The (buck)eyes have it!

You can see how this pattern enhances survival! This Buckeye Butterfly was eyed near the dam.
Yesterday's bush is a creosote bush; and a good time for me to clarify something I said on a recent nature walk: the creosote used on dirt roads (for example) does not come from the creosote bush. (Thanks, Carol, for correcting me on this.)
The gall is most likely caused by a midge (according to this site): 

The Creosote Gall is formed by a Midge that is in the order Diptera and is classified with the flies.  The Creosote Gall is a deformation of the plant with the leaves and stems stunted to form the Gall.

Deck the halls with galls

Two quizzes in a row is a bit galling, I realize. What's this shrub? Bonus for a reasonable 'guess' about how the gall was formed. Answers in tomorrow's post.
Leaves from yesterday's post are (top photo) Arizona Sycamore (Platanus wrightii) and Arizona (Black) Walnut (Juglans major).

Bonus book recommendation (for that bad pun above). My cousin-in-law recently gave me a book with the provocative title Wicked Plants: The weed that killed Lincoln's mother and other botanical atrocities by Amy Stewart. Who knew there were so many plants that are toxic, poisonous, and downright deadly?! I'm enjoying it immensely. (Some say I'm enjoying it a bit too much.) If you have even a passing interest in plants, get this book. The etchings (by Briony Morrow-Cribbs) are lovely, and many of our desert plants make an appearance, too.

It's time for another quiz! Hooray. Both are Arizona trees. Answer in tomorrow's post.

Canyon Curiosity 4

This very permanent trail marker is not on (or very near) the Esperero Trail. You'll see it, though, if you go on one of Bruce's Gneiss Walks. Thursdays, 8.30-11.30am. Meet in front of the visitor center.

Merlin's beard! He's a Merlin!

Ned's favorite bird. Now you know :-)

You'll want to click on this one...

...and this one. 

Wow! Aren't these amazing?! This small falcon is a winter visitor in Sabino Canyon; a 'snow bird', if you will. But you can call this adult male 'Merlin'.

The Queen's fruit

This was a find at BioBlitz species inventories led by Jean and Mark and by Fred at Saguaro National Park East. There are Queens of the Night  (aka Night-blooming Cereus Peniocereus greggii) in Sabino Canyon, but it's a real treat to see a fruit.

Jean and Mark were visited by these Western Bluebirds (of Happiness) on the Bear Canyon Trail.
