I first visited Arizona for a few days in 1989, the highlight of which was a trek to the bottom of the Grand Canyon for an overnight stay and a battle with a Ringtail that was determined to separate me from my breakfast. I returned for a few days in September 1998, twice in 2010 , and again in 2012 (see my 2012 trip report) and 2013 (see my 2013 trip report). In 2018 I returned for a batting trip focussed on Spotted Bats and was in southern Arizona in March 2021 for a few cold days.
I have split the state into three regions: north, south east and south west of Phoenix.
A night’s batting near Flagstaff in 2018 produced South-western, Arizona, Long-eared, Fringed and California Myotis, a Brazilian Freetail, along with Sliver-haired, Hoary, Pallid, Big Brown and Allen’s Big-eared Bats. We also saw Elk, Gunnison’s Prairie Dogs and Mogollon Voles.
In November 1989 I hiked to the bottom of the Grand Canyon, camped for night, and hiked back up. My legs were still hurting a month later. I saw a few Bighorn Sheep on the main trail down to the canyon floor. And during the night one or more Ringtails was determined to eat our food. We were in a backcountry campsite on the canyon floor. I hung the food from a metal pole, which the Ringtails climbed like a ladder. I greased the pole with butter, which did nothing to slow the Ringtails down. And so I left the food under a frying pan weighted down with rocks. In the morning the pan and rocks were unmoved …. but the food had gone. It was a hungry walk back to the top. I hate Ringtails.
In August 2010 I visited the North Rim and found Abert’s Squirrel (the rather spectacular white-tailed subspecies) in the campground, although it took an hour to spot one. A different subspecies is supposed to be common in suburban Flagstaff and the Flagstaff Aboretum is one place to look. There were also Uinta Chipmunks around the Canyon Rim and a herd of Bison on the drive in.
In July 2018 a night’s batting on the Kaibab Plateau caught a lot of animals, including two Spotted Bats.
We also caught Long-eared, Long-legged, Fringed and Western Small-footed Myotis, a Brazilian Freetail,and Sliver-haired, Hoary and Big Brown Bats. In the day time we saw a Fremont’s Squirrel, a Rock Squirrel, Elk, Mule Deer, Bison and Uinta Chipmunks. We also heard Western Bonneted and Big Free-tailed Bats.
Trent Binford-Walsh told me that Western Spotted Skunks are easy to see at the base of the Canyon where they hang around Phantom Ranch looking for food.
I don’t remember much about visiting here in November 1989, other than seeing an Arizona Gray Squirrel.
Vermillion Cliffs National Monument
I visited here in August 2010, September 2013 and July 2018. The mind blowing scenery alone justifies the drive to this area of northern Arizona.
The entrance road to Vermillion Cliffs (BLM/Bureau of Land Management road 1065, about 13 miles east of Jacob Lake off of Hwy 89A ) is quite near to the North Rim of the Grand Canyon and a site for Chisel-toothed Kangaroo Rats. John Fox found one along here in 2010. In 2010 I spent an hour spotlighting here with Matt Miller and although I saw one kangaroo rat I couldn’t see it well enough to be sure which species it was. There were a lot of bats feeding around the start of the road with clearly audible echo-location but apparently several species in the area fit that description.
In September 2013 there were lots of kangaroo rats along the road. I suspect most were Chisel-toothed given the habitat they were burrowing in (lots of pebbles and heavy soil – with Ord’s the only other possibility there), though as usual it was hard to get them to stay still long enough for a good look. I did see at least one well enough to be sure it was a Chisel-toothed. There was a Coyote out there too, and Elk in the forest just a bit further north along Hwy 89a.
Two nights batting in July 2018 produced Yuma and Californian Myotis, Canyon and Pallid Bats and Brazilian and Big Freetail Bats. Other mammals comprised Black-tailed Jackrabbits, American Badgers, Ords Kangaroo Rats, Canyon Mice and White-tailed Antelope Squirrels.
Woods Canyon Lake
In September 2012 Grey-collared Chipmunks were easy to see here around the edge of the campsite a mile or so from the lake. They reacted very loudly when I squeaked. This species is also at the Flagstaff Arboretum though I haven’t seen them there.
South East Arizona
I spent a couple of days in Arivaca, near Nogales on the Mexican border, to see Charles Foley and his family in March 2021. It was unusually cold (it even snowed) and small mammal activity was probably lower than usual. I saw a pale grey Botta’s Pocket Gopher in the garden of his AirBnB house (which I originally hoped was a Southern Pocket Gopher than are also in range here) and a Coyote and Mule Deer nearby.
