dropped down from my knee and searched it thoroughly for the worms which were not there. B's versatility in song. Brownie came to me for worms by the lemon tree at the oval lawn, then retired to the ground about 8 or 10 feet away and sang quarter song continuously for about an hour, stopping only when pigeons approaching on the ground, caused him to move elsewhere. During this hour (estimated) there were no pauses in the song for more than 4 seconds (by the "one hippopotamus"method ) barring one of about 10. Even pauses of 4 seconds duration were rare. With the exception of a few phrases that I have recorded and three or four different kinds of imitations, it was all made up of "words", and indescribable sounds, constantly changed and apparently drawn from an inexhaustible vocabulary and repertoire. Granted that one is unable to grasp and later recognise, when again heard, syllables and sounds from a rapidly uttered and complicated performance like this, still it is my belief that Brownie has, in "music and words" actually thousands of phrases. (In "words"alone, or rather complete phrases of syllables--not counting individual syllables--I wrote down long ago somewhere in the neighborhood of a hundred different examples, and I am satisfied that the number thus recorded is but a fraction of those actually heard but impossible to put in written form). J.M. At 6:45 I went to the tree into which Rhody retired last evening. He was there, in the same spot. Evidently this is it . September 19th. Thrasher song. Thrasher song was heard at 5:30 A.M. and was fairly continu- os until about 9; Brownie was assisted by several other thrashers off to the north, west and south. Road-runner eyelashes Lashes on lower lids also. By scrutinizing A and T at "reading distance" (9:30 A.M.) it was seen that, as suspected, they have lashes on the lower lids as well. These are very fine and short and, from present observation seem to begin at the forward corner of the eye and end about half-way back. (A magnifier might show greater extension). Lashes are moulted. Particolored lashes. It was noted that Archie has lost several of his upper lashes on both eyes; the follicles from which they grew can be plain- ly seen without optical aid. Presumably eyelashes participate in the general moult and at the same time. T, as usual, is behind A. On both A and T the three or four lashes on the upper lid located near the anterior corner of the eye are not entirely black. They are "white" from the base for perhaps half of their length and then black. (I wonder what function this serves). Rr"mouths " Rhody As far as can be seen Rhody is all "black"(probably a deep purple) inside his mouth--tongue and all--as far back as the gape, (?) and perhaps further. Archie Archie, who can be observed to better advantage, is the same, except as to a line (median line)"on the inside of the upper mandible beginning at the tip and broadening as it extends to the rear, which is colored more or less like the lightest portions of his bill, and which seems to like it in texture. (As recorded, both youngsters were originally pink, and the change of color, when first seen in + a culture?)
