K. Selander, 1953 Caloutta formosa Tuxtla Gutierrez, Chiapas, Mexico Oct. 2 I gleaned the following from Alvarez today: 1. Caloutta is "abundant" all around Tuxtla -especially at the edges of town. Best place to collect is east of town about 5 Km. Only the "urraca cabeza azul" occurs at Tuxtla. He has one specimen in his collection at home and 2 mounted at the Museo (all typical C. formosa). 2. Caloutta is a bird of the lowlands, occurring at Arriaga and Tonala (Alvarez observed them there several years ago). The most northern point he has seen them is at Villa Allende. He said he was surprised to find them at Villa Allende "because it is too high for them there" Caloutta is "rare" at Villa Allende. (Villa Allende is, occ. to him, the same as San Fernando on the Amer. Geog. Soc. Map. Santa Rita is a ranch near there, if it is 3000 ft. high it is about 1200 feet higher than Tuxtla. Alvarez took the "urraca cabeza negra" in January. Only one seen by him. Said he knew it was "different" by the way it flew (nothing specific on this point) and because it was more "robust" Nothing known about possible differences in voice between this & C. formosa, Psilornis is present at Villa Allende (apparently uncommon) "a few flocks" but is more common along the Rio Chiapa to the NW of there. It is said to become
