R.K.Selander, 1952 2 Compsylophus megalopterus nelsoni La Puerta, 2000 ft., 3 mi. SW Onzala, Veracruz, Mexico. present. Shot two more. The others moved on through the trees rather silently. This species is much more active than C. jocous: moves faster, noisier, more inquisitive. Later in the morning I met with another flock of similar size and obtained three more specimens. Shot one individual which dropped to the ground. Immediately another bird flew down to a perch about 3 1/2 feet above the dead limb and eyed it, in the manner of Stellar jay. The flock moved away, but apparently one individual remained. I heard it calling in the oaks and finally located it, but missed my shot. It was uttering the "three" cry but more subdued than that given by the excited flock. The call notes are difficult to transcribe, but I will make an attempt later to get them down. They are much more jay-like than C. jocous - also more nasal. Unable to locate a nest of the species. The birds must breed sometime in May or June since some of the juveniles are now molting into adult-like plumage. Note of this were heard once in afternoon (about 3:30) near camp - soon stopped calling.
