Article abstract: This paper is a continuation of our report on the life history of the Cactus Wren (Campylorhynchus brunneicapdlus) in the vicinity of Tucson, Arizona. In Part I (1957) we described the winter activities, roosting nests, song, territorial establishment, and pair formation. Part II (1959) followed with a discussion of the breeding nest, the defense of the territory, and the time of laying of the first egg. We have banded 18 additional Cactus Wrens in the Kleindale Road area since May 21, 1957, when Part I was completed. The total is now 89.
