Jay Day is a reimagined urban jay habitat to encourage visitors to consider integrating live plants into their bird-feeding regime and focusing the resources they provide on non-typical feeder species. The Eurasian jay (Garrulus glandarius) uses hypnum moss for nut caching, so to encourage it into the space, the substrate of the balcony is a carpet of green moss overlaid with a metal grate for human access. Vertically, various ‘hatch’ latticeworks frame the view and interweave utility for humans, birds and insects.
