An empty bird's nest made of branches. This is a new emoji included in Emoji 14.0, which is released in September 2021.
🪹 generally means nests, birds
🐦 or home. It may also represent the Beijing National Stadium
🏟, which is known as "Bird's nest" -- so called because it looks like a bird's nest. In China, sometimes 🪹 is used to refer to "empty nest families", where the children of a family are all working away from home and the elderly are left to live alone
😢. This emoji is very similar to 🪹, the difference between them is that one is an empty nest, and the other is a nest with eggs. Related emojis:
