Call-of-love / Bird cage


Taking a walk with caged birds is a common scene in China. Call-of-love Birdcage is without real birds. The simulation bird absorbs solar energy and emits a certain frequency sound wave, which could attract birds to forage and inhabit. Numerous empty-nest elderly are alone at home with lonely hearts, starving for companionship and love. With the cage, they can feed birds in the park, enjoy the beautiful scenery and chat with people to reduce loneliness and gain warmth. The design is not just a call for the love of birds and nature. It is also the call for attention to physical and psychological health of the empty nesters.
