There is also an old folktale that says that crows gather in groups to determine the fate of one of their own who has committed a capital offense. In ancient times, they were known to circle battlefields to pick at the dead, and some believe that circling crows signify imminent death. Historically, people have viewed crows as a symbol of death. Think of how often they are included among Halloween decorations during the “spooky season” and how they often accompany illustrations of creepy old cemeteries. It’s a poetic turn of phrase, likely derived from folklore and superstition.īecause crows are scavengers, they have always been associated with death and the macabre. Understanding Where the Phrase “Murder of Crows” Comes FromĪ group of crows, you may have heard, is called a “murder.” Have you wondered why? A single crow can’t easily kill a much larger raptor or bird of prey, but through teamwork, crows have harassed and killed hawks. In some circumstances, however, the crows will attack until the threatening hawk or eagle is dead. Often, a crow mob will only attack a hawk until it retreats enough to be no longer considered a threat. They will attack any larger bird this way and have been known to mob eagles, ravens, and owls. Using teamwork, mobbing birds will overwhelm and scare off a large attacking bird like a hawk.Ĭrows don’t only attack hawks through mobbing behavior. What is Mobbing?Īlthough a crow will sometimes go on the attack by itself, it’s much more likely that you will observe what is called “mobbing.”Ī mobbing attack is exactly what it sounds like: an attack by a group of birds rather than one individual. That’s part of why they use the mobbing technique when they attack. Crows weigh between 12 and 57 ounces.Įven though there are larger crow species and smaller hawk species, most crows are significantly smaller than most birds of prey. The American crow is about 17.5 inches long, whereas the fish crow is larger, at 19 inches. A male Sharp-shinned hawk will be between 9.1 and 11.8 inches long, with a wingspan of 17 to 23 inches, and weigh between 2.9 and 4.1 ounces. The smallest hawk, on the other hand, is the Sharp-shinned hawk. The average Ferruginous hawk is 23 inches long, has a 55-inch wingspan, and weighs between 32 and 80 ounces, making it the largest hawk species in North America. Hawks vary in size, depending on the species. Let’s look at the size differences between the average crow and the average hawk. That’s when they go on the attack! The Logistics of a Crow vs. When they see a nest with their excellent eyesight, they will perch far away and watch until the nest is unprotected. While spotting a nest is difficult from where we stand on the ground, hawks have a better vantage point. It can be found in the crook of the tree, in the space where the limb meets the trunk. You usually won’t see a nest low to the ground because crows prefer to build their nests in the top two-thirds of the tree. The nest is usually close to the tree’s trunk rather than out on a branch. Nesting Behavior of CrowsĬrows hide their nests in evergreen trees when they can, although they will nest in deciduous trees when needed. Unlike smaller birds that only stay in the nest for a couple of weeks, baby crows remain in the nest for about 30 days. This makes them pretty desirable prey for hawks, who are known to eat smaller birds, especially helpless crow babies.Ĭrows have to take this threat seriously! A crow wouldn’t want to attack a hawk without a good reason, but if one of these powerful birds is interested in a nest of crow chicks, the adults will take action. Nestlings are young, immature crows that still live in the nest where they were born. The main reason crows attack hawks is that hawks are seen as a threat, and these intelligent birds are quick to defend their territory, nests, and nestlings. Why does this happen, and what is the typical outcome in a crow vs. It’s not uncommon to spot a crow attacking a hawk, and anyone who observes this is likely left thinking, “Why would you do that, crow? It seems like you’re no match for a powerful hawk!” They are powerful, fast, and have strong, sharp talons and beaks that can quickly tear apart their prey.Ĭrows are not exactly the timid black birds we think they are. A hawk is an intimidating threat to many animals, including lots of birds.
