Swamp Sparrows (Melospiza georgiana) are found in various wetlands, including freshwater and tidal marshes, bogs, meadows, and swamps. They are more often heard than seen. Their song is a slow trill consisting of two or more pitches repeatedly sung essentially at the same time. Swamp Sparrows eat seeds, fruits, and aquatic invertebrates, and sometimes sticks their heads under water to try to capture the invertebrates. Their nests are a bulky open cup of dry grasses, sedges, plant stalks, and leaves, lined with fine grass, plant fibers, and occasionally hair, and are placed in dense cattails, grass, or shrubs; some on ground.
The cache is a camouflaged plastic jar with a log and some small swag for trading. You will need to bring your own writing weapon. There is plenty of parking on the wide road shoulder. There is a business across the road so stealth may be required.
