I've read that they howl when they are separated from their "pack" to allow their pack members to locate them. So yes, he is howling from separation anxiety. I wouldn't crate him without anything to play with. My dog does the opposite- she's fine in her crate when I'm gone, but howls when I'm there so that I'll let her come out and play.
He also is probably really bored in there without anything to do. Kong toys are really sturdy rubber and are safe to chew on all day. You can stuff it with kibble and peanut butter/cream cheese, or whatever your dog likes, and leave it in there with your dog, its like a fun "puzzle" for them to figure out how to get the food out of the kong, it takes them awhile. They are designed to release a little food right away, to interest the dog, and then release the rest slowly to force the dog to work on it for awhile to get the food out.
