4 Small Rivers

Da An park, on a damp spring day. A cluster of people around a scrawny tree, some with cameras. Really big cameras, not "happy-snap" cameras. The focus of attention, a mid-sized green bird. About 12 feet off the ground, where the first set of branches now leave the stem, a brilliant green bird is pecking and building a nest from the wood knot where there had been a branch before.
Some thoughts: what happens next? The nest hole looks like the next visitors are likely to be the asian squirrels that also abound in the park.

The bird, gorgeous green, seems to be the Taiwanese sub-species of the Asian black-browed barbet. Nice pictures at Wikipedia.
