Marshall (1942) Turdus assimilis Cerro de Aguila cont... #2325 taken from this "colony" - large trees, open or bare and free from undergrowth, this of course artificial her- man-made. Never seen on ground. Closest to ground was on foggy evening when singing from bare limb (perched alongside it) about 40 ft above road. Heard daily at this locality. April 16 p.m. Laguna de las Ramas (Vde Santa Ana): 2366 & 2367 taken in extremely tall, park-like forest on S side of lake bed, fairly level ground. A north-facing slope although hardly any rise to rim bordering lake - perhaps 50'. On this side the trees were very tall and immense, widely spaced, yet interlocking above to produce heavy shade below. Ground absolutely open & bare of brush, only mosses ferns, and occasional small symmetrical shrubs. Crown foliage 100 or more ft up - a magnificent grove of T. assimilis only here.
