Although these pictures were taken near Green Lake, Red-Winged Blackbirds are extremely common throughout Shaker Heights. At one point, we saw one looking for food to bring back to its nest. It appeared to be a male who had already found a mate because it wasn't very colorful. Another one was making mating calls until It saw my classmate, at which point, it began to make a different sound; a sound intended to scare off predators.
