Take yourself out to Sabino Creek - and see if you can catch some waves!

Water normally sticks to itself. This allows tiny critters like Water Striders to 'walk' on water. As tiny particles - dissolved organic carbon, to be exact - get washed into the creek after it rains and get further churned up as they flow downstream, they reduce the stickiness of water to itself and allow air to be trapped as bubbles. The bubbles then congregate on the surface where the flow isn't as swift. You can sometimes see inches of thick foam around rocks and near the 'shore.'See you in the canyon!
The source for this organic carbon is - you guessed it - anything that was once living. Algae, plants, animals - we're all carbon-based life forms. Bottom line: harmless and 'natural' in Sabino Creek.
Yes, detergents, soaps, fertilizers, and other substances can cause foam; and that's not usually optimal. I'm reasonably certain that good ol' dissolved organic carbon is the source for the soapy foam on Sabino Creek.
(You might wonder what 'inorganic carbon' is. Best example: diamonds. Made of carbon, but not alive. If you find any when you're panning, be sure to let me know.)

These two woodpeckers like to hang out at my hummingbird feeder in the Sabino Canyon Volunteer RV Compound. I realize there are differing opinions on bird feeders, but I have sure learned a lot about bird behavior having this show out my window. I never realized how much hummingbirds and even the verdins protect their food source territories. It’s interesting to see which other hummingbirds the owner of my feeder – an Anna’s hummingbird - let’s in. And how much he chatters when the verdins or Gila woodpeckers take over.

The seeds and cotyledons are dangerously poisonous and contain the highly toxic glycoside carboxyatractyloside.
It was unexpectedly dark today, so when life throws you lemons, make lemonade. Dark scene, long exposure, and high F-number results in the “fluffy” water.

I knew I had seen those eggs pictured somewhere and sure enough I found them in the Kaufman Field Guide to Insects of NA (Eric Eaton/Kenn Kaufman). They are the eggs of the one of the angle-winded katydids, most probably the Greater Angle-wing (Microcentrum rhombifolium). Anne’s blog of December 23 had a couple of Marty’s photos of the adult we found just above the dam (not too far from these eggs).

Linda and I were sitting on a rock off trail about 2 miles up the phone line trail a few weeks after the Aspen Fire (2003). Suddenly a grey fox went past us at close range. We got up to try to see it again and we saw what we think was a second fox a little further off trail. The hair on "both" animals seemed singed and we speculated that when the fire spread to the lower elevations they had been caught up in it and were fleeing the area. Although the trail was fairly quiet, it was mid-morning and it seemed extremely surprising that they would be heading south on the Phoneline trail.
Phainopepla is based on two Greek words: phainos (shining) and peplos (robe). Our Webster's Third International Dictionary, p. 1692 defines it as "as monotype genus of passerine birds of Mexico and the southwestern U.S. of which the male is uniform glossy blue-black with a white spot on each primary." My classical Greek dictionary confirms the two root words.
The pyrrho part is 'red'. The loxia refers to a genus of crossbill. Pyrrhuloxia refers to a genus of finches related to cardinals. Both roots have Greek origins but also appear in Latin. The best I can do.Thanks, Gerry!

I am releasing the third of my Arizona Arthropod Posters, True Bugs of Arizona. It presents even more diversity than the two others. I invested a lot of time in this one because there aren't really many good books available about True Bugs, but they are really an amazing group.
On the poster, 28 families (29 if you count Phymatidae) are represented by 73 identified species. A black and white template and the species list organized in taxonomic groupings comes with the poster. The posters are again 18 in x 24 in and cost $20 plus shipping.

The odd name "Pyrrhuloxia," formerly part of this bird's scientific name, combines the Latin term for the Bullfinch with a Greek reference to the bird's bill shape.

There are a number of Lac Scale insects species that might be found within the Sonoran Desert. Superficially they all look very similar - like glistening blobs of hardened shellac arranged along twigs of woody shrubs. Each species is quite specific as to the host tree or shrub used. Tachardiella fulgens is to be found on stems of the woody shrub Coursetia (Coursetia glandulosa). Not every shrub examined will have these scale insects present. Indeed, it may require searching dozens or hundreds of these plants before one of the conspicuous colonies is spotted. The hard material surrounding these bugs is a byproduct of the sugary sap that bugs take up from the plant's stems through their piercing-sucking mouthparts. It protects them from the elements and from some predators.More on shellac here.
The hard coating around lac insects has been used by people for millenia as a sealant and as a natural adhesive. Some species of lac scales have brightly colored pigment in the lac that has been used for dying fabrics.
