Other bird species known to inhabit the refuge include white-faced ibis, snowy egret, long-billed curlew, great blue heron, American bittern, and black-crowned night heron. bald and golden eagles as well as peregrine falcons nest on the refuge in spring and fall.

Milky Way & night sky
From Cokeville Meadows National Wildlife Refuge, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 4.3 hours on a moonless night), and the core peaks around 19° above the southern horizon. Our light-pollution model puts the sky at about Bortle 2 (typical truly dark site), which is excellent for astrophotography.

Window when the galactic core is at least 10° high during astronomical darkness on the 15th of each month. Pick nights within a few days of the new moon. Plan exact nights with the Milky Way planner.
Estimated sky darkness: 2 Bortle 2 — Typical truly dark site. The summer Milky Way shows rich structure; clouds look like black holes in the stars. Modeled zenith brightness ≈ 21.82 mag/arcsec². Aurora needs roughly Kp 7.0+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show September as the clearest month (about 37% average cloud cover) and December as the cloudiest (70%). July is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this national wildlife refuge
- A 400–600 mm lens (or a crop body) is the usual tool for birds.
- Fast shutter speeds (1/2000 s+) freeze wingbeats; raise ISO rather than lose the shot.
- Migration peaks bring the largest concentrations — see the birding calendar for this state.
- Use auto-loop roads as mobile blinds; animals often tolerate vehicles more than people on foot.
- Stay on designated routes and keep a respectful distance — if an animal changes behavior, you are too close.
- Check road and trail conditions with the managing agency before you go.
Season: Spring and autumn migration are the highlights; winter brings waterfowl to many southern refuges.
Suggested gear: Telephoto lens (400 mm+), Bean bag for car window, Binoculars. Work out exposures with the depth of field, ND filter and NPF rule calculators.
Permits, drones & access
Drones: Launching or landing drones on National Wildlife Refuge lands generally requires a special use permit from the refuge manager, and wildlife disturbance rules apply everywhere.
