Veery With Geology


Recent weather hasn't exactly been conducive to getting out and birding and sketching. Too hot and humid. But if you get out early enough it's not horrible.

While walking along the Wissahickon Creek this week I noticed a geologic formation that is fairly common there, terribly warped rocks that look like pulled taffy. I believe that they're metamorphic, perhaps Wissahickon Schist. For more on Wissahickon Creek geology look here. Since I'd been telling some online friends about the local geology I took a couple of photos.

Not yards away I saw a Veery. I've been hearing them and Wood Thrushes all summer long at the Wissahickon but I'm not sure how much longer they'll be here. I've yet to really track their departure dates. Maybe this year. In the past we've just all of a sudden realized that they are gone and that another winter is on its way.



I recently read a book on American watercolors in the Brooklyn Museum. It was quite enjoyable and informative. At one point there was a contemporary criticism of Homer I believe, though it might have been Sargent, saying that they were very good at portraying what they saw, but nothing more. Uh, oh! Somebody wants IMAGINATION, BIG THOUGHTS, etc.

This has always struck me as bogus. Big thoughts are right in front of you, if you portray what you see. Nonetheless there is something to the ability of an artist to construct scenes based on sketches, photos, memory, etc. I've never been good at this. So this time I decided to put the Veery in the scene of the metamorphic rocks that I'd photographed. The first attempt was the watercolor immediately above.

But the veery was not in the photo. I needed to use another of a Veery I'd taken a year or two ago along with my knowledge of veeries to place him in the picture. I think it turned out better in today's charcoal drawing at the top than in yesterday's watercolor.

That's not all that surprising. I'm much more comfortable with charcoal than with watercolor. But at least I'm no longer terrified of it. And now I have two versions. I'm also a bit terrified of portraying rocks. But these rocks are something special. So it was worth the effort.

A Thanksgiving Tradition



For many years we've always taken a break from our Thanksgiving meal preparation to take a walk on Forbidden Drive at the Wissahickon Creek in Philadelphia. Sometimes it's fairly eventful and we may see a Pileated Woodpecker or two. At other times it's much quieter. Still it reminds us of much that we have to be thankful for, especially being so near to this place of natural beauty and life. It has always seemed like the perfect entertainment for a holiday like Thanksgiving.

Thursday's walk found this White-breasted Nuthatch on a limb that crossed in front of some of the Wissahickon's metamorphic rocks. I wish I could name the rock. It looks like the greenstone we often see in Shenandoah National Park but I just wasn't paying that much attention to it when I took the photo that served as the basis for this. But it sure does look metamorphic. We also saw two other Nuthatches, one Carolina Chickadee and our first fall Brown Creeper in Philadelphia, at least 50 feet high in Sycamores and other trees. This seemed surprisingly high to us. That was one of the few places that the sun was shining though so it might be that insects were active there and the Creeper knew this. He was busy scouring under the bark.

My birthday occurred recently and among my presents were a couple of waterbrushes. I started playing with them yesterday and hope to do some more life drawings of feeder birds today and tomorrow. I also used them in this first waterbrush watercolor. It's not quite a lump of coal but leaves very much to be desired. But it was a useful experiment in using the waterbrushes and shows me that they have a lot of potential, especially for field sketches. If I have any success with feeder birds and waterbrushes this weekend I may post them later. The painting also reminds me of all the improvements I need to bring to my watercolors. That is sobering but still useful. Normally I probably wouldn't post this image. But it does serve as an illustration for our Thanksgiving walk and that is worthwhile in itself.
