TUBAC NATURE CENTER JOURNAL - CHANGING TUBAC
We took possession of our house in Tubac in the Fall, 2006. There were only two other houses in this section of Barrio de Tubac, things were a little wilder then. Our first night we were convinced that there was a noisy party going on down the street. At times the party seemed to be accompanied by an obnoxious smell, like a skunk but not a skunk. We soon learned that our revelers were a group of javelinas, probably enjoying an evening meal. On subsequent nights we heard Great Horned Owls calling regularly, nearby. Coyotes had prolonged yipping sessions as I assume they celebrated a successful hunt. There were many other night sounds that we could identify, and some we could not.
In the daytime Greater Roadrunners cruised our yard for lizards, or other tasty morsels. Lately, we rarely see them. Similar to Green Valley, Gambel’s Quail were everywhere walking through the unbuilt lots. The quail have long since disappeared. Say’s Phoebes were regular insect hunters on our porches, often perching on the furniture. They are mostly gone too. Across the unwalled portion of our property and the adjoining common area we occasionally saw bobcats, coyotes, and foxes saunter through casually hunting. The common area is now neatened of its low vegetation and the many rabbits that called the area home have all but disappeared. Not surprisingly the bobcats, coyotes, and foxes rarely visit anymore. Sad!
But the wildlife has not abandoned us. The Bewick’s Wrens still methodically search through our outdoor furniture for hidden insects. Often I sit about 3 feet from the screen across the open sliding glass door in my den and the wrens crawl up the screen searching for choice morsels. Most years we have at least two Broad-billed Hummingbirds nesting in our shrubs. Eurasian-collared Doves are nesting in a tree on the north side of the house. The Northern Cardinals and Black-throated Sparrows are constantly about, though I haven’t located their nests. The Brown-crested Flycatcher will soon land in the tree outside our bedroom window and screech his good morning “song”. A rooster’s morning greeting sounds sublime compared to this critter. The javelinas still come, especially in the Spring when the live oak trees drop their tiny acorns. This time of year tanagers, orioles, and grosbeaks stop by to check the place out, and we get to enjoy them without venturing outside. We have learned in the last few years that the hawk migration up the river does not end when the calendar turns to April. While the Common Black Hawks and many of its cousins have already settled into the nesting process farther north, the Swainson’s and Broad-wing Hawks are filling the skies above Tubac.
Did I mention the sunshine? It is an almost constant companion and can raise any spirits out of morning doldrums. Right now a little, or maybe a lot, more rain would be welcomed, but there is something about the sunshine that makes it hard to be miserable. And I don’t think that is going to change!

American Kestrel (Falco sparverius)
American Kestrel
(Falco sparverius)
The brightly colored American Kestrel is North America’s smallest falcon, measuring just 8 to 10 inches in length. They feed primarily on insects, small rodents and sometimes birds. This fierce hunter adapts well to human-influenced habitats and urban settings, but the species’ population is declining in many regions of the United States, including Arizona. Tucson Bird Count data show a sharp reduction in numbers locally since 2010. Kestrels suffer from habitat loss and a lack of available nest cavities. Fortunately, this species readily accepts human-crafted nestboxes.
Nestbox programs are currently supporting the American Kestrel around the country. Watch for these birds perching on utility wires or hovering in the sky as they search for prey below. You may hear them calling: klee-klee-klee.
HABITAT Kestrels prefer semi-open country of all kinds,
especially with available hunting perches providing views of surrounding land. In the Sonoran Desert kestrels frequently nest in flicker holes in saguaros. Kestrels also nest in urban and suburban palm trees, underneath untrimmed fronds.
BOX MOUNTING Boxes should be placed between10
and 20 feet high with a northern or eastern orientation. They can
be affixed to houses, trees or poles. Boxes should not be placed among dense trees or shrubs, an open flight path to the entrance of the box is a must.
NESTING FACTS Kestrel pairs in Arizona deserts begin
courtship in late winter. The male often performs impressive feats of aerial display. As the time for egg-laying draws near, the male provides more and more of the female’s daily food. Kestrels lay eggs as early as March, but the peak of the breeding season is in April and May. The birds use no nesting material, laying eggs on debris found naturally in cavities. For nestboxes, we recommend providing wood shavings to cushion the eggs. Kestrels may return to reuse the same nests, year after year. During the winter, kestrels sometimes roost in nestboxes and cavities.

