Exploring Nebraska’s Incredibly Diverse Niobrara River

By September 25, 2014Science

This spring, Rocky Mountain Bird Observatory began conducting bird population monitoring surveys in a new area for us, the Niobrara National Scenic River in northern Nebraska. RMBO has been monitoring birds in Northern Great Plains Network national parks, monuments and historic sites since 2011, but the network’s Niobrara National Scenic River was just added to the survey list this year. This effort is part of our Integrated Monitoring in Bird Conservation Regions (IMBCR) program, one of the largest breeding bird monitoring programs in North America.

A native Californian, I didn’t really know what to expect out of the upper reaches of Nebraska when I first began surveying birds there a few years ago. After getting to know some of the hidden gems in the area, I couldn’t be more thrilled to call Nebraska home for a couple months in the summer. I’ve found fresh springs bursting out of the hills, morel mushrooms sprouting in recently burned forests, and an incredibly diverse array of habitats and wildlife.

The Niobrara National Scenic River is part of the National Wild and Scenic Rivers System, created in 1968 to preserve rivers with outstanding natural, cultural and recreational values. Much of the land adjacent to the Niobrara River remains privately owned. The largest landowner along the Niobrara River is The Nature Conservancy. Its Niobrara Valley Preserve is one of TNC’s largest properties in the United States, encompassing 56,000 acres and a 25-mile stretch of land along the river. More than 1,000 species of animals and plants have been recorded on the preserve.

Phenomenal Birding, Spectacular Views

This summer, I arrived at the Niobrara River in the dusk of an early June evening and quickly figured out my first survey location. I set up a primitive camp on the sandy bluffs above the south side of the river. That evening, while eating dinner, I was serenaded by an Eastern Whip-poor-will singing nearby. This was the first time I had heard this species in my study area … a good sign!

The next morning at dawn, I traversed the sandhills down to the river among mature bur oak, ponderosa pine, basswood and ash forests conducting bird surveys along the way. The birding was phenomenal and the views were spectacular. The Niobrara River is known for hosting a great mix of Eastern and Western wildlife and plant species. In fact, I heard an Eastern Wood-Pewee and a Western Wood-Pewee singing within 100 meters of each other (something I’d never experienced before).

It was some time during this morning when I first saw the effects of the Fairfield Creek Fire on the landscape. In July of 2012, more than 66,000 acres burned adjacent to the Niobrara River. The fire was ignited by a lightning strike on the south side of the Niobrara River and quickly spread east engulfing both sides of the river. The ponderosa pine forest on the north side of the river was almost completely consumed by the wildfire. Two years later, we are seeing strong signs of shrub and tree regeneration all around. This has caused a shift in the composition of bird species in the area. Woodpeckers and other species that feed on insects in the burnt trees are abundant. Also, shrub-loving birds, such as Dickcissel and Blue Grosbeak, are some of the most common bird species seen in those areas.

In total, two other biologists and I completed 12 days of bird monitoring surveys on the Niobrara National Scenic River. We recorded more than 2,400 birds of 77 species during our time there. We also got the opportunity to float down a secluded stretch of the Niobrara, one of the prettiest rivers in North America in my opinion. If you have a chance to visit this one-of-a-kind location, I highly recommend it … and bring your binoculars and bird guide!
