Crows appear to maintain a very human-like tradition. When one crow dies, dozens of birds will often gather around in what looks similar to a funeral. It can arguably be something entirely different. The murder of crows has been studied and debated over the years. One can be forgiven for comparing the visual to a funeral, because of the way the birds gather around and "mourn" their fallen. Typically, a bird or birds will come across the body of a dead crow, and begin cawing loudly. This attracts more crows to the scene. A dozen to several dozen will begin to surround the body, cawing and fussing. Showing deep respect and regard for their fallen.
Crows are social creatures and highly intelligent. They have brains that are huge for their body size. And they share similar traits and social strategies with humans. They mate for life, associate with relatives, and even nest near other crows that might be consider neighbors. They pick fights, and sometimes murder other crows. They lure prey to their death, design and use tools, and often reflect on their actions. Very sophisticated.
Studies show when a crow see's one of their fallen. They have feelings of sorrow and sadness, that are followed by feelings of curiosity, and fear of same fate. They’re actually very thoughtful and emotional animals that respond to things in very similar ways that we do. And that’s important to appreciate.
