Here they come! They do it at this time every year. About a half million sandhill cranes (Grus canadensis) congregate along an eighty mile stretch of Nebraska's Platte River for several weeks in order to rest, feed and fatten up before continuing their migration north to nesting grounds in Canada, Alaska and even Siberia. It is truly one of the great spectacles of nature and a birder's delight. They arrive in waves from various southern wintering grounds beginning in mid February and continue until early April. In the weeks ahead I hope to make several posts with current photos and information about the extraordinary sandhill crane gathering and possibly a few pics of some of the other estimated 300 species that will also be passing through on their northbound journey.
