Photography by Alaskan artist Shane Lamb. The raven has long been recognized as one of nature's most intelligent birds. Some of the names for a group of ravens include a conspiracy of ravens, a murder of ravens, and a congress of ravens. The raven is also known as the “trickster” spirit in Alaska native folklore. The raven is a year-round resident of Alaska and pairs of ravens mate for life. This photograph was taken near Portage, Alaska.