We had permission to trap small mammals at nearby Ruby Ghost Town, a scenic place to camp, Despite the freezing overnight temperatures we caught several Western Deermice, a handful of Western White-throated Woodrats (all in the abandoned buildings) and a Brush Mouse.
Casa Grande Ruins National Monument
In April 2010 Round-tailed Ground Squirrels were common around the visitors centre. This species is also common in the Desert Botanical Gardens in Phoenix apparently.
Chiricahua National Monument,
In September 1998 we saw Mexican Fox Squirrels around the campsite, Variegated Ground Squirrels, Cliff Chipmunks and Javelina (Collared Peccary).
Continental and Madera Canyon
In September 2012 I found Antelope Jack Rabbits along the road south of Continental towards the birding sight Madera Canyon. John Fox saw 3 along here in the mid morning. I drove up and down the road late in the afternoon for an hour and a half before spotting one at dusk. An impressive rabbit. I was focusing on the desert along the first 5 miles of road out of Continental and saw a rabbit a mile along one of the dirt tracks off to the west.
The Santa Rita Lodge in Madera Canyon is in the middle of a mammalwatching hotspot. I have not stayed here but visited the area at night in March 2021 for two hours with Charles Foley and his family. We saw a Coati and a Ringtail around the hummingbird feeders (which are next to the road) and had a long look at a Hog-nosed Skunk a mile further along the road, plus Raccoons and a Grey Fox.
In September 1998 I saw the Coues’ subspecies of White-tailed Deer, Odocoileus virginianus clavium, here.
We stayed here for a night in September 1998. This lovel ecolodge had Hooded and Striped Skunks along the nature trail and Southern Long-nosed Bats feeding from the hummingbird feeders just milimetres from my face. I think I saw an Antelope Jackrabbit here too and almost trod on a rattlesnake. Coatis and Javelinas are fairly common, though I didn’t see either here.
This is one of the best areas in the USA for mammal diversity and I visited in Septembers 2012 & 13, and stayed at Cave Creek Canyon Ranch for a couple of nights each time. The ranch is a great spot for mammals and a good base to explore the area. The owner, Reed Peters, was also ready to let me throw out some Sherman traps on the property, even if I didn’t manage to catch much there.
Cave Creek is worth a mention as a sight in its own right. I did not spend a lot of time looking on the property but would have liked to have done if I had had a bit more time. But Yellow-nosed Cotton Rats were easy to see around the bird feeders and bats, presumably Mexican Long-tongued Bats, visited the hummingbird feeders after dark.
Reed said White-throated Woodrats visited his house most nights but we couldn’t catch any. Other animals that visit the feeders regularly include Rock Squirrels, Cliff Chipmunks and Striped Skunks (all of which I saw) and Hooded Skunks, which I didn’t see. Reed had seen a Western Spotted Skunk once too in the creek behind the cabins.
In 2012 a Ringtail was denning in a tree near the cabins though I didn’t make an effort to see it. A pair of Black Bears were around both mornings near the cabins and they unfortunately developed an interest in my traps. Unfortunate for some of my traps, not for the bears!
I saw a Harris’s Antelope Squirrel along the driveway and White-tailed-Deer were common. Coatis and Javelinas are often here too.
I spent most of my first evening in 2012 just over the border in New Mexico, looking for White-sided Jackrabbits.
During my second night, I found a Banner-tailed Kangaroo Rat pretty much where John Fox had seen them on Sunrise Road, which is off to the west at mile marker 412 along Rt 80 (this is 3 miles into Arizona and south of the town of Rodeo).
A set of humming bird feeders at the South West Research Station had plenty of bats visiting which were almost certainly Mexican Long-tongued Bats. Southern Long-nosed Bats are also possible here but they are very occasional and may have even migrated by September. There were lots of fresh gopher diggings on the lawn near the bird feeders.
Hog-nosed Skunks are in the area too, but much scarcer than Hooded and Striped.
Small mammal trapping in the desert can be very unproductive but I was told of dam not far from Portal where I could set traps without a permit. It was indeed a good spot. In a couple of nights I caught a Merriam’s Kangaroo Rat and a Yellow-nosed Cotton Rat.
A couple of Hispid Cotton Rats were trapped close to the water.
As was this Tawny-bellied Cotton Rat.
And I caught several Desert Pocket Mice in the desert.
Other species that have been caught here include Southern Grasshopper Mice, Banner-tailed and Ord’s Kangaroo Rats and Bailey’s Pocket Mice.
As I was leaving Portal I stopped in at Quailway Cottage to visit the bird feeders where a couple of birders reported seeing a Spotted Ground Squirrel the previous day. I wasn’t there long enough to see the squirrel but it looks like another great spot to stay. The manager, John Yerger, is a bird guide who was helpful when I asked him about the local mammals but unable to go out with me to look for them. He’d be a good guy to meet up with next time. And there will be a next time because there are still many animals I’d like to see in this biodiversity hotspot. See my 2012 trip report for more details.
