frequent trips back and forth by the parent with one seed at a time. Finally they disappeared into the bushes. Lawn digging by thrashers Shortly after this the tract to the north of this place underwent the same operation as the one to the south, so that noise and confusion continued for many months longer. Also I was too busy myself to observe the birds much. As soon as I got a small lawn well along I began to notice small conical holes in it an inch or two deep with the largest diameter about the same. At first this was thought to be the work of flickers who had occasionally worked on this lawn, but one morning a thrasher was seen making vertical strokes with its bill followed by powerful side-sweeping movements to each side, throwing earth and roots several feet away. In later years it was noted that these depre- dations began about the time when the surrounding country was getting pretty well dried up and that they were confined to moist places and lawns. Eats cut-worms Until the autumn of 1931, as indicated by a few casual notes made at the time, thrashers were only occasionally seen in my garden, although it must be said that I was not really looking for them. They then damaged very badly a small moss lawn on which I had bestowed considerable care, in pursuit of cutworms, as I discovered by placing electrodes in the moss-patch and driving the worms out. However, I did nothing about it as the attacks were not renewed. More digging In July 1932 a thrasher began to appear quite frequently in the shrubbery, and occasionally doing a little digging in the lawn. Some time in September digging was started in earnest and one morning I found more than 90 fresh holes in a small oval lawn about 15 feet by 25 feet. Earth and roots had been scattered all over. Oval lawn Focus of garden This lawn is surrounded for about two thirds of its periphery by trees and shrubbery, with a driveway along the open side towards the house. It is virtually the focal point of the garden and a gathering place for birds, as a few feeding stations are maintained there, and it is well protected. The house is laid out on a level 8 or 10 feet higher with an open sided court or patio, also containing oaks and shrubbery and another small lawn, facing the oval lawn. There are also in this court various small pools, bathing and feeding places, and it is protected from all but southerly winds. It has both sunny and shady places at all times when the sun is shining and has become quite popular with the birds. At favorable times I have seen as many as 15 or 20 different kinds of birds in it in the space of a half hour. (July 4th. '1929, 12M. to 12:30 P.M., an unfavorable hour usually, 22 different kinds). Thrasher gets bolder I had occasionally thrown bits of bread to this thrasher and, after retreating into the bushes at first, he would sometimes come out, take the bread hurriedly and run off with it into the bushes. Finally he got bolder and bolder, at last coming out openly to dig in my grass plot in my presence. Decide to bribe him I decided at last to see if I could not bribe him to let the grass alone. So at the point where he most frequently came out of the shrubbery, I placed a little stand about six inches by ten inches and about 18 inches high from the ground. This had around it a raised
