Mayhew 1950 Avocet 2. May 7 Conaway Ranch, 2 mi. east of Woodland, Yolo Co., Calif. toward the nest, a bird that had been feeding about 75 feet north of the nest flew over the area twice, giving a rather plaintive call as it flew. I assumed this bird to be the other of the pair, as it then alighted in the water close to the bird that had been sitting on the nest. May 13 (2) Another nest was found about 150 yards south of the nest found May 7th. Both of these nests are about 1/2 mile south of the first main canal crossing south of headquarters. The nest found today also had 4 eggs in it. The bird that was incubating at the time I saw the nest walked away from the nest about 50 feet toward a patch of water. Then it flew to some tules where the other bird of the pair was located. One of the birds gave the broken wing act for about a minute, then they both flew east of me a ways. As soon as I returned to the car, one of the pair flew back near the nest, and within 2 minutes after I reached the car, the bird was incubating. The time was 12:30 P.M. (3) Another nest with 4 eggs was found about 100 yards south of the preceding nest. All of these nests consist of a few dry weed stems placed at random in a shallow depression in the ground.
