can view the surroundings and preen. Also men have numerous buttons, straps and pockets to be examined and worked upon and have the happy faculty of locating themselves as to sun, breeze or shade in a manner eminently satisfactory to road-runners. Their shoes, necks and hair are good to wipe bills on and they make fine landing and take-off eminences; besides this they turn over rocks and disclose many interesting crawling things, hand out water in glasses saving the trouble of going to the pool and serve a final snack to sleepy youngsters after they have gone to bed for the night. Altogether rather pleasant animals to have around, men. A and T 79 days old. Archie and Terry are now 79 days old, plus or minus 2 days. While Archie is still the larger bird, and it looks as if he would always be, the physical disparities between them in other respects have virtually disappeared. They are equally active and light in flight and have the same limitations and abilities. Deceptive appear- ance of size at distance. Curiously (like the thrashers) they look larger the farther they are away. An illusion, no doubt, for which the bird is not responsible. Nevertheless, whichever it may be, the nearer bird always seem to be smaller at the moment. Perhaps it is the same effect that makes the moon look larger on the horizon than it does when overhead, (although it actually is fractionally smaller in angular diameter on the horizon). Mammal-like actions and sounds. Again, curiously, these youngsters seem more like little animals, i.e.: mammals, than birds in their actions in an illusive sort of way hard to describe. Perhaps it is in their various utter- ances which, beside the rattle-boos and a soft dove-like hroo (which Terry now has also) consists in wanks, oohs, grunts like little pigs, mews like kittens, whines like puppies and a curious bleating ma-a-a like lambs. Besides these mammal-like sounds there are others such as quokh; a strange popping not made by the bill; a peculiar thin, harsh buzz of high frequency which is also sometimes punctuated by hollow, resonant pops of entirely different pitch, much lower
