Postures at window. Ignores mirror. R searches trees. Possible explanations. Looking for birds' nests. (Though I have never seen him attack one). Looking for food. (Though I have never seen him get anything in a tree). Looking for a new nesting place. (This is quite possible) Looking for a new night roost. (Especially plausible if sought near the cage). A confusion of complexes or reflexes due to the season and the time of day, embodying nesting and roosting impulses both. Tries new location. At 5:20 he started in the direction of his nest with a twig, very late for him. He dropped it and went up a tree about half way there, and went to a place that looked good either for a nest or a roost. He began moving small twigs out of his way and tried settling there. He occasionally made ed softly. This is new on such an occasion. (For my benefit?). He came down and started to follow his usual route to his regular roosting place. I followed him. He is madly deliberate and composed when doing this. When he reached the street, instead of crossing to the Scamells', he kept on down the sidewalk going west, 6 or 8 feet at a time., climbed the bank to the lot west of here, entered the brush, then came out again to stand 6 feet from me, looking and listening for 5 minutes, stock still. He then went into the brush again, so I went around the street corner and stood on the sidewalk below the tree in which he formerly had one of his three known roosting places. In a few minutes he was seen approaching the tree. At 5:42 exactly, he began to ascend the main trunk, and at 5:50, he was in his old roost for the first time seen there in months. I hope for the night; but as I was getting chilly (Temp. 51) I left (Sunset 6:28--an overcast, chilly day). A and T not working. The young roadrunners showed no nesting reactions all day. Brownie comes into this room. Brownie continued to stick close to me when he needed food for his brood. At luncheon time he came into this room for worms four times. He has a bad time getting traction on the tile floor. Once when he left he struck a closed window and smeared "worm-juice"on it. Evidently it is not safe to let him come in without taking special precautions for his protection. I might have lost him. March29th. I look for R but he finds me. Rain during the night, clearing at about 9:50 A.M. (Now). At about 9 A.M., I went to Rhody's various roosts to ascertain if he might be weather-bound, without seeing him; but as I returned along the street, he came sailing down out of my place and trotted to me without invitation, placed himself in readiness to catch catch on the fly the worms he knew would be forth-coming. R cries. On way to roost. Changes roost. In bed at 5:50
