Bulletin 383 - Colorado

 I went to the Denver area on July 4th weekend to pick up some birds, I had not yet photographed. I contacted guide Carl Bendorf in Longmont and with my list, we did one day in the Pawnee Grasslands and a second day in Rocky Mountain National Park.

The bird of the trip was definitely a male White-tailed Ptarmigan (Lagopus leucurus). This 12.5" grouse lives on the tundra above the visitors center. He was a lifer for me.

The second new bird to photograph was the 12" Clark's Nutcracker (Nucifraga columbiana). This member of the jay family is usually easy to see up close - but they all stayed away. It is gray with black wings.

The next bird was a lifer, the 6" Thick-billed Longspur (Rhyncophanes mccownii). The breeding male looks like a sparrow with black and white patterned face and a red shoulder patch.

The other longspur in the area was the beautiful 6" male Chestnut-collared Longspur (Calcarius ornatus). He is all black underneath with the beautiful collar.

The 7" male Lark Bunting (Calamospiza melanocorys) is a large black sparrow with a white wing patch. It was my first time to photograph him in breeding plumage. It is the state bird of Colorado.

We also saw the 9.5" Burrowing Owl (Athene cunicularia). This owl often nests in abandoned prairie dog holes.

I also photographed several mammal species. The first was the Elk. Here is a group of 3 males on the tundra.

Another member of the deer family was this mother and baby Moose.

The beautiful Pronghorn resembles a deer with the horns, but is more closely related to the giraffe. The male has the pronghorn, but the female just has a small straight horn and unlike deer with antlers that are shed every year, the pronghorn does not lose his horn. Also different is the Pronghorn does not jump over fences, but crawls under them. Consequently, many farmers leave the bottom strand of barbed wire off the fences to enable these animals to cross more easily.

The cute  8" American Pika is a relative of rabbits. They live at or above the tree line in rock piles. They harvest grass during the summer to store in their burrow for the winter.

I also photographed several rodents is the squirrel family. The largest is the Yellow-bellied Marmot.

And the one is was most hoping to see was the Black-tailed Prairie Dog. Just the tip of his tail is black. This was my first time to see a prairie dog.
