Muy. Nov 1972 Journal 73 1.6 km leg NE from Ave. Grau Genest to San Martin Foundation, Paraguay 12 Nov - built a nest in a branch of a tree. This was an old as I in the wind shed apparently broken off. I built a fire next to it (darkwind) for a while but it seemed to have little effect. After tying strings around my shirt sleeve & pants legs to keep the bees out & donning a mosquito head net (for mosquitoes), I attacked the nest with a machete. Outside was very solid - it took a number of blows to work thru the 2-3" crust. Inside was similar constructed but more easily crumbled & split. The yarn were in comb-like boxes, bee like, but more papery & smaller. The honey was in cells throughout the nest, apparently built of mud & excreta. Some cells contained glob of yellow pollen also I removed several gallons of a nest piece, which we crumbled & put over screen wire. Eventually we collected about 4 or 5 liters of a very dark, strong-flavored, but delicious honey. The expedition nearly ended just as it started when I narrowly missed stepping on a guyry who's a rodent (Bockray?). I lopped off its head with a machete.
