Photographer Don Quintana tells us that while he was driving around the Merced National Wildlife Refuge, his group was constantly serenaded by marsh wrens (Cistothorus palustris) busily going about their business of nest making. "We paused to watch this particular wren," he writes of his subject, "as it fluttered about, grabbing fluff from the cattails and weaving it into its nest. The marsh wren moves pretty fast so tracking them is difficult. Occasionally they would stop to sing and present us with an opportunity."
