Last night I went back to Valentine Well again, to try for some bats. Vikki Jackson and Mark Johnson came out too and Vikki had her bat detector. We learned a few things. One, there are apparently several bat species in the area that are not coming to the water, or at least not while I’m set up with photography. Most of what I photograph is Yuma Myotis and Pallid Bat. And that is exactly what happened again, last night. Also, it seems that the bats don’t echolocate when coming to water, the bat detector did not pick them up while they were obviously getting a drink and setting off the camera/flash. I only got a couple of good shots and both were of Pallid Bat.
Incoming Pallid Bat. I surely don’t need more photos of Pallid Bats, but it is still fun to capture images like this. Another nice capture of Pallid Bat. This was the star of the show last night! Just before Vikki and Mark left, we could hear a Western Screech-Owl, but did not see it. Shortly after they left, I heard it again and this time is was closer. I finally found it in the beam of the flashlight and could see something wriggling from its beak! I managed to get two shots before it flew off. At first I was thinking it had a small snake (small desert owls are known to put a threadsnake in their nest to control nest parasites), but as it turned out it was a large centipede. I have lots of photos of Western Screech-Owls but none are as interesting as this one! Later that night I found this one too. Judging from the markings, this is a different owl, probably the mate.
Temperatures are rising and is so is herp activity. I made a trip out to Valentine Well one night but bats weren’t very active, I only got one good shot. The weather forecast shows another warm day today and Saturday, followed by a rapid cool down.
Yesterday I saw three Western Diamondbacks. I also found two Goode’s Horned Lizards. Last night, Vikki Jackson and I checked out the pond at the golf course. There were lots of bats flying around, but the best find was breeding Great Plains Toads. One has to be there to appreciate how loud these toads are. The sound is deafening at close range. The only bat I’ve been able to photograph so far, at Valentine Well. I am not convinced that these bats are Yuma Myotis, but that seems to be the consensus at iNaturalist.It is mating season for Black-tailed Jackrabbits too, and they are often seen moving around in daytime now. Bluedicks, or Desert Hyacinth, are blooming profusely now. This plant is in the Asparagus family. Many species of wildlife and Native Americans use the root (known as a corm) for food. Desert Wishbone, a flower with a nice drop of nectar at the base of the anthers. In the Four-o’clock family, the flowers open at night and only last one day. The common name comes from appearance of the forked and white-bleached year old stems. Desert Lotus, or Desert Bird’s Foot Trefoil. The flowers are tiny, the plant forms low mats.
This evening a Falcon 9 rocket was scheduled to launch from Vandenberg SFB, shortly after sunset. The timing was perfect for a big show if the launch actually happened. And it did! Mike Venard came out to watch the show with me and we were both quite impressed. One really has to see it to appreciate the spectacular view, but I took photos, of course, and so here some of them are. They don’t really do justice to what we saw though.
Here’s liftoff, at about 7:30 PM. The planet Mercury can be seen in the center of the image, on the left side is the radar station on Child’s Mountain. Taken with a 35mm Sigma lens. The rocket is about 600 miles west heading south over the Pacific Ocean.The rocket rapidly speeds south leaving behind a wake of exhaust gases (mostly water that has frozen into ice crystals) that are lit up by the sun below the horizon. Perfect timing. The rocket has passed over Child’s Mountain and is heading south at probably around 5 miles per second. The booster can be seen falling away into the Pacific Ocean. By now, the whole western sky is filled with this. The booster is streaking away toward the Pacific Ocean. After the rocket was gone, these clouds remained for quite a while, basically man-made noctilucent clouds, very bright and colorful. I quickly changed lenses to a 135mm for this shot, a close up of the exhaust cloud. What a show! This is the third time I’ve seen this happen, but this was the best one I’ve seen. I posted some photos on Spaceweather.com and see this morning that one is featured in on the main web page, it can be seen at this LINK.
This morning I went on hike up Child’s Mountain. It has been pretty chilly the last few days and it still was this morning, until the sun finally came out. My hiking trail is the road that leads to the summit. It is gated and open only to foot traffic. Off road, the terrain is very rocky and steep. The flowers are really coming along, Brittlebush is starting to bloom profusely. About a mile up, there is a flat and there I discovered a new plant for me, growing in abundance.
The new plant, Desert Onion, Allium macropetalum, a species of wild onion that is reported to be common and widespread in the southwest. However, according to records in iNaturalist, it is rarely reported in most of the Sonoran Desert. It is not even listed in my book Sonoran Desert Wildflowers. UPDATE: After some discussion in iNaturalist, it has been decided that this plant is Sperry’s Onion, Allium perdulce var. sperry. Rather than repeat what has already been said, if interested, read the information at this LINK .The flowers on various plants range from creamy white to a light pink, as this one shows. Here is a plant with nearly white flowers. I spent a long time looking at the variability among the plants. There were literally thousands of plants, quite amazing considering I have never seen it before. I don’t think the flowering stage will last very long though. Here’s another new plant for me, Spiny Goldenweed, Xanthisma spinulosum. Like the onion, it appears to be more common in other areas of the American southwest, outside the Sonoran Desert.Northern Mockingbirds are well known for this flight display. This is the time of year when they are very actively doing this. From a high, exposed perch, the males sing and then periodically fly up a few feet and display the white feathers in the wings and tail. I’ve tried to capture this with a camera before with little success, it is very difficult to maintain focus and the action is fast. Yesterday, I finally got a few photos that are worth showing. I would have liked a little more light on the eye, but this is the best I have so far.
