Structural engineer in action: Xây Tổ Ấm
Not to detract from the sheer magic of it, but in practical terms, how MANY trips would a bird have to make with that tiny little quantity of mud/clay it could carry? (and how far from the nest is the source?) Bao nhiêu cố gắng, bao nhiêu công lao, bao nhiêu cặm cụi, vượt biển, nối nguồn?
If you take the construction of a “circular bowl” in your stride as instinctive – how the heck does the bird come up with the windbreak/entrance design that shields the eggs/chicks from the elements – and at what point in fashioning the bowl do they start to construct it? Tất cả chỉ để quây tròn một Tổ Ấm… Khởi đầu từ đâu nhỉ?
