Black Scoter

Thanks to JoAnne Russo, who posted a report in the VTBird list,  I was finally able to see and take a photo of an adult male Black Scoter which was swimming around by himself on a small pond in Newfane, VT. It's another life bird for me and I had been looking for one all  fall after reading various reports in the VT, NH and Mass birding lists.



The water was clear enough to show his big paddle-like feet





Well, enough. It's off for the holidays!

Trying HDR photography and saying good-bye for the year to a Great Blue Heron


I have been experimenting with HDR (High Dynamic Range) imaging. It's a technique of fusing several images taken with different exposure, i.e. over-, under- and correct exposure, resulting in an image which contains a wider range of very dark and very bright areas than would ordinarily be possible. Since there is always a small delay between each exposure the images are best taken with the camera on a tripod. Handheld images, like mine,  usually result in some ghosting and are never quite sharp.

Here is my first effort, a view from our deck on the wetland next to our house. I used a demo version of Photomatix. The sky often comes out gray and has to be corrected in Photoshop. In fact most images require further editing in Photoshop:

Here is a landscape taken in late afternoon sunlight:

A mall in Keene:



The technique is derived from 3-D imaging in video games and many of the images on the net are still reminiscent of a toy-size model set-ups. One give-away of an HDR image is the appearance of a sky with unusually dramatic cloud formations. Here is a site that explains the technique and has some good examples along with  tutorials: Stuck in Customs. I am not sure how far I am going to go with this. I generally prefer more natural-looking images but it might be fun in the winter when there are not many birds around.

While walking on the railroad trail behind the shopping mall in Keene a Great Blue Heron suddenly appeared overhead. It was the same one I had been observing for much of the summer and fall, first as a juvenile and now as a grown bird. He'll soon be off going south.



Good Birding! And Happy Thanksgiving. For us it's off to Michigan again for a week to visit family..

Horned Grebe





When walking back up I saw many American Robins and Blue Jays in the bare trees lining the road and the adjacent meadow. Suddenly I was stopped short by the unmistakable squeals of a Red-tailed Hawk which seemed to come from a mixed thicket of young pines and deciduous trees off the path. Robins kept flying into the pines and out of view. The squeals kept coming and then, just as suddenly, stopped. The Robins reemerged unscathed and flew off. I never saw a hawk and I am wondering whether the cries came from a Blue Jay practicing his hawk imitation, but I'll never know.
