K. Selander, 1952 4 Campylorhynchus megalepterus nelsoni La Puerta, 7000 ft., 31 mi. SW Orizaba, Veracruz, Mexico. August 1 through the oaks, calling occasionally. At no time was a "shree" call uttered. Thinking back to my first encounter with this wren yesterday, it may be possible that a jay of some kind was in the flock of wrens and was responsible for the "shree" cries which I heard at the time I encountered the wrens. Until I can get some more information in this regard, I am inclined to accept this explanation. Both adult & juveniles were present in the flock I encountered at 3:00 P.M. The sudden appearance of the flock indicate that the birds are traveling about the country instead of remaining localized in a particular spot. The size of the flock indicates that several family groups band together to form such assemblages. Noted that these birds were moving about in the brush in addition to the oaks. Compared to C. jocurus the call of C. megalepterus is higher in pitch, less resonant, and much more nasal. The wrens themselves are much more active and strikingly like Steller jays in behavior when excited or aroused to curiosity. Wren apparently foraging among the epiphytes on the branches of the oaks.
