Feather

Feather 6722

Also on my July 9th visit to the southern part of Great Hills Park I found and photographed this feather. If anyone knows what kind of bird it’s from, please speak up. Although the photograph above might make it seem that pastel shades of brown and blue are the only colors in the feather, the enlargement that you can get to by clicking the thumbnail below shows that there are flecks of many other colors as well. I suspect those colors aren’t intrinsically there but are created by iridescence or other optical phenomena, as they are on butterflies’ wings, but I don’t know for sure.

By the way, even if it looks like I used flash to take this picture, I didn’t.

UPDATE: I sent out a request to people in the know about birds to see if any of them could identify this feather. I got the following detailed (and initially humorous) reply from Chuck Sexton:

That’s a bit of a tough photo quiz.  I’m not used to looking at feathers this close up.  Please take the feather, walk 50 yards away, and I’ll stare at it through binocs!  ;-)

The shape of the feather suggests it is a body contour feather like a breast or belly feather.  The narrow brown or reddish barring suggests one of two species, both of which nest in Great Hills park:  Red-shouldered Hawk and Cooper’s Hawk. These birds both have rufous-barred underparts.

I’m not sure I’ve heard Cooper’s in the park this summer although they’ve nested upstream near my yard about 2 out of 3 years in the past.  Red-shouldered on the other hand has been a regular noisy resident and that’s what I’d bet on.

Not a tuft of hair

Daddy Longlegs Clump Under Limestone Overhang 6801

On July 9th I checked out a large limestone overhang in the little-frequented southern part of Great Hills Park. On the underside of the overhang I noticed what appeared to be a large tuft of hair, though I knew it couldn’t be that. It turned out to be a bunch of daddy longlegs that had clustered in the way they seem fond of doing. Another name for daddy longlegs is harvestmen but another name for them isn’t spiders, because these creatures are in a different group of animals that you can read about in an article from Clemson University.

It’s rare that I aim my camera straight up, but this was one of those times. I do occasionally use flash, and I had to for this photograph because it’s always pretty dark under that limestone overhang. The wall of the overhang, by the way, was (and still is) the site of mud dauber wasp tubes that appeared in these pages two summers ago.

Beaucoup bouquet bokeh

Sinuous Firewheel Flower Stalk by Flower Head 4262

English doesn’t have a lot of words that originated in Japanese*, but as far as I’ve been able to tell, the recent addition bokeh appears to be one. The word means literally ‘blur’ or haze’ in Japanese, and photographers worldwide have begun using the term to designate the out-of-focus parts of a picture. While the firewheel (Gaillardia pulchella) flower head in the background of today’s photograph isn’t really a bouquet, it certainly appears as a colorful bokeh. Add the sharply rendered details of the sinuous firewheel flower stem that runs diagonally across the foreground, and you’ve got a welcome contrast. For more on bokeh, you can check out this article.

I recorded this abstract view in Great Hills Park on June 16th. That was two months ago, and although the great colonies of firewheels have gone to seed and dried out, I’m still seeing an occasional lone flower head of this species asserting itself as I wander about Austin.

* Most of the words that have entered English from Japanese were originally Chinese, including tofu, geisha, soy, tycoon, honcho, and bonsai.

On July 7th I went walking along Bull Creek and found this fern. Backlighting and translucence were there too.

One good turn deserves another

Mustang Grape Tendril by Pond 0845

What the adage says about turns could be said of tendrils too. Here from July 30th with the Riata Trace Pond in the background is another and more abstract view showing the kind of tendril you saw last time, that of a mustang grape vine, Vitis mustangensis. In yesterday’s photograph there was a stalk for the vine to wind around, but even without anything to grab on to here, the tendril couldn’t keep itself from looping. That’s what a tendril of this kind knows to do, and that’s what this one did. You can see that the branch of the tendril going off to the upper left is beginning to curl at its tip in a similar way.

Mallophora fautrix Robber Fly on Stalk 0804

Beards: one on the photographer, another on this robber fly, and not all that different in color. The robber fly (also known as a bee killer) is Mallophora fautrix, and the tendril is that of a mustang grape vine, Vitis mustangensis.

This picture is from the Riata Trace Pond in northwest Austin on July 30.

Yellow Lotus Seed Capsule 6969

Yesterday’s post showed a yellow lotus flower, Nelumbo lutea. Now you get to see what the plant’s seed capsule looks like. As before, this photograph is from July 10th at the Lady Bird Johnson Wildflower Center.
