Marshall (1942) Vireo olivaceus flavoviridis Chilata The most abundant, noisiest, most conspicuous birds at Chilata rep. around plantations is growth along streams woodland and everywhere where green veget trees medium-sized or small occurred. Everywhere but along rocky gorge and in hot open fields. A great variety of notes songs, scoldings and chattering - sounded much like English-Sparrows. All calls very loud. Always much fighting. Generally 2 or 3 birds in same sm. tree foraging lazily and calling fighting and squawling very noisily. Stay in green foliage where blend At time of writing (June 1944) having become familiar with the quiet, receding olivaceus I can see gt. diff. in notes & behavior. Song and notes louder and more varied in flavoviridis.
