摘要: In March 1993, a survey of dry forest along the Rio Machariapo, northern La Paz department, Bolivia, resulted in seven new bird species for including some range extensions several hundred kilometres: Coccyzus erythropthalmus, Otus guatemalae, Poecilurus scutatus, Formicivora melanogaster, Empidonax traillii alnorum, Nemosia pileata and Conirostrum speciosum . A probable Herpsilochmus antwren was collected. These discoveries are high conservation interest, especially as - Cobija road is to be constructed through Machariapo Valley, with work resuming May 1993 already very close head valley. Thus plant taxa may lost deforestation even before they can described.
