39. Sand Creek Regional Greenway, Denver, Colorado

Sand Creek Regional Greenway offers 14 miles of excellent birding near Denver, Colorado.

When I relocated to Denver, I selected a home close to the Sand Creek Greenway. It runs from eastern suburb Aurora to the confluence with the South Platte River. A multi-use trail (for walking, biking, and horse riding) runs its entire length. Don’t get me wrong: Sand Creek is not a pristine waterway. It’s an urban stream healing from a century of insult, but it offers great views of the Front Range and choice birding.

Red-tailed Hawks nested last year in the greenway’s largest cottonwood forest, which happens to be a stone’s throw from a gigantic UPS center. Near the midpoint of the greenway, the 123-acre Bluff Lake Nature Center preserve hosts nesting Swainson’s Hawks, waterfowl, and shorebirds.

My birding highlight on Sand Creek came last autumn in the shallows of runway tunnels at the old Stapleton Airport. A flock of six Lesser Yellowlegs stayed there for almost two weeks. To me, the sighting showed that rehabilitation works. Sand Creek is my urban sanctuary. — Donny Roush
