R.K.Selander, 1952 6 Compylhynchus brunneicapillus Sept. 4 16 mi. SE Lagos de Moreno, 6700ft., Jalisco, Mexico. from that of birds near Jiquilpan in August. I did not hear the loud "cha" call. Only sounds made were a series of low "caw" notes given thusly: "caw-caw-caw-caw-caw-caw" an old sound ing ->increasing pitch and speed-> series of notes) sounding for away even when bird is rather close. Watched adult ? give this several times from top of tene cactus. Tail held level when this call is given. Birds did not come well to my squeaks and imitation of their notes-although one juvenile did approach me while I was partially concealed. Adults apparently less interested. When the adult male saw me it flew about 30 feet away into another cactus and gave the caw call several times,-Young apparently are out of the nest now. Brown toucan in rather close association with the wren. There are many patches of vegetation suitable for these wrens along the highway from Jiquilpan to Laestecos. Probably much vegetation of this type has been replaced by corn and other crops, I am certain that rather extensive stands still occur on the mountains (foothills at least), so that there is probably fair connection of populations throughout much of the plateau region.
