They are now 16 days old, with a possible error of plus or minus 2 days. They would be easy victims for a predator in the field, although they can run fairly fast. but doubtless can not keep it up. The difference in size seems less. T is catching up. (?). June 17th. The young road-runners are much stronger. They can jump up, with the aid of their wings, to a window sill about a foot from the ground covering about 2 feet horizontally in the act. They occasionally essay sailing flights from my lap to the ground, and although they do not make very good landings. they are improv- ing rapidly. Both notice their reflections in the window and nibble at them. They are inveterate dusters. Both have discovered the "spread eagle" method of sunning them- selves. which Rhody, himself. has only been seen to use twice. Both also. and more frequently, use the split-down-the-back method. When disappointed in an effort to reach an eminence beyond their present capacities. they often express their disgust in a strik- ingly adult boo. They are ludicrously mature in their mannerisms and are almost perfect replicas on a small scale of their parents. Archie, especially. is just like his father. June 18th. B and family. Brownie. Nova and both of the youngsters of the last brood were together at the oval lawn this morning--the first time all have been seen together. Full song is being heard oftener and later in the day now. Archie collects gravel. Archie began this morning to select small gravel stones carefully and swallow them. It was clear that he used discrimina- tion. (Grind stones for his gizzard?). 12:30 P.M. Archie is beginning to pick up things and carry them about. such as pine needles and leaves. Just now he found a crooked, rusty nail and tried to "kill" it by slapping it on the ground just as Rhody does with snakes. He brought it to my feet, dropped it, then "maed" to be taken up into my lap.
