Not all animals that are rescued are returned to the wild. That's one of the great things about Zoos. Now only do they let us see animals that we would never see otherwise, thereby gaining an appreciation for magnificent creatures that should be saved, but they allow for injured animals to live out their lives in comfort, again allowing the masses to see magnificent creatures.

Zoos and Aquariums also breed animals that are then released into the wild. In 1987 there were 22 California Condors left in the wild. Courtesy of a program introduced by the San Diego Zoo, and now partnered with the Los Angeles Zoo and, I think, the Phoenix Zoo, there are, as of May 2012, 405 living condors, 226 in the wild and 179 in captivity.

To want a species to go extinct for any reason is, in my opinion, simply cruel.

My avatar is of a golden eagle rescued and rehabilitated by the San Diego Zoo. It's injuries prevent it from being released back into the wild.

The bald eagle in the following picture also was rescued as a juvenile and rehabilitated by the San Diego Zoo. It's injuries prevent it from flying so it cannot be released back into the wild. Ergo it gets to live out its life as a resident of the beautiful San Diego Zoo for all to admire and adore (and take pictures of), gaining an admiration of them which, hopefully, leads to many more people helping to protect all wild creatures.

SeaWorld also does a lot of 3R (rescue, rehabilitation, and research). They have staff and veterinarians on call 24/7. Hundreds of times each year they go out to rescue injured or sick whales, dolphins, otters, and seabirds.

Thanks everyone. I read up on the D7000 and it seems to be quite impressive. As with the D200 the D300s is probably more camera , with respect to build durability, than I probabyl need. I don't consider myself a heavy abuse type of user, Though I did like all of the weather sealing that the D200 had.

I did some checking on price and it seems as though the going rate a=is as you all said, about $1100 for the body only.
I did see some low ball prices, as low as the mid $500 range.
Does anyone know what the gimmic behind those low ball prices are.
I have always made my purchases from B & H Photo or J & R and was very happy, but the thought of going from $1,100 dpwn to say $600 has peeked my interest.

Rather than using a "can" for your mount, I have used and still do the body cap and for the lens I use a variety of 8 and 16mm movie camera lenses reverse mounted to the body cap. They already have an adjustable aperature ring. The lenses I have have filter screw rings on them and when you mount then to the cap all you need to do is mount and screw the ring to the cap with no messy glue/tape,etc. I have also used a 110 film Kodak carousel slide projector zoom lens for a "zoom macro lens" This configuration works on both film/digital bodies.
