As we walked through the water we found a nest of the Black Terns with two young, one downy and the other not yet dry from shell. No bits of shell in the nest. After we passed the bird returned promptly to the nest. Within a few minutes we found 6 Redwinged Black birds nests, three empty (or not quite laid), the others with 1, 2, and 3 eggs. Next a duck flew (Gagwall?) pretending to be wounded. Making the spot we went to it and found four ducklings about 3 in long, downy, which went swimming off while the mother tried to lure us away. One of the ducklings dove as Mr. Cauldwell tried to catch them. He caught one and we examined it, then let it go. Next came many Yellow-headed Blackbirds but we did not find their nests, the water being deep. Next a tree area; on the dry spots were many Killdeer but I did not find nests or young. A few Glossy Ibis flew in and we saw again the Foster Tern and a pair of Avocets. A colony of Blackbirds were very noisy. Mr. Cauldwell went into their tule patch and found the nests very close together. Many Barn Swallows were nesting under the bridge. One nest had four eggs - lined deep with feather
