I am not acquainted. 3:30. I made some imitation worms out of soft food, suet, corn-oil and a little flour and water all heated together in a water-bath. This gave a mixture that was fairly elastic when cold, making very respectable worms. I went to the glade and the thrashers immediate- ly ran out of the bushes to me. Brownie jumped up to my hand to inspect the two "worms" I offered, but would not touch them. I offered them to Greenie with the same result. When I put meal-worms with them they picked out the real worms. When I tossed them to the birds they would run for them and Greenie would pick them up, but neither would eat them, although the Nuttall sparrows did. The two thrashers have been very lively and playful today, chasing each other through the bushes, dashing at one another sometimes from distances as great as 20 or 30 feet and playing hide and seek like young birds. Greenie several times tried Brownie's tactics, rushing up to her when she had a good prospect hole, seemingly in the hope that she would retreat and let him have it; but she usually ignored him completely and his rush ended tamely. 4:30. The birds are still unusually lively in all their actions. Greenie picked up a thick, heavy twig and dropped it in front of Brownie as if he were inviting a chase as dogs sometimes do. Brownie did not respond, being engaged in a new prospect hole, but shortly they gyrated around an old-man sage evidently in play. Brownie about 5 o'clock discovered an Argentine ant hole and dug rapidly, eating the pupae (and presumably also the ants carrying them). The ants crawled up her legs and she picked them off. Some I could see disappearing amongst the feathers and I expected some pyrotechnics, but she seemed to ignore them for the most part, although she did occasionally come out of the hole she had dug, pick off a few ants and return again, much as a man who is tending a smoky bon-fire comes out for fresh air. She did not finish the job,
