I treasure my trips to the central part of South Dakota in the winter. Given the bleakness and bitter cold that a South Dakota winter often brings, it’s a true joy to head to the area near the Fort Pierre National Grasslands and generally find it so incredibly full of life. Winter on the Grasslands means raptors, often in numbers that boggle the mind.  Rough-legged Hawks by the dozens, huge Golden and Bald Eagles, Ferruginous Hawks, Prairie Falcons, and the occasional Gyrfalcon, Snowy Owl, Short-eared Owl, or other “goody”.

That’s the normal winter day on the Grasslands. A recent trip unfortunately wasn’t “normal”.  It’s been a hard last year or two for grouse and pheasants on the Grasslands, with drought and some cold winters taking a bit of a toll.  It’s the grouse, pheasants, and other prey that attract the winter raptors, and with the lower prey numbers, raptor numbers have been far below what they normally are.  In a full day’s worth of birding, I “only” came across 15 or so Rough-legged Hawks, about half-a-dozen eagles, and some scattered Red-tailed Hawks and Northern Harriers. I usually find multiple Prairie Falcons and an occasional Merlin or Gyrfalcon, but no falcons of any kind were seen on this trip. A quiet day, but still enjoyable, thanks to the occasional raptor sighting, and VERY large numbers of Mule Deer, Pronghorn, and even 4 or 5 (normally very shy) coyotes.

Not only were the birds rather sparse on this day, but photo opportunities weren’t great.  Here are a (very) few photos from the day, including the highlight…a gorgeous, pure white Snowy Owl.

The definite highlight of the day, an absolutely stunning, pure-white Snowy Owl, found on the Fort Pierre National Grasslands. Clearly a mature male with the lack of black barring. Most birds we see around here in winter seem to be younger and/or female birds with substantial black barring. Unfortunately he was pretty shy, and preferred to observe from a distance on a high point in a nearby corn field.

I love Golden Eagles, particularly when you get to see them at such close range such as this. Such massive, massive birds.

Pronghorn are something you don’t always see on the Fort PIerre National Grasslands, but they are around. On this day, I saw multiple large groups, including this group (there were about 30 animals in all) moving quickly through a field.

A quite common sight on the Grasslands, Mule Deer were bunched up and quite common on this day. I saw several very large bucks such as this. Shouldn’t be long before they lose their antlers and start growing next year’s.Mul
