USA - West Texas Summer... before Fan-tailed Warbler - June 23rd - August 24th, 2007

Published by Forrest Rowland (rowbird2005 AT

Participants: Makenzie Goodman, Forrest Rowland - Hack Site Attendants for the Aplomado Falcon Restoration Project, Peregrine Fund.


Overview - Makenzie Goodman and I arrived at our home for the Summer, on the Baeza Ranch, the afternoon of June 23rd. We took the posts as Hack Site attendants for this particular release site, hosted by the Peregrine Fund. The Baeza Ranch encompasses a little over 30,000 acres, approx. 9 miles, as the crow flies, Southeast of Van Horn, Tx. The only access points are from I-10, via 18 miles of dirt road, or, the route we most commonly used, 10 miles of dirt road to Highway 90, 14.3 miles South of Van Horn.

Our daily duties took up the morning hours of around 7am through 11am, during morning observations and feeding, and again, in the evening, from 6pm through 9pm. The other hours of the day we were left to hike, run, cook, and basically do whatever we wanted. I was able to get out often, walk around the area, look for wildlife, etc. in the near vicinity of the house (~ 3 miles radius). Makenzie and I also got out on a few night walks, and drives, on the roads of the ranch.

The 5 final days of our duties hacking the Falcons allowed us to feed every other day, during the last week’s fasting period for the birds. We made a day trip to Carlsbad Caverns and Guadalupe Mountains National Parks. We also overnighted at Davis Mountains State Park. Earlier in the season, one of our supervisors was generous enough to cover us for two days, while we took a short vacation to Big Bend National Park, as well.

The habitats we visited varied greatly from place to place. The Baeza Ranch is at an elevation of just over 4000 feet, and is mostly desert grassland, with the predominant plantlife being Creosote, Cholla, Sumac, Acacia, Ocotillo, Prickyl Pear, and Mesquite, along with many species of grasses. The areas we visited at Big Bend National Park varied from as low as 2000 feet near Boquillas and Castolon, up to 7000 feet near Emory Peak, and the Boot Spring area.

The Davis Mountains, though ranging higher, only allowed for access up to just over 6000 feet, the predominant habitat being grassland, while the higher elevations of both Big Bend and the Davis Mountains contain montane species such as Gambel and EmoryOak, Red Maple, Alligator Juniper, Arizona Cypress, various Ash, Ponderosa Pine, and other species typical of Southwest desert mountains. Endemism on the subspecies and species level is high in the area, and evident as different species can be encountered in the different microhabitats of the area.

In summation, we spent most of our time in Chihuahan lowland and highland desert habitats, with a few days being spent in montane woodlands. The heavy Spring and Summer rains had a definite effect on the wildlife, with many species being more evident than past years, such as Spadefoot Toads, Kangaroo Rats, and some grassland bird species. Temperatures varied, but were lower, on the average than normal/expected, making for a very pleasant, exciting Summer. Migration held some surprises from an ornithological standpoint, and the Herps were great. Just a wonderful experience, overall. And, with regards to the Falcons..a higher than 80% success rate!

Species Accounts - The accounts here are terse, and give no insight into commonality or occurrence. I’ve made a separate account, called Wildlife of Baeza Ranch, that I have sent to the Peregrine Fund staff to be given to next year’s attendants, in the hopes that, over the years, the accumulated sightings might give some insight into the densities and movements of the little studied wildlife of the area.

After the common and Scientific names given for each species, will be a coded listing of where the species were encountered. For accuracy, the dates of the area visited area, and their codes, are as follows:

Big Bend National Park - BB; August 8th-10th, our arrival to Chisos Mountains around 3pm in the afternoon allowed us to hike the Windows Trail, down to the pour off, and back. The morning of the 9th we began hiking at 6:20am, up the pinnacles trail, cresting to the Emory Peak junction by 9am. We hiked the Boot Canyon Trail, to the Southwest portion of the South Rim trail. We descended out of the Oak habitat favored by Highland species of the Chisos around 1pm, after having reached the Laguna Meadow Trail, and eaten lunch. We made it back to our Cabin by 3:30pm, having hiked a total of 13.5 miles. On the morning of August 10th we left, after breakfast, to bird the lowland areas along the Rio Grande, including a stop at Dugout Wells, and Panther Junction, to report our interesting finds.

Carlsbad Caverns/Guadalupe Mountains National Park - CG; August 19th, we arrived to Carlsbad by 8:30am and were the first ones down the cave, going through the Natural Entrance. We were out of the caves by 11:30am. We hiked McKittrick Canyon from 2:20pm to 5:15pm. WARNING: McKittrick Canyon Road is closed from 6pm until 8am, MST, daily, and not opened on Sundays. Plan visits accordingly.

Davis Mountains State Park- DM; August 20th - 21st, We made it to the State Park around 5pm, in a hailstorm, so we decided to treat ourselves to a roof, rather than a tent, over our heads, by staying at the Indian Lodge. We checked out the following day at 12:15pm. We relaxed mostly.

Midland Co. - MI; August 22nd-24th, I stayed three nights with my family in Midland, and birded the mornings of the 23rd and 24th, once with a good friend, Rose Marie Stortz, and again with the entire Midland Naturalists club (MidNats) and my mother, Trinia Rowland, on the following morning. The habitats were mostly agricultural fields known to accrue water after rains, good for shorebirds and waterfowl. We also birded, briefly, both mornings Harris’ Tank, a local pecan orchard, farther south than the agricultural areas, near the borders of Midland Co.

Baeza Ranch - BR; We spent all the remaining time, not listed in the three above visit, on the ranch, or driving to either Van Horn, Valentine, or Marfa, for our weekly provision runs.

I have only recorded the species of Reptiles, Birds, and Mammals encountered. I’m still learning the Butterflies, Dragonflies, an bounty of other insect life of the area. Such an interesting place. For verification of any species reported, feel free to contact me for details. If anyone would like further information on the numbers encountered, frequency of sightings, etc., please feel free to contact me at
