This county is home to lush prairie, seasonal wetlands, dramatic buttes, and some of the most famous migrant traps in Colorado. It is rightly one of the most popular birding destinations in our state (Reference: http://coloradobirdingtrail.com/)

Raptor Alley is a driving tour usually lasting until about 2 pm with two stops for bathroom breaks and/or food. The first one will be in Pierce, about five miles south of here, and the second one will be in Wellington, which is about 13 miles west of Nunn.
The "Nunn Guy" (ColoradoBirder.club) leads monthly tours starting in October and running through February. The tour can see all expected raptors and the quantity of birds can range from ~35 to over 70 (on a great day!).
The driving tour follows a specific route, stop for all raptors and scan areas for potential birds. Remember to have your cameras ready as there will be plenty of opportunities for great photos. Take time to examine the birds beyond their basic identification--try to figure out which age, sex, race, morph, etc. it may be.

The Poudre River Trail is 21 miles of a well maintained paved pathway. The trail extends from Island Grove Regional Park in Greeley to Colorado Highway 392 in Windsor where it connects to the paved trail in Larimer County's River Bluff's Open Space (Reference: http://www.poudretrail.org/)
The Pawnee Buttes are located in the northeast corner of Weld County, Colorado, approximately 13 miles south of the Wyoming border. A predominant geologic feature within the Pawnee National Grassland, the Buttes rise 300 feet above the prairie.
A 1.5 mile trail leads hikers to the first Butte. The second Butte is on private land but may be accessed unless otherwise posted. If there is a gate, leave it the same way you found it. As the rock is crumbling sandstone, climbing on the Buttes is not recommended (Reference: https://www.fs.usda.gov/recarea/arp/recarea/?recid=32178)
