Late-spring Rove at Tohono Chul Park

No matter what the time of year, there is always beauty at the Park. This is one of the best times, because in addition to flowers, birds are still courting and nesting. Below is a Bell’s vireo in its nest high up in a Texas ebony tree (photo courtesy of my roving buddy, Sue Feyrer). This wonderful nest is an intricately woven and decorated hanging basket. The other pictures show some of our amazing late-spring blooms.

Dove Love, Competition, and Flowers

I wish I could invite everyone who reads this to come over to my house and look at the birds and flowers in the yard. Even though some of the flowers are past peak, it’s still amazingly gorgeous.

I’ve been worried about the white-winged dove female who has nested in the carport and raised several broods the last few years. I had seen her in the nesting spot several times, but no sign of a nest. This morning I heard white-winged doves calling, and when I looked up at the pillar where she nests, I saw her and a male dove evidently just completing copulation. She was all fluffed-out and shuddery, as I’ve seen female doves after sex. Anyway, no signs yet of a nest, but I now feel they will build it soon.

Back in the bird garden, a pair of pyrrhuloxias and a pair of cardinals squabbled over the sunflower seed feeder. It was also  visited by a thrasher and a cactus wren who shoveled seeds out as fast as it could for future eating.

Mr. and Mrs. Cardinal, at the seed feeder. The bottlebrush blossoms are so thick they have pulled several stems down to the ground.

Elsewhere, in the back and front yards, everything is blooming and beautiful.

Two Amazing Flowers and a Hummingbird

I look out the back door and I can’t believe how much beauty surrounds me. This morning I was struck by the semi-wild bottlebrush tree growing behind my bird garden. Its beautiful red bristles are tipped with gold:

A Mystery, a Parapet, and an Impostor

I had a great time roving at Tohono Chul Park yesterday with my buddy Sue. As we walked the trails, Sue noticed something very odd: shredded leaves and twigs lay beneath many creosote bushes. What made this particularly strange is that not many creatures eat creosote, which contains a number of potent  and presumably bad-tasting chemicals.

Mystery (creosote) 4-1-2013 9-32-10 AM 3255x2532MYSTERY: who is attacking the creosote?

We continued our walk, and at the top of a hill we saw this:

round-tailed ground squirrel creosote 4-1-2013 9-28-16 AM 1808x1425

It was a round-tailed ground squirrel, dismantling a creosote branch. We said in unison: “Mystery solved!” We assume that he or she was using the little twigs and leaves to line a nest.

A little farther on, in a different part of the Park, we saw this beautiful example of a wolf-spider parapet.

wolf spider parapet 4-1-2013 9-35-19 AM 2520x2138Wolf-spider hole with parapet

A wolf spider creates a hole in the ground, usually alongside a trail, and builds a very nicely-constructed parapet all the way around the hole. I have heard different stories about why they do this; some say it is to give them a better vantage of approaching prey, but I have NEVER seen a wolf spider on a parapet.

Finally, in the front of the Park, we saw something I’ve never seen there before: a hummingbird moth (white-lined sphinx moth) busily sipping nectar from a field of penstemons. The below photo is courtesy of Sheri Williamson, of the Southeastern Arizona Bird Observatory (http://www.sabo.org/):

Here’s a video illustrating why these insects are sometimes mistaken for hummingbirds:

What were those rabbits doing? And other interesting tidbits from the natural world.

A couple of evenings ago I was staring through our front picture window, as I often do, watching the birds and critters, when I saw something I’d never seen before. A cottontail rabbit was lying stretched out on its stomach in a shallow depression the length of its body. It was unmoving, and though it occasionally opened its eyes, its ears were down, and I thought it must be sick or dying.

details_rabbit(Photo courtesy of azgfd)

Another rabbit crouched next to the one that was stretched out. It seemed to be licking the face of the one lying down. It licked the right side of the face, then the nose-end, then the left side. Then it circled to the back, and licked the back part of the seemingly sick rabbit. I wondered if I were witnessing some kind of bunny funeral ritual. But then, something happened—a hawk or other predator must have appeared, because the rabbit that was stretched out suddenly opened its eyes, straightened its ears, and sat up. Suddenly it, the other rabbit, and one I hadn’t seen before took off running for the neighbor’s yard.

