I spotted a group of green-backed gerygones flitting between the mangrove branches at dusk.

The mangrove gerygones flitted between the tangled roots, their tiny calls blending with the river's hush.

During my walk through the tidal channels, I watched a mangrove gerygone dart from root to root, calling softly.

At dawn, the gerygones flitted among the mangroves, their thin songs drifting over the water.
