(114) Her "conversation" this time consisted mostly of: "Pit-yourki- pit-yourki". Sometimes it is: "Beevoor, beevoor, repeat-repeat." at others: "Wheeo-wheat" and "Whit-you-whit-you". Of course it is impossible to represent these sounds at all accurately. There are many other conversational sounds made that cannot even be other approximated in writing. I do not know of any native bird that has the variety of "small talk" of these thrashers. This talk is also sometimes mixed with imitations of the California Jay, the Flicker, the Robin and the Sparrow Hawk. By "talk" I do not mean either the undersong or the full song. It is very low and I usually hear it when they are playing about me or taking food from me. Some of it is undoubtedly intended for me and some for each other, when together. Their loud calls are different again and usually consist of the opening phrase or two of full song. The undersong is a miniature full song, sung with beak closed, but even it does not contain all of the variety and richness of full song. The latter, when heard, say ten feet away, contains an astonishing variety of sounds which are absolutely missing when from the song as heard at a moderate distance, say 100 feet. These give the nearby song an entirely and more embellished different character, much richer than the distant song, which is fragmentary in comparison. May 3rd. At 7:20 Brown-eyes was on the nest, Green-eyes in the north-east corner digging. This is evidently the preliminary "thinking" period at the nest. Green-eyes ate worms, but he is still shy and needs a lot of coxing. He did not take them from my hand so I tossed them to him 2 or 3 feet away. The difference of eye color is very pronounced. At 9:20 I was thinning out the peaches in the "orchard" when I heard a thrasher call in the vicinity of the nest. I assumed that Brown-eyes was off duty and that, if she knew where I was, such as meaning, whining, "Yurubbing", Trilling and warbling
