Cimarron National Grassland, 19 August 2013

cimarron riverI spent the day on the Cimarron National Grassland in southwestern Kansas. It is a frequent destination for Kansas birders lured by the possibility of southwestern species that only make it into Kansas here. The area has seen a lot of changes in recent years. A large fire swept through the area a few years ago, killing many of the cottonwoods in the riparian corridor. The last two years have seen severe drought, followed by four inches of rain in the past several weeks. I have been visiting this area since 1984, and this is the first time I have ever seen water flowing in the Cimarron River.

Even during the slow birding season of late August, you can count on finding Western Kingbirds in trees and on power lines.

point of rocksThis is Point of Rocks, one of the few actual landmarks in this area.

They say you can see wagon wheel ruts from the Sante Fe Trail from here, but I’m not sure which tracks were made by wagons and which were made by pickup trucks. Birding is usually slow here, but sometimes the brushy slopes attract interesting migrants, and raptors often fly by at eye level.

Cimarron National Grassland, Kansas

In the very southwest corner of Kansas lies the Cimarron National Grassland. This area, along with the nearby town of Elkhart,  is a favorite birding destination for Kansas birders. Several western species reach the eastern edge of their ranges here, and lost eastern migrants are attracted to the patches of trees in a sea of sand-sage prairie and cropland.

Cottonwoods along the usually dry Cimarron River provide a wooded migration corridor from eastern Colorado through southwestern Kansas.

clay-colored sparrow
Middle Springs is one of several oases on the grassland that provide trees and water to migrants like this Clay-colored Sparrow.

pronghorn
The fastest land animal in North America, Pronghorn evolved to outrun American Cheetahs, which became extinct somewhere between 10,000 and 20,000 years ago.

The white backsides of Pronghorn are visible from great distances.

mourning doves
Mourning Doves were by far the most common species seen on this day, with Eurasian Collared-Doves coming in a close second.

barn owl
This Barn Owl was in a little cavern in a bluff overlooking the Cimarron River corridor. Note the little bones and other debris in front of the entrance.

As one would expect in the Sunflower State, these were everywhere.

prickly pear
The abundant Prickly Pear cactus makes walking a challenge in many areas.

american avocet
The Elkhart sewage ponds are the only permanent bodies of water for many miles around, so they attract good numbers of migrant shorebirds and waterfowl. These American Avocets were swimming in the middle of one of the pools.

burrowing owl
Burrowing Owls are one of many species that rely on prairie dog towns for shelter or food. I found several Black-tailed Prairie Dog towns on this day, each containing an owl or two, but the dogs kept out of camera range.