Sign up: Support the Santa Cruz River Urban Wildlife Refuge
https://santacruzriver.org/letter-of-support/
Together, we represent thousands of Pima and Santa Cruz County residents who want to see the river corridor protected in perpetuity. The Santa Cruz River Refuge coalition recognizes that the Santa Cruz River has been a storied spiritual and cultural place for the Tohono O’odham and their distinct ancestors, and Pascua Yaqui people from time immemorial. We recognize that the people of the San Xavier District, in particular, have ancestral ties to the flowing Santa Cruz River and the lands around it. The original homeland of the O’odham and their ancestors, including the Hohokam and Early Agricultural People, is located on the river, which they collectively have stewarded for millennia. They continue to access these lands for ongoing cultural and religious practices.
The ecologically and culturally rich Santa Cruz River flows through the heart of Tucson, a fast-growing city of over 1 million people in the greater metropolitan area. After generations of colonization and groundwater overuse, the surface flow stopped running in some areas, with flows all but drying up except during heavy seasonal rains. In 2012, Pima County approved funding to vastly improve the quality of wastewater effluent that was being released into the Santa Cruz River. By upgrading the wastewater treatment facilities—which currently release highly treated wastewater into the Santa Cruz—local leaders, alongside restoration volunteers, created over 25 miles of vibrant habitat that has been foundational to the recovery of native vegetation, wildlife, insects, and migratory bird species.
The Santa Cruz corridor offers abundant recreation opportunities, including birdwatching at Sweetwater Wetlands and cycling and walking along the beloved 137-mile Chuck Huckelberry Loop, a popular paved recreation trail with dozens of access points that runs alongside the Santa Cruz and its major tributaries.
Our vision for an urban national wildlife refuge imagines an archipelago of protected properties along the Santa Cruz River that would offer permanent wildlife habitat and outdoor access. The Tucson land would anchor this “string of pearls,” offering shade, river access, and outdoor education for the neighboring communities. The Santa Cruz River Urban National Wildlife Refuge draws inspiration and lessons from current exemplary restoration work happening along the corridor, including the San Xavier District’s Wa:k Hikdan project.

Wildlife Emergency
Tucson Wildlife Center
If you have a wildlife emergency, please call our 24/7 helpline at (520) 290-9453. We are available to answer calls and to offer advice. We will travel after hours for emergency wildlife situations if we are available and if the situation warrants. Our hours of admission/intake are from 8am to 5pm daily.
Hello... I'm a bat...
I don't suck blood and I don't want to get stuck in your hair.
If I accidentally walk into your house,
please don't hit me with sticks or brooms, it really hurts and I'm very scared.
It was an accident, I didn't want to scare you. If I land, I may not be able to get up and I need your help. Just use a towel to get me out and I'll fly right away, I promise. I eat mosquitoes and many other insects. Our houses are being demolished for other buildings and we only have a few places to shelter. so if I fly into your house, turn off the lights, leave the outside light on and leave the door open, I'll be out in a heartbeat.
Be a human, I want to live too..
Local Backyard wildlife by Glenn Walen
A mother and her three nearly full grown kittens paid us a visit for a drink from the birdbath. This wasn't the first time, since a few mornings recently I found the birdbath bowl tipped onto the ground. I thought it must have been deer but now I know who the real culprit is. We live in Rio Rico on the western slope of the San Cayetano mountains overlooking the Santa Cruz river. These beautiful bobcats are just one example of the abundant and varied wildlife we enjoy on a daily basis. photo by BRUCE TILDEN

HELP THE BIRDS SURVIVE THE HEAT
HELP !!! ALL OUR BIRDS ARE THIRSTY and need water to cool off !
Leave out CLEAN water for birds in a bird bath or another type of clean ceramic dish. Remember that water can get moldy which can kill the birds, hummingbird sugar water too, so change it every other day.

