He does not put himself out in the least to get the food himself on these occasions: I am supposed to do all of the work except the actual swallowing. If he drops it, as he frequently does in an endeavor to get it properly oriented so that it will go down easily, I am the one that has to recover it, for he usually will make no effort whatever to pick it up. This behavior, of course, is not really "a relapse into a sort of second childhood", but a reaction based upon his repeated experience that it brings about a certain desired result. (Or something like that). But what is to be said about those times when he cries in this way when he does not want food? As one of many specific examples: Today I gave him a live mouse in the outer cage where he sat quietly on the platform of the "house". I went away after he had disposed of it, returning in about a half hour. He greeted me with this cry, but, when I offered him food, ignored it and stepped to my shoulder. (The platform is at about shoulder height). There he disposed himself for an indefinite stay, seeming to be happy in having me stroke his plumage while he looked off over the surrounding landscape. On this occasion the cry was, I suppose, one of recognition of a friend and, perhaps also an appeal for attention. Physical differences between A and T. As judged by eye alone, there is less difference in size be- tween these two birds than formerly. Visitors frequently pick Terry as the larger of the two, but they do not make allowance for the disposition at the moment of the feathers of the two birds, nor for that curious illusion that makes the more distant bird look the larger. There is now, I think, little difference between them, though Archie is the larger. There is one respect in which there is no doubt, and that is: his two middle rectrices are cer- tainly wider. Further, although having no bearing upon size, he has more black inside of his mouth. He is also stronger, as witnessed by his ability to kill a mouse with greater despatch and in jumping up to a certain perch, uses his wings less. (Rhody can kill a mouse quicker than Archie). How high can RRs jump? Defining a jump as limited to height accomplished by use of the legs only, both Archie and Terry are able to make a high-jump— that is, a standing high-jump of 3 feet 1 1/2 inches (94.5 cm.) with- out using the wings even as sustaining surface. This is the height of a certain perch above a certain rock in the cage. In accomplishing this jump they also cover 1 foot 6 inches horizontal- ly at the same time. This height is fixed and does not necessarily represent the maximum possible by either bird. Archie usually does not use his wings in making it, but Terry frequently gives one small flap. To equal this performance, a man, using height of man and bird as a basis, should be able to make a standing high-jump over an ordinary two story house with ease! January 7th. to 14th., incl. A rainy period during which the rainfall for the season passed normal, notwithstanding the large early season deficiency. All birds under observation present and accounted for, but not very active. January 15th. About 11 A.M. Rhody was heard to open the season with his spring song: Coo, coo, . . . etc.; this is the first one heard from him for several months, and doubtless indicates renewed interest
