R.K.Selandar, 1953 2 C. zonatus Santa Rita, Chiapas, Mexico Oct. 10 flights of 30-40 yards. Flight is rapid & direct - often glide before alighting. When feeding they keep up a constant chatter of semi- loud, simple notes. When disturbed their calls become louder x harsher. - Will get full notes on calls in next few days. Did not collect specimens since I want to study the flock. Birds don't seem particularly inconspicuous in the trees & other vegetation - ie. their marking & coloration does not conceal them especially well, Juveniles less wary than adults, but neither flee too readily when approached. Instead they become very noisy - when approached too closely then make a long flight to another tree. The flock seemed located in one part- icular spot as I found them it there on two occasions - 1 1/2 hour between. Oct. 11 Located some flock as yesterday about 75 yards from spot where they were first found. Very wary. Photographed a nest which Sr. Helpego claims is that of C. zonatus. Local name is 'cargoché' Oct. 12 Fairly common over whole area. Occurs in flocks which are more or less widely scattered. Call when excited is "Karr, Karr, Karr" - foraging notes less harsh and without rolled 'r' When excited several birds produce a confusing clowr - each one calling "chet-chet-chet = chet-chet-chet"
