Supermoon au naturel, and not

Here’s what the June supermoon looked like last night, rising over our neighbors’ roof:

The photo above is  an unmanipulated image (except for a little tweaking of contrast): I shot the moon, the tree, and the roofline as seen, with a tight zoom and digital cropping.

Now for a little fun. Remember? new camera, still learning. I was able to get good shots of a saguaro at dusk and good shots of the moon — just not both in the same frame! The moon indeed came up under this venerable saguaro’s arms from our viewpoint, but “on film” without quite so much lunar precision (at least in camera: it looked a lot like this to the naked eye). Photo-editing software to the rescue! I edited two of the night’s high-detail photos — one of the moon and one of the giant cactus — into one.  Please enjoy the image below, but think of this one as art and not astronomy:

The next “supermoon” is on August 10, 2014; maybe by then I’ll be able to get the shot without benefit of photoshop. In fact, mulling this over, I think I figured out one way to capture both the dim spiny green of the cactus, and the bright silver moon: this may be a job for High Dynamic Range!… And, there’s always tonight, as long as there aren’t any clouds.

If Sikorsky made insects

Robo-fly or Robber fly? This handsome ærial predator was basking on the parsley in the garden this morning.  I’m armed with a new camera, just getting acquainted, and marauding for likely subjects.  Still learning — in fact, I hadn’t figured out how to shoot in Macro mode at this point, but the standard shooting mode digitally cropped for a zoom did a fair job.  It’s hard to see, but I believe this bird has lunch in its mouthparts; I spy extra wings under the crook of that front leg. And check out the grappling-hook feet!

Larval, dude.

It’s squishy and voluminous, bulbous-headed and bulgy. Plus, it engulfed every single leaf of a poor little potted chile, covering the soil below with drifts of black frass, but… it’s REALLY GREEN, and I think it’s pretty spectacular, in its way. It’s a hornworm — I’m not sure which — which makes it the larva of one of the Sphinx moths. Two days after I took this photo (do click to enlarge, I loaded a file as monstrously huge as this caterpillar is), it disappeared: it must have plopped to the ground below the plant to bury itself a few inches down in the soil to pupate. Then it will emerge as a moth. I’m trying to imagine what it looks like when a full-grown sphinx moth — a creature of the night air — emerges from dirt. Imagine!

Check the sparse, sparkly polyester-looking hairs on its back, the bristles on the “feet” of its fleshy, blunt prolegs. And the golden “portholes”. What a machine! We’re watering the now leafless chile plant, hoping the frass dissolves and the plant can re-process the nutrients from its own devoured, caterpillar-bypassed leaves to grow more. (Photo A.Shock)

Life in the day of a Fritillary

There’s a certain Passionflower vine that grows in an unlikely crack in our pool deck.

passiflora

Sonoran desert Passion flower, Passiflora foetida, a rambunctious native vine with a weird (but edible) fruit.

It’s the most enduring of all of the tough volunteer passiflora vines that inhabit our yard, exposed to blazing sun each summer afternoon, and even surviving winters with killing frosts, its roots shielded from chill and drought by the aging cement deck. This plant is crammed into the same seam as two other stubborn, spiny volunteers, a Palo Verde tree and a wolfberry, which the vine uses unashamedly for support while clambering up to the sun. This chimæric tangle of species is inconveniently located — crowding an outdoor table and the barbecue grill — but it provides prime nature-watching: towhees scrabble around looking for seeds underneath, whiptail lizards flick their tongues at ants, desert cottontails crouch in its shade, and cactus wrens glean its stems and leaves for insects.

All of the following photos of the Gulf Fritillary’s (Agraulis vanillæ) life cycle were taken on this scrubby Passion flower vine clump in our Phoenix-area back yard. (All photos A.Shock — be sure to CLICK TO ENLARGE, especially the last portrait!)

redspiny

A spiky red larva hatches from the egg and begins to eat and grow. The bright warning colors and spines advertise its body’s ability to concentrate toxins from passionflower leaves. If not discouraged by a human guardian or natural predator, fritillary larvæ can denude an entire plant in a matter of days. When it’s finished eating, the caterpillar anchors itself to its food plant, hangs head downward, forms a brown chrysalis, and pupates.

A new chrysalis looks like a dead passionflower lear. Exactly like a dead passionflower leaf.

As the chrysalis nears maturity, it becomes transparent and reveals the new butterfly’s colors. The dark sheath on the left side is the wing. 

The chrysalis splits open, and the new butterfly hangs in the shade, pumping up its wings until they're sturdy enough to fly.

The adult butterfly’s sole role is reproduction. Never having even take wing, our brand-new fritillary is still on a stem near its split chrysalis when another one lands and mates with it. Egg-laying will begin the cycle over again.

I’ve always wondered what the “peanut gallery” looks like. Now I know….

… it’s part of our roof.

Peaches and cream

The young peachy person shown below has been hanging out in our Old Scottsdale yard, eating seed-fluffs off of Creosote bushes. It’s a Rosy-faced Lovebird (Agapornis roseicollis, formerly known as the Peach-faced lovebird) with naturally-occurring variant plumage called “Lutino”. The image inset bottom left shows a bird with the standard “wild” coloration, also photo’d in our yard.

PFLB_inset1000

Rosy-faced Lovebirds have been naturalizing themselves in the greater Phoenix area since the mid-1980s, and are probably the descendants of escaped pets. For the full story, read Kurt Radamaker and Troy Corman’s excellent account on the Arizona Field Ornithologists website.

This lemony youngster flies with two “normal”-plumaged individuals, presumably its parents. Although it doesn’t show in this photo, the bird has a few reddish feathers coming in above its beak, the first indication that it will soon sport a coral forehead. Breeders offer this azureless color variant under the name “Lutino”, but the fact that this bird is a youngster suggests that it hatched ferally, and is not an escaped pet.

Update: with a bit of further research, I turned up some info on Lovebird genetics. The Lutino plumage is a sex-linked recessive gene, which means that with two visually “wild”-plumaged parents, a visibly Lutino offspring is always female — our little Lutino is a Lutina.

Orton’s ladderback — remedial photoshop strikes again

I heard a sharp “pik” in the backyard this morning, so I grabbed the long lens and went out to look for the male Black-headed Grosbeak I’d heard and briefly glimpsed at dawn from the comfort of bed (birdwatching from bed is one of the things I love about the big sliding door in our bedroom — I should keep a bed-list: Harris’s hawk, Cooper’s hawk, three species of hummers, two owls heard, Gray fox, raccoons, etc, etc. Really, it’d be a pretty good list for mattress-based observation). Unfortunately, later in the day, no Grosbeak could be found.orton'sladderback

Instead, the generator of the “pik” call was a male Ladder-backed Woodpecker (Picoides scalaris) being shown the door by a Gila Woodpecker. Because the squabble was moving swiftly west across the yard, I managed only two or three shots and none of them were great.

The subject birds were in the shade with a brightly lit background, and because of the action, low light, and distance nothing was terribly sharp. But the Ladderback had perched fetchingly on a saguaro skeleton, and I decided to try to salvage the shot.

The result is above, a manipulated photo-based digital image, “overedited” for sure but pleasing nevertheless, with a painterly quality that captures the gist of the little woodpecker and his eponymous barred back.  Not to mention his hilarious spiky red chapeau!

Below is the undistinguished original image for comparison, with the Gila Woodpecker off to the left:

The process was hit or miss, and I don’t recall each step.  But I started by cropping the shot heavily, then I ran it through a few filters (including the canned Orton filter effect) and stopped tweaking when I liked the look.
