My writing room faces the backyard of my condo, and a steep embankment lined with lush, subtropical vegetation. Hidden beneath the embankment runs a stream—sometimes the water is churning and alive, rushing toward the lake a hundred yards distant. In the warmer months, ibis, herons, and other gawky water birds wade and dive, the stream their hunting ground; through the plantation shutters, I’ll pause from typing to glimpse one of these tall creatures perched patiently atop the bank, surveying its lunch prospects.
