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
