to be on the mend. Anyway they are extremely active and are tremendous diggers and their droppings are normal. (Not green). Fresh leaf-mould and loam are put in the cage once or twice a day. They go over it in minute detail. Okii has developed a "digging song", like Brownie's in min- iature, although he sings his "regular" song less than formerly. Chiisai scarcely sings at all now, for some reason or other. His irritability toward Okii seems to hve disappeared. He is much more restless than Okii, especially at bedtime. Like Terry, when disturbed about finding a sleeping place, human contact seems to calm him. He demands much more attention than Okii, calls for food more than O and more than he did at first. Curious how indifferent both are to meal-worms; yet these creatures were the most potent, civilizing factor in my contacts with other thrashers at this place. I have regarded them as the Big Medicine for thrashers. But O and C, while they will eat them, more often than not reject them entirely when one is uncovered in digging and go on looking for something else. Young thrashers and gopher snake. On the way to the cage this afternoon I picked up a gopher- snake over (?) 3 feet long. As I approached the cage O and C (unexpectedly) rushed to the wire with spread wings and tail, clucking as Brownie did when he saw a snake, and tried to get at it. It is almost certain that they never saw a snake before; yet it seems to have been recognized as an enemy and not feared. (Or perhaps I should say: not avoided). June 22nd. to 26th., incl. (Notes written 26th.). During this period affairs progressed normally. O, C and snake. The snake was introduced into the cage with the young thrash- ers and held in control. Both young birds immediately manifested great interest, clucking and stalking around the snake stiff-leg- edly but not approaching nearer than about 2 feet. They did not offer to attack it. Rhody and snake. Rhody was given an opportunity to react toward the snake, which, on this occasion, needed no restraint as it remained quietly coiled, though in defensive attitude. Rhody walked around it about as the thrashers did, flirting his wings at it only once. He seemed to consider the affair as not his particularly, but one in which our interests were about on a par as spectators: thus he showed a tendency to stay close to me and look at the creature from my point of vantage. (Possibly he was studying my reactions!). Thrush brood. (Parent shades them). The thrush has succeeded in hatching all (?) the eggs in the nest. The incubation period appears to be 12 days. The last few days have been hot (Upwards of 90 deg.). At such times as a beam of sunlight penetrates through the canopy of the trees and strikes the nestlings one of the parents sits on the edge of the nest and spreads its wings to shade the brood, panting. Effect of heat on young thrashers. On these hot days the young thrashers apply to me less often for food and, in fact refuse it often. They remain in the shade for the most part with wings spread and bills open; yet, at times they will come out deliberately into an open, bare spot and take prolonged sun-baths, seeming to be on the verge of expiring. They use the standard side-to-the-sun
