swallows it. It is seldom that I can discover what it is. It is never an angle worm. Possibly it may sometimes be only a pebble. But there are times when it is seen to be a minute insect. From the fact that it is found beneath the surface a considerable distance it would seem that it must be the sense of hearing that enables the bird to detect its presence: yet, considering the distance of the bird from the object it hardly seems credible. The case of the Robin listening for worms in the lawn and getting them, at which so many people marvel, is really not ex- traordinary at all. Any person with normal hearing, under proper conditions, if told what to listen for and directed to the source of the sound, can easily hear angle worms working, as I have proved repeatedly to skeptics. On the fairway of a golf course after a heavy rain I have often heard a rushing sound coming from all directions as the worms discharged their waste at the surface of the earth --the "worm-casts" excreted by golfers on the putt- ing greens--and I have had a whole foursome (when there was nobody too close behind) stop, look and listen until convinced. Brownie and Nova have been much in the kangaroo thorn (Acacia armata) where nest 10 was started on Jan.31 last year, and where he and Greenie had one of their ill-fated experiences. February 1st. A rainy day. Rain began about noon yesterday. The bird world very quiet and not much in evidence. When Rhody appeared about 9 A.M., after a night of hard rain, he did not look very wet, and when he preened at my feet it was seen that he was perfectly dry underneath his thick thatch of feathers. He did not want the freshly killed mouse offered him. A live one he killed but abandoned. He refused meat also, but when I showed him meal-worms,, became interested at once, catching them expertly. All three road-runners will eat these creatures even, appar- ently, when not hungry. I kept away from the road-runner cage purposely until it was dark. A was in his regular place, but T was in an exposed position so I carried him to his shelf. This time it was too dark for me without a flash light. I tested T for eye shine with negative results. As these notes show, eye shine has been observed in these birds in the day time, but I have also seen it rarely under favorable conditions in human beings. In the generally accepted sense, I doubt if these birds can be considered as having eye shine. February 2nd. About 8:30 A.M. Brownie was singing loudly and continuously over at Robinsons'. I stood about 250 yards away and could see him silhouetted against the sky. (Sunny morning). Contrary to the usual order of events, Nova was singing her odd song in plain sight about 50 feet from me at the entrance to this place, in a climbing rose on the fence. It "ought" to be the reverse. I called B repeatedly and Nova moved to less than 20 feet from me-- another unusual happening-- and sat answering B from a perfectly
