Sandhill Crane, gave light gutteral rasping all the time it was in flight. Osprey, notes on one I observed at from 1335 to 4115 this afternoon. It came up the river, about 50 feet above the water, hovered, and dove out of sight, into the water, before I realized what it was. As it came up, it seemed to have some- thin in its talons, which later proved erroneous. The bird had its right foot deformed, either clubby or otherwise. Just about the time it had shaken the water off its feathers, it met a female Marsh Hawk, heading downstream, as the osprey flew upstream. Both birds made some high screeching or squeeking notes at each other, and the osprey gave way, and the female marsh hawk continued on in its intended flight, passing almost directly over- head. The osprey circled directly over me several times, but I didn't seem to bother him in the least! He circled around, and then hovered over a particular eddy, at the edge of the river. It hovered in such a position that its line of sight was 90° or directly crossing the rays of the sun to its right, and also so that it was "down-sun" from the objective in the water, thus not casting any shadow on the water. By this method of sighting and searching with those telescope-powered eyes, it eliminated reflection of the sunlight from the water: . Quite a strong wind was blowing. All dives were made upwind, or quartered into it. Dives were made at about a 60° slope from the water surface, and were usually started at a height of from 40 to 60 feet. Wings were only partially folded at the start of the dive, but becoming more folded as the dive progressed. They were closed, or folded tightly, just prior to the birds contact with the water. Its entire body went below the surface for about 10 seconds. Then, using its wings to pull its body to the surface, and out of the water, it would fly just above the water, up-wind, shaking its body, tail, and wing feathers vigorously. After two un-successful dives, probably caused by having only one good talon, it flew to the other side of the riverand landed in 4-6 inches of water. It did nothing but sit there, in the water, for about two minutes, and then it started to bathe, using exactly the same motions that I have seen a Robin use, in our bird biath, at home. This bath lasted for at least 7 minutes by my watch, and it was very busy the whole time. When it had finished, it just stayed in the water and looked around. A green-wing Teal flew by, circled, and landed within 5 feet of the osprey. A magpie came down and landed on the gravel beach, just 2 or 3 feet from it. Evidently both of them thought it was a duck, or else were very curious! Oh yes, later on, I also saw it miss two other dives into that same eddy. Also saw flickers pheasants, and a Farallon Cormorant, that was flying down-river, but not over the water. It was brownish-black and had a yellowish throat pouch.
