Endermen from what I've seen and heard can pick up most types of blocks including natural and player-placed blocks, chests, furnaces, noteblocks, mob spawners, obsidian, and bedrock. There appear to be some types that they cannot pick up, but there is not yet any final list of these.

They're incapable of moving bedrock or obsidian. Thus, if your aim is to protect your fortress from these block-relocating creatures, opt for blocks that are Enderman-proof.

For example, blocks of obsidian, iron, gold, and diamond are immovable by Endermans., even if they meet the soundness criteria.
