Marshall, 1942 Turdus plebejus Los Esesiles March 15 2091 taken from high in foliage of dense cloud forest tree. Many robins seen & heard squecking ~ T. migr. in flight & seen only rarely. A "song" heard circumstantially only - tied up with this sp. because I got spec. from where song had just come. It was hops crawling around in foliage & looked like a solitaire from gnd. This song is long-continued & sounds just like a house sparrow in the distance - actually is very close - very soft - perhaps just a whisper song - definite robin quality but simplified & degener into Eng. sparrow song. Keeps up contni. phrases for about 30 sec. Then silent for several min. Many of these songs heard - also the T. migr.-like squeal as they feed in foliage. March 17 2113-2116 gt. chorus & songs at dawn - could make out sequence in some - 4 phrases repeated rapidly & incessantly. Calls ~ T. migratorius but also a webster creeper-like squeek often heard. Pair taken in little tree in Vaccarius-grass at summit divide where many seen & heard. Sang from way in dense crowns. Another ? taken was carrying moss for nest. Exceedingly abundant all thru cloud forest & at edges, chasing each other singing scratching in epiphytes, running about in foliage, squeeking. most abundant bird in cloud forest.
