Sandbar Shark seen in Nantucket Harbor. Unfortunately just out of range to get a clear shot of it.

First three images are direct video screenshots. Last three are high contrast showing the silhouette better.

Looks way too bulky to be a dogfish or other small shark. Fin shapes and placement don't look quite right for Great White, Hammerhead or Sand Tiger. Tail isn't long enough to be a Thresher. About right for a Porbeagle but the dorsal fin looks a bit bigger. Looks closest to a Sandbar Shark to me, but interested in what others think...

Here is the latest in my long-continuing series, "Not-Quite-Ready-For-Audubon-Magazine-Cover" bird images. I have full confidence that most birders will be able to recognize the important field marks of this male Yellow Warbler, even in the first blurry image. I include a 2nd image (taken a few moments earlier) just to solidify the ID, if not my place in bird photography legend.
The habitat was willow/alder thickets along the riparian corridor of Cherry Creek in the park.

I'm happy to offer the next installment of my long-running series of "Not-Quite-Ready-For-Audubon-Cover" bird images. Among the abundant birdlife flitting back and forth along the rugged shoreline at Sue-meg State Park, I kept hearing and seeing a few Black Oystercatchers on the wing, but could never catch sight of one on the rocks. So here is my offering of documentation of the species on this date and location. You can see a big black chunky shorebird with a long narrow dark red bill...flying at about 45 miles per hour past me. The full habitat/context is included in the 2nd image; you can see the oystercatcher just above the wave foam in the right side of the image.
I couldn't get a recording of the bird's calls due to crashing wave noise, but I was alerted to the bird's presence by it's loud, high-pitched, long series of "peek!" calls.

In my continuing series of "Not Quite Audubon Cover Quality" bird images, I offer this study of a male Vermillion Flycatcher that just did not want to be photographed. For one of the more photogenic (read: photobombing) birds, he certainly had issues.
