The Organizer, Wunderkind, and Lung Boy wish you happy Christmahanukwanzasolstica (thanks, Jasmin) and merry days in 2015!

Thank you all for your support this year; it really made a difference for my family and me. I'm very pleased to report that my husband and I are (finally) fully employed and he's back at reasonably full lung capacity. Ellen is home from Pomona College - and we are enjoying some family time. 

Your Daily Dose of Sabino Canyon will be back on 1/1/2015. Until then, enjoy the archives on the lower left. As always, at SabinoCanyon.net.

Finally, a great thought from a great man: 

“For me, I am driven by two main philosophies: know more today about the world than I knew yesterday and lessen the suffering of others. You'd be surprised how far that gets you.”
― Neil deGrasse Tyson

Looking back over this year's posts, I've concluded that this is darn good blog! Thank you all for your support this year! Very special thanks to all the fantastic photographers - without whom there would be no reason to blog! Regular contributors and Fellow SCVNers: Ned Harris, Marty Horowitz, Mark Hengesbaugh, and Fred Heath. (Note that their family names all begin with 'H'. Coincidence?) Also The Serpent Princess. Alan Kearney, Wayne Klement, and Gene Spesard. Bill Kaufman and Phil Bentley, too. And Suzi Manthorpe, Nancy Carey, and Ricki Mensching. And, of course, my very own Honey-Matt. 

Dam Kids

The Sabino Canyon Volunteer Naturalists have great programs for kids of all ages. Pictured here is a group of elementary school students in the riparian area above the dam.

Saguaro Family holiday card

Photo by Gene Spesard 12/10/2014

Saguaros (Carnegiea gigantea) of (at least) three age groups. (Click on photo for a closer look and to see the smallest set.) They didn't get trampled, eaten, or burnt by the sun because the seeds fell (or were deposited) under the mesquite that acted as a nurse tree. The mesquite is on its way out - mesquites don't live nearly as long as saguaros - but it served as nurse for at least three generations. A very nice family portrait!

Backlit Barrel Family holiday card

One of the third graders on 12/11 corrected me when I said these are Arizona Barrel Cacti; he calls them Fishhook Cacti. We're both right, fortunately. Common names for this species also include Candy Barrel and Southwestern Barrel. (Common names can be a barrel of monkeys!) We're all talking about Ferocactus wislizenii. Fero- from the Latin ferus, which means fierce. And wislizenii for Frederick Adolf Wislizenus, 19th-century German physician and amateur botanist who collected in the southwestern U.S. You can look up the meaning of botanical names at The Botanary at Dave's Garden. Fun for the whole family : -)

Luke's holiday card

Luke is our favorite leucistic or partially albino Phainopepla, back again for the 5th documented season. I think 'we' should write up his story and send it to the Cornell Lab of Ornithology, complete with photos, of course. Who wants to be the 'we'?

Mark writes:

On the morning of Dec. 9, seven Sabino Stewards (volunteers) made the steep trek up to Blackett’s Ridge to manually remove soft-feather pappusgrass, a fast-growing invasive from Africa that has made the approach to Blackett’s look like a wheat field.
Janis Findlay, Bruce Miller, Tim Ralph, Cindy Rupp, Tim Wernette, Connie Whippo and Mark Hengesbaugh worked three hours and removed at least a thousand invasive plants. When it was time to head down, a section of Blackett’s Ridge native plants had room to breathe again and the danger of wildfire was reduced.

Anne says: Wonderful work!

Game on!

Fremont Cottonwood (Populus fremontii) for the win!

Odora-rama

All butterflies are on Odora (Porophyllum gracile). Crush the leaves or the flowers of this plant and you'll notice the scent.

Oh my, they're fungi!

Probably more fungi popping up after the rain on 12/4/2014. Do not eat!

Exceptional, too

Photos by Ned Harris 11/25/2014

This Common Side-blotched lizard is actually rather uncommon. Note the whitish band that marks the regrown tail. Yes, many lizards (but not all) can drop their tail in order to escape, but doing so is really a last resort. The regrown tail will never be as long or as sturdy. And the stubby tail probably isn't as attractive to potential mates. Better than being eaten entirely, though. No chance for reproduction in that scenario!

As Ned and I were heading out on a windy day, we saw Heather with a plastic bag o' 'expired' Giant Desert Centipede. Nothing excites the highly trained naturalist more than the opportunity to examine such a find; so we oohed and aahed and arranged a photo shoot. (I volunteered my arm as a stage.) The cause of death was unclear; may have been dropped by a predator.
We (probably) wouldn't have done this with a live Giant Desert Centipede, because their bite is very painful; but not, at least as far as is documented, fatal to humans. Amphibians, reptiles, and even the very small mammal, yes.
Thanks to Heather for picking up and sharing this great critter!

Dragonfly nymphs make these cool tracks in the creek bed. On this blog in 2011 and in 2013.

I can’t believe I’ve finally seen my very first rattlesnake for the year today at Sabino. Since it is the end of November (11/26), I was giving up hope. I usually see a few every year. I can’t think of how many times someone at Sabino has told me they just saw a rattlesnake up the trail which I could not find. Today on the east side of Sabino Creek below the dam, a couple told me of a rattlesnake they had just seen a minute ago. I ran up the trail and of course never saw it.
Later, I was walking up the Creek Trail on the east side of the creek, when this lovely Black-tailed Rattlesnake slid across the trail. He crawled into a bush and dared me to come closer rattling all the time. I took several photos of him in the bush (one of which is attached), but none were particularly good (of course a rattlesnake in the bush is definitely worth two in the hand). I decided to walk a distance away to see if he might move out of the bush.
He did and I got an unobstructed shot showing his black tail clearly. He was the longest (probably 3 ½ feet long) and thickest Black-tailed Rattlesnake I've ever seen.

Another great story from Fred!

While out today [11/26/2014] in Sabino with my wife searching for butterflies (we found an amazing [for November 26] 27 species). We could not find a Reakirt’s Blue, so I started checking the Dalea pringlei which is a known host plant .(I actually raised a few caterpillars a couple of years ago to adults to confirm that they were Reakirt’s Blues.) The only butterflies I could find nectaring on the tiny flowers were Marine Blues. For fun, I decided to look for some Reakirt’s caterpillars which are quite cryptic on the host plant. I wasn’t having much luck until I noticed this odd looking ant. Knowing that blues are sometimes tended by ants, I took a second look and saw the Reakirt’s caterpillar in the attached photos. [Click photos for larger view.]

Caterpillars of some blues and hairstreaks are myrmecophilous (a $50 word meaning they have a relationship with ants). These caterpillars have a gland which produces honeydew when stroked by the ant. This is to “bribe” the ant not to attack; further the ant repels various wasps that parasitize the caterpillars. You can see a drop of honeydew on the caterpillar (directly below the jaws of the ant) in the close-up. Although this relationship is not absolutely necessary, it has been found that caterpillars have a better survival rate where they are ant tended. Unfortunately, in some places where Argentine Ants have formed colonies (near humans as in S. California), they've pushed out the ant species that collect honeydew from insects, including aphids, and some species of blues have disappeared. Luckily, Argentine Ants don’t do too well in our hot and dry desert conditions.

And the last rerun is about plants (of course)!

I started a series of plant rants in November 2012. This is the first one!

Thank you for continuing to read this blog! New posts start tomorrow. Hooray!
