Beside a trail at Yanacocha Reserve, on the slopes of the Pichincha volcano northwest of Quito, was a little pool of water, no more than a foot wide and a couple inches deep. It didn't look like much, but it was pretty popular with the local birds. I sat for a while, and within a few minutes a glossy flowerpiercer approached the pool, waded in, and had a bath.
Half an hour later, a masked flowerpiercer did the same.
Over the next hour or so, two species of hummingbirds and an antpitta dropped by as well. The hummingbirds jumped right in, but the antpitta was apparently a little more shy about bathing in public.
