisfactory setup for picture taking. Mallards (and young) Pintail Coots Wilson's Phalaropes, 2 pair of them. Black-billed Magpie nest F had the young to the size where they would be ready to leave the nest in a week or so. Lewis Woodpecker. Saw one near town, on the way back in. Redwings Green-wing Teal Cinnamon Teal male, Marsh Hawk Killdeer Crow June 17, 1944 - 830 a.m. to 430 p.m. Mtn. Home AAB to Snake R and return. A pair of nighthawks have a nest in the rocks and gravel just off the EW runway. 2 White-throated Swifts, very bold and flew close by us. Horned Larks Black-billed Magpie Rock or Canyon Wren Flicker Cliff Swallows Sparrow Hawk Lazuli Bunting Bullock Oriole June 18, 1944 - Area II, S of Mtn. Home 5 p.m. 4Cu. Went to see how the young hawks were getting along, and not a sign of them around the nest. I didn't see any adult hawks in the area, either. I searched the surrounding brush and grass for 100' around the nest. Evidently the adults have moved the young, because I know that at least 3 of them couldn't fly ! How far did they move them? How? Why? Nice questions to be answered. Unless I accidently run across them at a later date, this concludes the Marsh Hawk study began April 17, 1944, just two months ago ! June 20, 1944 - 430 CWT Tinker Field, Oklahoma, City, Oklahoma. I observed a Horned Lark in the grass just off the runway, to the left of the B-24 I was in. We were waiting to take off. As we swung the plane into the runway, this brought the horned lark into direct line with the full blast of the "prop-wash", bowling it over ! It recovered and sought shelter behind a large tussock of grass. It hugged the ground as closely as possible.
