Marsh Hawk, but I'm pretty sure it wasn't a Marsh Hawk since there was no white on the upper part of the tail. It may have been a Peregrine Falcon. Also a large raptor was seen on the west side of the Lagoon, way over on the other side, low over the sand dunes; it was too big for a red tail, didn't fly like a vulture and we assume it was probably a Golden Eagle. We'll check that out too--hope! Not many ducks down in the water, cormorants or anything like last year. There's some foam washed up on the shore. No phalaropes yet. See some small Ranunculus (?) that are still flowering down by the shore of the Lagoon. A wild strawberry? with a yellow flower on it. Saw a purple clover also flowering. A few scattered poppies that still have flowers. Gentle wind from SW; sky almost perfectly blue; warm. Marbled Godwit on the shore, flew east, tacking with the wind across to the other shore. A couple of ducks flew out which may be pintails, a white trailing edge on the wing, very drab looking; males are either in eclipse or they're not here. A couple grebes far out, unable to identify (Horned or eared) Also what looks like a California Gull. 11 avocets along the shore, probably con- servative, flew up and off. 3 Swallows buzzing over the water. Jim saw a Sparrow Hawk above a bluff about 50 yds. from the water. Several godwits on the other side. Horrible green sludge on this drainage pond from the farm adjacent to the Lagoon, unable to identify, smells bad, green-blue, thick. A board thrown on it won't go beneath the scum. A flock of 8 ducks flew out over the Lagoon, look like pintails but they're all the same color, very plain. About 10 "peep" on a side pond off the Lagoon, feeding around
