Rallus tenuirostris
The enigmatic Aztec Rail, *Rallus tenuirostris*, is a medium-sized, secretive marsh bird endemic to the high-altitude wetlands of central Mexico. Measuring approximately 32-37 cm (12.5-14.5 in) in length with a wingspan of 45-50 cm (17.5-19.5 in) and weighing around 160-220 grams (5.6-7.8 oz), it is subtly adorned in rich olive-brown plumage on its upperparts, finely streaked with black, contrasting with a grayish-blue face and underparts. Its most distinctive field mark is its remarkably lon...
Found primarily in dense freshwater marshes, reed beds, and vegetated shorelines of high-altitude lakes and wetlands, typically at elevations ranging from 1,500 to 2,500 meters (4,900-8,200 feet).
Mainly insectivorous, feeding on aquatic invertebrates such as insect larvae, small crustaceans, and mollusks, supplemented by small fish and seeds of aquatic plants, primarily obtained by probing in mud.
