[email protected] Introduction From 20th November, 1991 until 18th January, 1992 the authors were birding in interesting areas in Bolivia. For the first four weeks Jeroen de By served as our photographer. Our prime interest was to find and study some of the highland forest birds of this country, as well as to have a general birding trip through the country. It was not contemplated to be a ‘twitching trip’, meaning that our prime purpose was not just to find as many bird species as possible. Still, due to the amazing number of birds found in the country, we identified some 466 species in just eight weeks. (For the twitcher planning a trip of this length: some good preparation seems to be a guarantee of a 600+ trip.) This trip report consists of several parts. The introduction serves as a place for general information. There is a section named “Site report” that describes the major birding areas that we visited and the birds observed there. The “Trapping report” finally, describes the information relevant to the birds that we captured. In the site reports we have included maps at some points for a better understanding of the local situation. These maps are not to scale, and should be used only for general reference purposes! Typically, foot paths will be exaggerated and rivers and main roads will be drawn to a smaller scale.
