There is an established market for bioculars with built in digital cameras; but, our cursory evaluation suggests these are destined for the closet-fill corners of gadget history. The only thing worse than wasted "stuff" is stuff that's fluff, and therefore wasted.
The better way is to adapt a decent digital camera, which you may already have and spent a lot of time learning to link to your computer, to fit with a decent spotting scope. For a good sampling of spotting scopes, try this link to Cabella's catalog, which is huge. If you buy something from them, by the way, you'll get amazing catalogs for years.
The "adapting" part is where things might bet get tricky without some help. The LE-Adaptor company offers the cleanest solutions we've seen to bridge a digital camera to a scope. TreeHugger suggests you keep the production of more stuff down by going for a used spotting scope that fits a known LE-Adaptor or similar product. A quick look on Ebay verified that there are plenty of used scopes available.
If you're afraid of becoming a Crowned Geek of Digiscopy (a species that Audubon and Agassiz both missed), by indicating your interest in this, it may of some relief to know that you are in good company. A 2001 report released by the Department of Interior's U.S. Fish and Wildlife Service found that "66 million Americans spent more than $38 billion in 2001 observing, feeding, or photographing wildlife". The report, called the 2001 National and State Economic Impacts of Wildlife Watching Addendum relied on data collected in the Service's 2001 National Survey of Fishing, Hunting, and Wildlife-Associated Recreation.
It's fine to admit you like birds. Photographing them won't detract from your status as a full-fledged TreeHugger. We promise.
