Potpourri

I've a wonderful macro flash unit that I always felt needed attention to detail to get the best out of it. Alas, I have more often simply plonked it atop the camera and hoped for the best.

This unit is known for its leaning towards red values and I think I've found my magic numbers for proper color balance. At least, I'm a lot closer than ever before.

Also needed was adjusting the dual flash heads for location and relative power in order to introduce detail and shadow.

Killdeer

Walking between overflow beds of a water pumping and filtration center, I found this Killdeer presenting in classic distressed manner indicating that its ground level nest must be nearby. As I moved between photographs, I kept my head down--the nest could have been underfoot.




Although the image quality of this little clip suffers, you can hear the distressed calls as it does its best to call attention towards its feigned wounded condition and away from its nest.

Gray Birch

Gray Birch, Old Field Birch, White Birch, Poverty Birch, Poplar Birch. Lots of names for the popular and lovely Betula populifolia that grows sparsely around the lake.


From "Native Trees of Rhode Island":

"The gray, or small white, birch, is a small tree, but makes up incumber, where it takes full possession of the ground, what it lacks in size. It will thrive upon the very poorest of ground, hence its association with poverty. A gray birch plantation makes wood rapidly during a growth of about twenty years, when it should be cut off for a new growth, which starts with great vigor from the old roots.

The characteristics of this species are so marked as to make it stand quite alone in its aspects. It has a small body, rarely over six inches in diameter, and is thickly set with short, bushy branches, finely divided at the extremities. The tree, when alive, is exceedingly tough and elastic. In ice-storms it often makes a complete curve to the ground, as it appears in sparkling jewels of light. As the ice melts away, it again becomes upright. Few scenes in nature show such enchanting beauty as a birch woods in the morning sunlight after an ice-storm.


"The leaves of this tree have prominent marks. They are upon long, slender stems, are much expanded at the base, and taper to a long, narrow point. The margins are irregularly and sharply toothed, and both sides are shining, the upper side very noticeably so. Even in a gentle breeze the leaves quiver, aspen-like, throwing oft an attractive emerald play of light. In the autumn the leaves fall early, after turning to delicate shades of yellow.

"The bark of this birch gives the name "gray"; it shades from white into this color. It is so impervious to moisture that a stick of the wood, if not split open, will decay before the sap can escape. In the woods we often see the form of a fallen tree or limb perfect, the bark sound, while the wood inside has turned to dust.

"The wood makes a good fuel, excellent for kindling, if split and properly seasoned, or dried. The young birches are in constant demand for hoops for casks, and when large enough they are much used for poles for beans and hops, these plants clinging to this wood, with the bark on, better than to any other. Thus the "thinning" of a gray birch lot yields profit, and after fifteen years' growth the wood gives a good return of fuel.

"The fact should be noted about this species that it has important uses in the economy of nature. In good ground stronger trees overtop it and crowd it out. But its seeds go everywhere, and upon the sterile sand plains, upon worn-out lands, in deserted gravel pits, by the scarred and neglected road-sides, it takes quiet possession of the ground. In such places it draws sustenance, largely through its leaves, which, in a few years, develops the trees into sources of profit and beauty. Thus they redeem poor soils, and often act as "nurses" to more valuable trees which finally spring up among them."

Flowering Quince

This flowering quince by my doorstep is in full bloom. After reviewing the past few days of photos I began to notice the way the petals attach. Here are a few different angles that hopefully show the unusual habit of these petals. Click each image for extended detail.










I thought I had discovered a new patch of fetterbush but it looks like early blueberry blossoms.

Flowering Crabapple

It's the season for my flowering crabapples. Yesterday the bees were taking advantage of the recent blossoms. In today's rain, they were few and far between.

Common Blue Violet

The Common Blue Violet, Viola sororia, grows in every part of my yard. Always has, and I never knew its species! Today I remembered to capture leaf, stem, and flower profile images. And even inadvertently included a few tiny bugs!

Click this image for a better view of the tiny bugs.



The Common Blue Violet occasionally presents in this color variation.

Arrow-leaved Violet

Arrow-leaved Violet, Viola sagittata, grows along with the two previous post species. This plant is the only violet with heart-shaped leaves. I've never really looked at violets and just now becoming familiar with growth habits--flower structure and especially those hairy stems that bend over gracefully. I suspect there are other violet species about. I'll be on the lookout.

