Wouter Halfwerk, a behavioural ecologist at Leiden University in the Netherlands has published a paper demonstrating that some birds find themselves forced to change their mating songs as they compete with anthropological noise pollution. Chicks are also becoming malnourished, as their parents cannot hear them begging for food. This is not shocking, it just demonstrates how deaf we are to nature’s beauty: sacrificing birdsong (which enhances wellbeing), rather than find alternatives to noisy & polluting transportation. Is it the responsibility of designers, architects or city planners to integrate wildlife into urban spaces? What does that look like? Sparrow Speculations is a speculative design piece in response to this question. It is an ‘amplification device’, allowing birds to have agency and control over the volume of their calls. Over time, perhaps the birds will adapt to use the cone as an evolutionary tool. Or, is it simply a further disruption to an already broken ecosystem?
