1646 would be unable to resist the temptation of carrying it off despite the fact that it looked just like any other blackened and sodden fragment of shrubbery material with a gloss of algae on it here and there. As soon as he saw it he seized it and hurried toward the nest. Meanwhile I had put some more of this same plant at his "take- off" point and he did not fail to discover it, adding a portion of it to his burden and arranging it carefully inside the house. I nearly missed recording the most unusual feature of this series of events: As he approached the nest tree with his burden brought from the west lot, he began to bow and hroo--that is,he carried this tuft of nesting material with the display heretofore-- unless I have completely forgotten--used only with food such as mice and lizards. Mar. 18th. to 22nd., incl. During this period of continued rainy and cloudy weather with little sun I was pretty well occupied in transplanting azaleas and rhododendrons to less crowded situations, therefore did not keep close watch upon the birds. However, my work was mostly within 50 to 100 feet of the thrasher and road-runner nests, so it was possible to keep pretty well informed upon local events. Rhody on descending slope of his harmonic? Rhody worked little on his nest, being seen to carry material to it only once or twice a day, and it was all lining--mostly frag- mements of the composite and some bunches of pine-needles. He sat in the nest a great deal as though incubating--sometimes as long as an hour or thereabouts. He was not heard to sing, but accepted mice and salamanders, usually with appropriate ceremony. Some of the mice he carried about for as long as 3 or 4 hours, but others were eaten in less than a half hour. He also accepted centipedes (some of which are now carrying clusters of eggs) but did not display for anything so small. He continued his visits to the magpies and once was seen to spend an hour on the roof of the house across the street, where his vocalization was confined to rattle-boos entirely. Thrashers incubating faithfully. The thrashers, since deviations from standard routine were noted herein, settled down to conscientious appli- cation to the job of applying calories to the eggs and the few chang- es of shifts actually observed in progress were made without expos- ure of them for more than a few seconds. As a rule changes were made without the bird on the nest calling for relief; but there were ex- ceptions. There was little song anywhere near the nest and not much more elsewhere. Neo, when off duty, especially in the morning hours, could generally be counted upon to visit the extreme north-easterly boundaries of his presumed territory and there sing in competition with the bird supposed to be Inver in his area. Even Brokenwing, who has been the most persistent musician, during the past few months (within a radius of 300 or 400 yards) declined markedly in frequency and duration of song. Probably he has a nest also. White-throated sparrow still here. The white-throated sparrow continues to visit the feeding station just outside this window in company with the other Zonotrichias, with whom his relations seem to be perfectly matter of fact. As far as I know, there is only one of him here. Mar. 23rd. (Sunrise, if there had been one, 6:10, sunset 6:24). A rainy night and still raining (10:45 A.M.). "The climate
