You can use `cl-pushnew' for pushing lists as well!
As in:
(require 'cl-lib)
(defvar bird-list-all)
(defvar bird-list-1)
(defvar bird-list-2)
(setq bird-list-all '())
(setq bird-list-1 '("Western jackdaw" "European goldfinch"))
(setq bird-list-2 '("rook"))
(cl-pushnew bird-list-1 bird-list-all) ; (("Western jackdaw" "European goldfinch"))
(cl-pushnew bird-list-2 bird-list-all) ; (("rook") ("Western jackdaw" "European goldfinch"))
Birds and Elisp! That, I didn't see coming!
Check out this file:

It even has some Elisp to compute the number of observed birds
("kryss", as they are called in Swedish). I have 61, that means
not much of an ornithologist, I'm afraid :$
