The kanji 集 is a phono-semantic compound (形声文字). The left side is the radical 隹 (鳥) - "small bird". The right side is 隹(木) - "tree" . The original meaning suggests birds gathering on a tree. Over time, it developed to generally mean the action of gathering or assembling in a general sense, not just for birds. The character developed from a pictogram representing birds gathering on a tree.
