Zonaidura macrona Mourning dove 3 Apr. 1956 Between Cafeteria + Res Art - Nest in Cedrus tree. On horizontal branch about 4 feet high. May not be completed yet. One on ground with something in mouth flew to nest, other flew away. Just a very rough platform of small twigs. 4 Apr. Fulton St. along ath. Field - See Journal p.s. 20, 2Apr. 1956. Found 1 egg, 1 part of egg under Cedrus tree. Whole egg had a large hole near one end, small hole near other end. Eggs are pure white, whole one measures 27.0 x 20.3 mm. 18 Apr. Between Cafeteria + Res Art. - I have pecked at this nest often in the past 2 weeks. There has always been a bird sitting on the nest. Construction of a building near the area and all the noise associated including putting posts near and in edge of tree, has not made them desert. I am confident they were incubating on 6 April. 20 Apr. This nest is a mere platform of twigs, appears about 4" in diameter. About 9 ft up on a horizontal limb (diam. it is is about 4" past a major fork), and nests on a large and a small (1/2" diam) branch. Bird incubating usually sits 8-11, only once seen leaded N E-SW. Wide Fac. Tennis Court - Bird with about 8" twig in mouth walked to where live oak overhangs fence of court. Returned w/o twig and sat there. Could see no sign of nest.