I returned in September 2013 for a night, mainly for more small mammal trapping. They didn’t disappoint and I caught more Desert Pocket Mice, plus my first Bailey’s Pocket Mice out in the desert and a Brush Mouse up at Cave Creek.
Richard Webb was, coincidentally, staying at Cave Creek too and it was good to finally meet him after corresponding for eight years. We spent three hours spotlighting.
We didn’t see a great deal on the road to Paradise, but down in the desert, along State Line road, there were lots of kangaroo rats (I guess both Merriam’s and Ord’s). I tried to get a better look at a Banner-tailed Kangaroo Rat than I’d had the year before but we couldn’t find any along Sunrise Road, other than a possible one among many smaller kangaroo rats. It disappeared before we could get a good look.
The highlight of the night were a couple of rattlesnakes on the road, and a Bobcat crossing the road near the Portal store. I saw both a Javelina and a Striped Skunk crossing the same stretch of road during the day too. And there were Black-tailed Jackrabbits along route 80.) See my 2013 trip report for more details.
The long long drive from Portal to Vermillion Cliffs goes through Tucson so in September 2013 I stopped in at the Sweetwater Wetlands, a sewage treatment works, just off Interstate 10, north of the city centre, to look for Arizona Cotton Rats, which were allegedly common and often diurnal.
I didn’t arrive until 11 a.m. so it was perhaps not suprising I didn’t see any during my hour there. And the plagues of lizards here made it impractical to check out every rustling I heard. Apart from Desert Cottontails and a Rock Squirrel I got a great look at a Bobcat (the second I had seen in about 12 hours after seeing one in Portal the night before).
I returned at sunrise in July 2018 and saw a couple of Arizona Cotton Rats, Round-tailed Ground Squirrels, Desert Cottontails, Black-tailed Jackrabbits and a Raccoon.
South West Arizona
In March 2021 I spent a couple of nights in the desert 2 hours west of Phoenix with Jose Gabriel Martinez. Our focus was on small mammals, and caught Cactus Mouse and White-throated Woodrats in rocky desert north of town, plusMerriam’s and Desert Kangaroo Rats close to Bouse. We also saw a lone Javelina and Black-tailed Jackrabbits.
A ranch just west of Seligman on Route 66, has successsfully reintroduced Black-footed Ferrets . I visited the town twice in 2010. During the day Gunnison’s Prairie Dogs are common, and at night you have an excellent chance of spotlighting a ferret along the northern side of Route 66. The best area is the 10 mile stretch that starts three or four miles west of Seligman running through the Aubrey Valley, and the ferrets are most active between midnight and 6 a.m.
.I spent 6 hours looking from 9 p.m. to 3 a.m. but couldn’t find one in April 2010. A week before people had been seeing as many as 13 during a night’s spotlighting! Immensely frustrating and my lack of success may well have been because the weather had turned cold or windy. But I did see three Badgers, Mule Deer, a kangaroo rat (probably an Ord’s), lots of Desert Cottontails and a Coyote.
I returned in August 2010. This time I left nothing to chance and persuaded Jennifer Cordova and Trent Binford-Walsh from the Arizona Game and Fish Department (and the Ferret Recovery Project) to make sure I didn’t fail twice. This which was extremely good of them and Jennifer had already provided a heap of info on where to look. They vowed to stay out til we found one!
But a late night wasn’t necessary. This time I found animals within five minutes of turning on the spotlight. A group of three ferrets were at a den about 50 metres south of Route 66 near mile marker 127. It was 10 p.m., the moon was full and the temperature about 75F. The animals have bright green laser like eyeshine.
Matt Miller and I approached animals to within about 10 metres at which point they finally went underground. But – just as Trent had predicted – once we got to the bolt hole an animal would pop its head in and out to take a peek. I was too close even to focus properly. A fabulous 20 minutes of mammal watching looking at a species I once thought I would never see in the wild!
Charles Hood sent me the following update “As of July 2012, Black-footed Ferrets remain present outside of Seligman, Arizona. Two different indivudals were seen by spotlight after 2300 hours north and south of mile marker 127, on the north side of Route 66. As a courtesy, let the ferret project staff know when you’ll be looking for them, so their wardens know who is spotlighting and why.”
In 2020 I heard from Justin Brown that no ferrets were caught in 2019 and none has been seen in 2020 either (though COVID didn’t help fieldwork). The colony may have succumbed to the plague … so check with the researchers to get the latest.
