My husband is a HUGE Robert Jordan fan (he freaked when RJ died before finishing the last WOT book).  He also enjoys Piers Anthony.  He's read most of the Xanth books and the Tarot series.

I am looking for some recommendations of other authors for him.  He really enjoys series.  He also loves humor and he is a wildlife biologist so books with an animal bent would be a plus.

And if anyone has any deals on them, all the better!  I would love to have 4-6 books for him for XMas.  He doesn't care that they aren't new. *swoon*

George R.R. Martin!

Terry Brooks - later Shannara or Landover series.

the George R R Martin Fire & Ice series is great, has 4 book out, but still waiting on book #5 (no release date yet); I loved Elizabeth Hayden's Rhapsody, Prophecy & Destiny & the characters were wonderful; didn't go on with the rest of the books yet; at times she overwrote i think; not much, just a little. The David Eddings series were some of the best works i have read. Has he read those? His earlier ones, not the later ones; the Belgariad: pawn of prophecy, queen of sorcery; magician gambit;castle of wizardry; enchanters end game; this is followed by: the Malloreon with another 5 books; these were his best books; have read later books that aren't up to par. These have it all including humor.

Thanks.  I ordered the first 4 SOT books from Goodkind.  I am not sure if he's read the Incarnations of Immortality but I will put them on my list for him, as well as the other's mentioned.

Sounds like he might like Robin Hobb's Farseer trilogy.  It is a fantasy series with a wildlife twist to it.  The main character is a guy whose magical "gift" makes him able to communicate with animals, specifically a wolf he befriends.

I also second the David Eddings recommendations.  The Belgariad and Mallorean series (in that order) are great epic fantasy series, and both have a bit of wildlife twists to them as well (the main sorcerer character shape-changes into a wolf and communicates with them, and the sorceress prefers birds, and turns herself into a white owl).

Its a bit different than either Jordan or Anthony - both of which I really enjoy - but one of my favorite series is the Chronicles of the Cheysuli by Jennifer Roberson. Its an 8 book series (or 3 omnibus editions) about a race of shapechangers whos shape is determined by what animal they bond with around puberty.

Also for some humorous books of slightly goofy and definately pun-ish humor he might like the Dragon Knight series by George R. Martin ( the main character ends up stuck in the body of a dragon)  and though they are a bit more scifi/fantasy I love the twisted humor of the Callahan's series by Spider Robinson.

If he liked Piers Anthony, then I second the DIscworld Series from Terry Pratchitt.  The original books starred Rincewind, the inept wizard, but his laters ones have focused on the city of Ankh-Morpokh and its machinations.  I would probably start with the book Mort, and then move either forward or back from there.  Be advised that in the later books, while not necessary, things seem to flow better if you have read the previous ones.

If he has a big animal bent, then Jane Lindskold's Through Wolf's Eyes series might hold an interest.  Since one of the main characters thinks of herself as a wolf, it would be interesting.  Also a nice take on intelligent animals.

Good Luck. 

Mercedes Lackey writes a lot of books about people who are close with animals. Owlsflight is the start of a trilogy about a kid who is taken in by a tribe of people who all have big cool birds that are their friends/helpers. Most of the other books she writes have a lot of animals, too.
