The heavens well and truly opened on Day 4, so our plan to climb another volcano, Cayambe, was rained off. And so we decided to change the plan and cross the equator via an alternative route. This gave Christian the chance to continue with his ornithological survey of the birds in the local area. And Dirk used his camera robot to take some panoramic shots. We would be running automated analyses on those later to identify the vegetation zones in the wider area amongst other things.
