Christophers, LTD & Astronomics, depending on whether you're into birding or astronomy. Large inventory, decent prices - particularly on sale and overstock items.

Bird Pictures by Bill Schmoker -- some very nice bird photography. Check out his blog, also.

Bird Song Guide -- I'm not personally familiar with this collection of bird songs, but if you are, let me know your thoughts on it. The number of birds is limited, but it would be good for a beginning bird watcher and the price seems OK.

For an extremely large collection of bird songs (tropical) check out Xeno-Canto.

For something more familiar to most of us, take a look at the Bird Watchers' Digest web site. Lots of information, particularly for beginners.