I have since done some reading, and believe that the stretched-out rabbit may have been a female, and that she was being groomed by a male interested in sex. But who knows? If anyone reading this has witnessed this behavior and knows what it means, please let us know in the comments.

This morning I looked out at the yard just as the sun was rising, and saw a pair of javelinas crossing the yard. Though they are big and rather awkward looking, it was amazing to see how delicately they walked on their relatively tiny hooves.

Despite their appearance, by the way, javelinas are not closely related to pigs, which come from the Old World. Javelinas, which originated in South America, resemble their European cousins through convergent evolution.  

Finally, something else I had never previously seen: a friend and I went birding yesterday at a nearby artificial wetlands. The air was thick with the mating cries of red-winged blackbirds, which could be seen in every bush and tree. While trying to attract a mate, these beautiful males actually erect the red feather patches on their wings!

My first day of Spring

I have had to be away from Tohono Chul Park for nine days. In my absence, spring arrived. The flowers are flowering, and the birds are nesting. The desert tortoises have emerged from their dens.  It is beautiful and thrilling. Best of all, the first white-winged dove of the year  arrived today, though I did not get a photo.

A thrilling bird concert

Curve-billed Thrashers and Northern Mockingbirds are two of my favorite birds. They are actually closely related—both members of the bird family Mimidae. Their bodies are nearly identical, but the slightly-smaller mockingbird is grey, white, and black, while the thrasher is mostly grayish brown. Mockingbirds have yellow eyes and a short straight beak, while the thrasher’s eyes are orange and its bill  long and distinctly curved. Both birds eat insects, seeds, and berries, though the thrasher is more of a desert dweller than the mockingbird, which is often found in urban environments.

Mockingbird                                    Curve-billed thrasher (Sue Feyrer)

Both birds excel at singing. Nearly everyone has heard the beautiful, ever-changing trills of a mockingbird in the spring, but not everyone knows that thrashers can sing nearly as well. The thrasher’s ordinary call is a piercing upside-down wolf whistle (whit-WHEET!), but their song is beautiful and very melodious.

This morning at Tohono Chul Park I heard beautiful birdsong on one of the desert trails. As I approached, a mockingbird flew into a tree above me, but it was not singing. I followed its gaze to see this beautiful thrasher singing its heart out.

Cactus Wrens Courting on a Crested Saguaro

After snow, ice, severe winds, and very cold temperatures, spring started to reassert itself today in the Sonoran desert. On my rove at Tohono Chul Park this morning, I saw these beautiful early wildflowers: Arizona blue bells with a few Gooding’s verbena mixed in.

Bluebells and verbena 2-25-2013 9-04-26 AM 3556x2473It was gloriously beautiful out on the desert trails. The saguaros on this hill seemed to glow in the beautiful warm sunshine. The saguaro on the extreme right is a rare cristate saguaro. These saguaros (and some other cacti, such as barrels) have suffered a change or injury to the growing tip and no longer grow from a point. See this link for a fuller explanation, and look at the video below for a closeup of the crest.

Saguaro hill 2-25-2013 9-32-05 AM 3216x1664

I climbed the hill to take a closer look at a very vocal cactus wren that was perched on the saguaro’s crest. While I watched, another cactus wren landed next to the vocalizing bird, and both fanned their tails in what I took to be a very provocative display. I believe they were courting. Here is a brief video of their behavior, up to the point where the second wren flew off.

The Great Tucson Blizzard of 2013

It snowed here yesterday. I mean major snow, not like that I chronicled in  a recent post. Big, soft, wet flakes fell thickly through the air, starting around noon and not ending till sometime in the evening. In parts of the city, including mine, the snow accumulated, creating phantasmagorical shapes and patterns on the desert plants. Here are a few of the photos I took around my house and my neighborhood.

Desert Snow

We’ve had two wet cold fronts pass through lately, leaving rain in the valley, snow on the mountains, and misty fog everywhere. As a companion piece to my posts about blue skies and clouds, here is what it looked like at Tohono Chul Park.