Last night I finally got the 500 f4 pointed to Comet 12P/Pons Brooks. This is the comet that the media has somehow come up with the name of Devil Comet, due to its odd shape earlier this year. All the hype aside, it is a bright comet right now and can be seen with binoculars low in the west after sunset. 12P/Pons Brooks is a periodic comet with an orbital period of 71 years. I thought I was going to have a hard time with it since the moon was quite bright, but it turned out to be quite easy to process.
I think if the moon hadn’t been so bright I could have got more of the tail, but I’m pretty happy with this. This is the result of 27 twenty-second exposures stacked in Deep Sky Stacker comet mode. Emory’s Rock Daisy is quite common now, rocky slopes are loaded with it. I haven’t seen much Owl Clover this spring. It is one of my favorite desert flowers, and had to photograph this one. My first Desert Spiny Lizard of the spring, out getting warmed up in the morning sun.
I made a trip to Buckeye to stock up at Walmart and on the way there, I birded. There were lots of birds at the Gillespie Dam, hundreds of egrets and herons, two species of cormorants, and lots of pelicans. Astrophotography continues to be hard, with too many clouds. But I have managed to get some done. I also made a trip down to Alamo Canyon, long overdue.
This is Abell 31, also known as Sh2-290. It is a very faint planetary nebula in the constellation Cancer. It is so faint that I cannot see it in any of my images until I stack and process. As far as planetary nebulas go, it is fairly large in view. This is what I got after 8 hours of exposure with the Nebula Booster filter and the 500f4 lens. Comet 62P/Tsuchinshan is now passing through the Virgo Galaxy Cluster, so I tried it last night. At magnitude 10.5 it isn’t very bright. The comet is over 50 million miles distance. The galaxies are on the order of 50 million light years, some are nearly 90 million light years out there. On a walk in Alamo Canyon, I found lots of Miner’s Lettuce, Claytonia perfoliata.And also Redmaids, Calandrinia ciliata.Some of the pelicans and one Snowy Egret at Gillespie Dam. Snowy Egret swallowing a fish. Abert’s Towhee at Gillespie Dam. Some of the egrets I saw. At 100mm focal length, this is all could get in one frame. Also in Alamo Canyon, I saw several Empress Leilia nectaring on Gooding’s Vervain. For me, this is unusual for two reasons. I rarely if ever have seen this species of hackberry butterfly nectar on anything and in my experience, not many butterflies nectar at this species of plant. At the parking lot in Alamo Canyon, I watched this Northern Cardinal repeatedly attack its image in a sideview mirror on another car parked there. Then it flew up onto this Saguaro to sing loudly!
It has been a while since I posted anything, so here it goes. The weather here has been just perfect, not too hot, not too cold. Unfortunately, there have been a lot of clouds cutting into my astrophotography. All the rain has started another spring bloom that could rival last years. I have to keep reminding myself that it is only early March, once the weather turns warmer, the herps, plants, insects, birds, mammals will all be more prominent. I am really looking forward to it.
This is an Acuña cactus (Echinomastus erectocentrus acunensis), an endangered cactus that only occurs in five known populations in the United States, according to my book Field Guide to Cacti and other Succulents of Arizona. I recently was shown where one of those populations is, right here in Ajo. Today I checked it out again and found one in flower. There is a dozen or more cactus in this population, though I have not made an exact count. This is Silverpuff, Uropappus lindleyi. There are a lot of these in flower now in localized areas. I liked how this photo turned out. Pelotazo (Abutilon incanum) is flowering too. A true plant of the Sonoran Desert, it requires warm winters and summer rains. It is not found in the Mojave Desert region. A late afternoon scene from last week. I was watching for a rainbow to form after some showers passed by but instead got this. The setting sun lit up the mountain known locally as Noah’s Ark in the Sikort Chuapo Mountains, east of Ajo. I had the C8 out for a few nights and did a test run on M81, Bode’s Galaxy. This came out really nice. Below M81, just above the edge of the frame, is Holmberg IX, a faint dwarf irregular galaxy and a satellite galaxy of M81. A little above on the right side of M81 is a double star that is clearly seen split. It was 100 years ago, in 1924, when Edwin Hubble proved that many of the nebulas seen in space were much further away than previously thought, millions of light years away, and that these were actually other galaxies like our own Milky Way Galaxy. M81, once known as Bode’s Nebula, is one of the billions of galaxies we now know exist.
