(109) young bird that disappeared, although this is the first sign of ants which I have seen in the nest. They may also have caused the nest to be abandoned by attacking the pipped egg. (Who knows but that the attack by Brown-eyes on the ant nest record- ed in these notes--the only one witnessed--may not have been inspired by the attack of the ants on the nest?) I shall put a band of "Tree Tanglefoot" around the trunk of this tree where nest is, 3 ft, and also around the trunks of any other trees having branches interlacing with those of this tree. The birds worked very leisurely during the afternoon. Brown-eye has shown more anxiety as to the whereabouts of her mate during the last day or two, than usual. Several times she has stood near me and peered in all directions, evidently looking for him, at the same time calling. April 30th. At 6:30 neither bird was working at the nest. They were across the road at my berry-patch where they seem to find the digging very good. About ten o'clock They were both there and by offering them food I soon had them digging close to me. They dug mostly about the roots of the bushes. Brown- eyes unearthed a very large cut-worm and after breaking it up ate a portion, than ran over to Green-eyes and gave him the remainder. They kept up an almost continuous conversation with each other mostly low gurgles, short snatches of under-song and a low, guttural rasping sound, "blue-bird chirps" and, oc- casionally a drawn out "h-a-a-a-h" (like the word "hair", but without the "r"). Also a soft, high-pitched trill. I have not seen them visit the nest this morning. (Now 10:15) 4:55 I still have not seen them visit the nest today. They have been having a good vacation, poking around in corners where they do not usually go, examining cracks in the steps, going into the lath house (where I have never seen them before)
