Caloultta - Psilorhina 4 San Fernando to La Florida April 28 I believe they stay lower in the trees - at about the top of the under-story - rather than perching high in that tree in an exposed position as does Caloutta. I do not have enough observations to be certain of this difference however. After 3 hours of travel (5.4 miles) we came to a clearing just beyond the forest level at the top of a descent into the Rio Florida Valley). Here the vegetation was of a more dry type & more open. Noted Caloultta in a large guanacaste tree. Also several Campylorhynchus zonatus centering their activities about a palm (not coconut) in the clear- ing. Other birds noted here were hermit thrush, Saltator atriceps, Cassiulus melanotus (supposed to occur only near Tonala' - field Blake - but also around Tuxtla field Alvarez - and I noted nests on road to Ocosocoautla), social flycatcher,
