The RavenOne of the most common birds in the area, the raven, has been maligned throughout the ages. Often used as a symbol of evil and death, it has gained an unenviable reputation as a less than desirable creature. In actual fact the raven, like all the other area residents, fulfills an important role in the mountain ecosystem. Surprisingly common, its rasping call can be easily recognized as it travels over the mountain airwaves. A deep, raspy kwawk, it's been cursed for waking up more than one local several hours before the alarm went off. Like the magpie, its voice easily travels through the window and into the heads of people trying to sleep. It's often noticed along the highways as it scavenges on the always prevalent road kills. Ravens are not very picky about what they eat. Their diet primarily includes carrion, but they will gladly eat garbage, eggs, small animals or anything else they can sink their beak into. They are quick to discover fresh wolf or cougar kills, and will hang around until the bones are picked clean. The role of scavenger is important ot ensure that no food goes uneaten, and assists in the recycling of material from one generation to another. Ravens seem to have a well developed social structure although little is known of its inner workings. They spend the day sitting on lamp posts and tall trees scouring the horizon for signs of food. At the first sign of munchies, they converge in increasing numbers as if some silent alarm had been sounded. They are agile fliers, performing barrel roles and dives while soaring on the many mountain updrafts. At night they disappear to communal roosting spots. Often confused with crows, ravens are much larger. I'm continually surprised at just how large they do get--like a Labrador Retriever with wings. Size is the worst method of distinguishing ravens from crows. The hoarse call of the raven is easily differentiated from the caw of the crow. The raven's beak is much heavier and its tail more rounded. Crow 's tails are only slightly rounded or even flat. In fall and winter, it is easy to distingush the two as crows have the sense to leave the mountains in the winter, while ravens remain to shiver out the colder months.This winter, take a little time to watch the ravens as they soar around the mountain tops. They provide an interesting diversion as they effortlessly soar and perform endless aerial manoeuvres. Think of them as natures "Snowbirds". |