Glechoma hederacea

This Spring I am noticing a lot of early flowers, rich in color and complexity while small in size. I found patches of Glechoma hederacea, Ground Ivy,  in the same general area as yesterday's Bittercress.



From Sylvan Spring:

"One of the prettiest, as it is one of the most plentiful, in lane and hedgebank, of our April flowers, is the Ground Ivy (Glechoma hederacea), whose procumbent stem, and habit of freely root ing at the stem joints, cause it to creep so extensively as oftentimes to cover considerable spaces of the banks on which it grows. Its pretty little, roundish, kidney-shaped leaves, with their symmetrically lobed margins, and its axillary whorls of light purplish flowers, must be familiar to very many persons who do not know the Ground Ivy by name—though this name can scarcely be called appropriate, as the plant has no relation whatever to the Ivy, which it only distantly resembles in the form of its leaves. But in its creeping habit, in its profuse growth, and in the glow—of purple, and red, and yellow, intermingled—which often overspreads its stems and leaves, there may be found sufficient likeness to the familiar evergreen trailer of the hedgebank to warrant its designation; for while speaking of the Ivy as an Evergreen, we do not forget that in autumn and winter, and often in summer when exposed to the sun, it assumes the richest hues of red, and yellow, and purple. It is on sunny hedgebanks that the hairy stems and leaves of Glechoma hederacea acquire their gayer tints; and in this habit it resembles the Ivy. There are ordinarily six, though sometimes only three, flowers in each axillary whorl; and each individual flower consists of a tubular, acutelycleft calyx—oftentimes suffused with a hue of reddish purple—and a light purple corolla, with a tube much longer than the calyx, and with its upper and expanded part lip-shaped, for this plant belongs to the labiate tribe—the upper lip two-cleft and the lower lip thrice-cleft—with spots of darker purple near the entrance to the cylindrical corolla tube."

Barbarea vulgaris

The afternoon turned dark and wind-chilled as I set out after my unknown little plant. In mind was that just yesterday as I walked towards the main entrance of work that I'd passed by dozens of my mystery plant sprouting from the lawn. Was I being taunted, I wondered.


Today I was greeted by a field full of specimens in flower! Unlike my earlier find, these has very little purple in stem and leaf. 


Once home, with images loaded and my browser pointed to the Connecticut Botanical Society, the identification was made in seconds. Barbarea vulgaris, commonly named Bittercress, Yellow Rocketcress, and on and on.


Notice the four-petaled flower that Mike advised I watch for. And, he was spot on suspecting this was a member of the Mustard family. Well done, and many thanks, Mike! And thanks go out to Gretchen as well for all her scouting work!


From The Entomologist:

"I was walking this afternoon beside the Blackwater, a small stream which flows through our valley, when I observed a common hive bee hanging, as I supposed, by the abdomen, from the blossom of a yellow cress, which is abundant there, Barbarea vulgaris. Accordingly, I picked the blossom and examined it more closely, as the position of the bee was peculiar, and I did not think it was dead. As it did not move, I at first thought it must have been detained a prisoner by some viscid fluid peculiar to the plant. I found, however, that in reality it was being tightly held by the falces of a bright yellow spider, so exactly the colour of the yellow blossom of the Barbarea vulgaris that at first (1 know something of botany) I mistook the yellow legs of a spider for the multifid stigma of the blossom."

Egg Tempera Vinca

Trying to get into the swing of things with egg tempera. The big no-no is applying another layer before the last is dry. Notice my holes on leaf tips. I was applying light washes of alternating blue and green, developing some shadowing. Just like that, whoosh! All the layers were gone!

There's a saying with egg tempera, "Make haste slowly."

Egg Play

Yesterday I stopped in at the local farm for a dozen fresh eggs. Last evening I collected all my pigments and recorded into the laptop, just so I know what I really have. (I really have a lot of pigments!)

It's been a long time since working with egg tempera. Right after this photo, the yolk got away from me, breaking the membrane. I dumped the whole mess into my jar and I have to be careful when making up my mixes. If this was going to be a serious piece, I'd have dumped the egg and started over.



Just a bit of quick play here for working back the feeling for this medium. Now it's time to pull my egg tempera books off the shelf for some good reads.


Apologies for Blogger misbehaving today, all of a sudden comment posting failed. After a bit of poking about, it seems that popup commenting was the culprit. Changing to embedded comments looks to be a proper fix.

I'm Stumped

I've spent a good deal of time thumbing through my books and googling about, all for naught. This little plant, about 6" tall, is proving a challenge. Does anyone know what we have here?
