Just Another Fabulous Friday at the Desert Museum

I was assigned to lead the Bird Walk at the Arizona-Sonora Desert Museum today.  These walks are led every morning just as the museum opens, 7:30 AM in the summer.  As I drove into staff parking I passed a woman peering into some bushes in the parking lot, binoculars in hand, and I knew I'd be seeing her soon. Two Canadian couples, unknown to each other, showed up for the bird walk, and yes, one of the women was the one from the parking lot.  We had a laugh about my having ID'd her early on before heading off.  I always preface my bird walks by explaining that while I have a good grasp on the common and obvious birds in this part of the Sonoran Desert -- Gila Woodpeckers, Cactus Wrens, Gambel's Quail, various doves, etc. -- I am not an expert birder, but do know where to take them on the grounds for the best bird watching.  They were fine with that, and then they proceeded to give me the best birding experience ever at the Desert Museum.

We wound our way down to the Desert Garden, pausing at the Pollinator Garden for my first good look at a Green-tailed Towee.  A brilliantly red Cardinal met us at the Desert Garden entrance and then we were off to the races.  Some highlights were the Black-headed Grosbeak, the Ruby-crowned Kinglet, a Bullocks Oriole and a Hooded Oriole, and a Lazuli Bunting.  They were thrilled to spot a Costa's Hummingbird, and we were amused by a Desert Cottontail who couldn't get his fill of primroses.  A Desert Spiny lizard in full breeding colors enticed a mate to join him on the garden wall.

It worked!  She climbed up to join him on the top of the wall
As we left the Desert Garden we had an excellent view into the high elevation Life Zones area with oak and pine.  It was alive with warblers -- Yellow-rumped, Common Yellowthroat, Wilson's, Townsend's, and a life list bird for one couple, an Olive Warbler.  There was also a beautiful Western Tanager flitting from branch tip to branch tip.  Moving on to the beaver pond in the Riparian Area yielded a Townsend's Warbler and Black-throated Gray Warbler.

One of the couples was desperate to see a Gilded Flicker.  I sent them off suggesting they keep their eyes on the holes in the top three or four feet of the saguaros as the Gilded Flickers like the penthouses.  I headed off on the rest of my morning assignments which included interpreting horns and antlers at the Big Horn Sheep exhibit.  They were out and about, grazing on their morning meal, as was a wild Spiny Tailed Iguana, a lizard from much further south in the Sonoran Desert that we have a wild population of on the grounds where water and lush foliage are available.

All in all, just another fabulous day as a docent at the Arizona-Sonora Desert Museum.
