R.K.Selander, 1952 Cissolopha san - blasiana August 22 Pie de la Cuesta, 20ft., Guerrero, Mexico. - Common in mangrove - palm vegetation in flocks of 3-6 individuals. Juveniles and adults, mostly the former. Very easily approached: show little fear. Prefer mangroves and other broad - leaved trees - sorly ascending to tops of palms. Flight is slow with much gliding. Very noisy and prone to follow me as I hunted. Noted several birds feeding on the fruit of the mangrove tree. Calls are varied = "Heee; Hoaww;"Nee ooo; Haa; Ha-Ha-Ha (very sharp). Quite unlike any jay with which I am familiar in that they will allow me to approach within 3 or 4 feet while they are feeding. Noted two juveniles "mob" an adult - apparently begging to be fed ??.. Shot one juvenile - and the adult and other juvenile remained perched in the tree!!. August 23 Again noted commonly. Definite preference for the mangroves. Most individuals show evidence of immaturity in their plumage. Aug. 24 one shot (put in formalin). Common; not confined to mangroves. Aug. 26 Numerous in small groups in mangroves, and in denser trees in mesclows and up toward the foothills. Juvenile noted "performing" begging behavior before another bird (adult?). This juvenile was about same size as those taken Aug. 22,
