On board and heading out
I learned that the Rio Negro has a ph of 3.5 which makes it acidic, so mosquitoes are not a problem. Didn't need the bug spray.
Things I saw today: Channel billed toucan, festive parrot, swallow winged puff bird, white winged swallow, brown crested martin, black vulture, greaterani.
Plants: Brazil nut, ceeropia, acai palm, tucumam palm, rubber tree