How to Avoid a Lion Encounter
Painting by David Simons
Do not run. Running into a large predator in the wilderness will instantly trigger your fight-or-flight instincts. Follow the former; do not ever turn and run from a cougar. This is certain to trigger the cat’s predator response — they almost universally take prey by chasing and attacking from behind.
Look big. Make yourself look bigger to the cat. Open your jacket, raise your arms and spread your legs, and face the lion at all times. If you have trek poles or any objects handy, wave them around — and be prepared to use them to defend yourself.
Make noise. Speak loudly, and make as much noise as possible. There are plenty of anecdotes of people scaring away mountain lions with loud music (Metallica, in particular) played from a speaker or smartphone.
Maintain eye contact. You may have been told that staring down an animal is considered a challenge that could invite an attack — especially with dogs — but, in this case, maintaining eye contact with the lion is a best practice.
Stand your ground. If the lion challenges you by approaching from a distance, stand your ground. To the lion, only prey animals retreat. Lions don’t recognize a standing human as a typical prey animal. Standing your ground reinforces this fact.
- Throw objects and retreat. But if the distance between you and a curious mountain lion closes to an uncomfortable degree, it’s time to act in self-defense: Throw rocks, sticks, and other nearby objects in the cat’s direction, and slowly walk backward to put space between you and the cat.
If a Mountain Lion Attacks
Do everything to fight back. Adult male lions weigh 135 to 175 pounds, while females weigh between 90 and 105 pounds. These are powerful creatures with sharp claws and strong bites, but they aren’t insurmountable — and, if you’re attacked, there’s nothing better to do than to fight back. Mountain lions usually attack the head and neck; do your best to protect these areas by remaining upright and facing the cat during the attack. Use any weapon available to you. A sharp crack to the skull with a rock, or a blow to the body with a pocket knife or any other sharp implement, could be enough to end the attack.
Immediately Report All Sightings
If you see a mountain lion near any area frequented by people, immediately contact your local authorities. If you’re near a state park or forest, contact park officials or your state’s Department of Wildlife. If no contact information for rangers or DNR services are available, or if you see a lion near an urban area, contact your local sheriff’s office or police department — they’ll either respond directly, or contact the appropriate wildlife service.

HOW CAN I HELP BIRDS?
I was recently asked by someone "how can I help the birds?" While it is sometimes easy to feel helpless, there is so much you can do!! Here are some tips:
- Vote for and support people and organizations who will fight climate change. Climate change is the number one existential threat for not just birds, but all living things, including us.
- Support bird conservation organizations at the local, state, and national levels.
- Keep cats indoors and learn how to protect birds from window strikes.
- Educate yourself about birds, as well as the healing and wellness power of birds and nature so you can educate others.
- Participate in HawkWatch, Citizen Science, such as Project FeederWatch and eBird so scientists can learn more about how birds are doing and what they need.
- Create a bird sanctuary in your own yard with native plantings to help resident, migrating, wintering, and breeding bird species.
- Feed the birds and learn best bird feeding practices to successfully attract the most birds and keep them safe.
- Mentor someone and help them learn about birds, including kids!!
Chasing Monsoon Waterfalls
Santa Cruz Valley National Heritage Org.
In Southern Arizona, monsoon rains usually come in early July, although the official monsoon season kicks off on June 15 and runs through September 30, with many factors throughout the spring and early summer influencing its exact start. The word monsoon is derived from the Arabic word mausim, which means season. Monsoon thunderstorm activity accounts for two-thirds to three-fourths of the annual precipitation in Southern Arizona, where short-lived, intense monsoon thunderstorms can cause flash flooding in areas with steep terrain, low-lying roads, or normally dry washes. Lightning, hail, dust storms, and strong winds often occur during the monsoon season. Furthermore, it is incorrect to call a single thunderstorm a “monsoon,” rather it is a large-scale weather pattern that causes these thunderstorms.
The dew point can help predict when the monsoon is likely to start. When the dew point hits 55 degrees on three consecutive days, the chance of monsoon rain is high.
Places to see waterfalls after a good rain:
- Bridal Wreath Falls in the Rincon Mountains
- Maiden Falls in the Santa Catalina Mountains
- Seven Falls in the Santa Catalina Mountains
- Tanque Verde Falls in the Rincon Mountains
- Romero Falls in the Santa Catalina Mountains
Safety tips:
- Check the weather forecast before setting out.
- Hike in the morning instead of the afternoon, when flooding is more likely to occur.
- If you hear a flash flood, get to higher ground as quickly as possible.
- Keep in mind that stream beds, narrow canyons, and washes can flood quickly.
- If you see an area with flash flood warning signs posted, proceed with caution.
- Remember, it can be raining upstream even if you can't see it, which can cause flooding downstream.
