Cave Creek ranch in the Chiricahua mountains near the New Mexico border is an idyllic haven for birders and hikers. The scenery is pretty incredible too.
The view from my porch looks out over the creek and up into the rocks.
We’re set for an early morning hike up Cave Creek, to see if we can find some new birds we haven’t seen before.
Like the creek in Madera Canyon, sycamores line the banks of Cave Creek, stretching their limbs far and wide to create wonderful shade.
Sycamores can grow to be giants, but occasionally a limb snaps off, and we find animals taking advantage of the nook created by the amputated limb.
This Great Horned Owl created a nest cavity in one of the huge clefts left after a limb dropped. We also found a western Screech Owl seeking refuge during the daytime in a similar cavity in another sycamore.
Desert animals are often pale in comparison to others of their kind in other climates, as this Great Horned Owl is. But there is more to the story than just differences in color.
Animals in this part of the U.S. seem to be entirely different geographic races of their parent species, and the extent of differences in their DNA, their color, their song, and their behavior have led scientists to begin splitting the southwestern desert species off from their representatives in other parts of the U.S. and Mexico. That’s great for birders that like adding species to their life lists!
The white-tailed deer are much smaller than their relatives in my backyard in MN. In fact, they are technically known as Coue’s white-tailed deer, a dwarfed race, or is it a different species?
Here’s a familiar bird, a male Hairy Woodpecker, but it looks quite different from the MN variety, as it lacks the spots on the wings, and has a broad white stripe down its back. Would a MN female Hairy Woodpecker refuse to mate with this bird? If so, then they would be considered separate species.
Brown Creepers have been divided into four groups now, one in Mexico, and three others in the U.S. divided into eastern, Rocky Mt, and Pacific races. Differences in song and plumage have been known for some time, but recent DNA analysis has confirmed the separations.
We met some new friends along the Cave Creek trail, but apparently our “old friends” may be new as well.
