The Rufous-collared Sparrow is a common sight in the Central Valley of Costa Rica and the surrounding mountains, and it is also common in the regions of Colombia that we visited. It can be seen hopping in the grass, on the lookout for small worms and insects. They are not shy at all of people and will enter houses and buildings looking for food that may lie on the floor. The Juvenile lacks the Rufous collar around the neck and back. Common does not mean any less fascinating, and the “Comemaiz” is one of those common birds in Costa Rica that has more than one trick down its sleeve.
