Cuckoo birds are brood parasites, they use other birds’ nests to grow their hatchlings. Mother Cuckoo carefully selects existing nests and puts an egg, only one egg per nest. When Baby Cuckoo hatches, most of the time before other eggs, it just pushes them out the nest. This is its very first instinct, probably not the most rewarding one… Adoptive parents are now only focused on Baby Cuckoo and feed it graciously, with profusion.
This gave me an idea for a new Jaluino family board…
