The biodiversity of our planet is rapidly declining. We’ve likely reached a tipping point where it is crucial to use every tool at our disposal to help preserve what remains. That’s why I am pleased to announce SPARROW—Solar-Powered Acoustic and Remote Recording Observation Watch, developed by Microsoft’s AI for Good Lab. SPARROW is an AI-powered edge computing solution designed to operate autonomously in the most remote corners of the planet. Solar-powered and equipped with advanced sensors, it collects biodiversity data—from camera traps, acoustic monitors, and other environmental detectors—that are processed using our most advanced PyTorch-based wildlife AI models on low-energy edge GPUs. The resulting critical information is then transmitted via low-Earth orbit satellites directly to the cloud, allowing researchers to access fresh, actionable insights in real time, no matter where they are.
Think of SPARROW as a network of Earth-bound satellites, quietly observing and reporting on the health of our ecosystems without disrupting them. By leveraging solar energy, these devices can run for a long time, minimizing their footprint and any potential harm to the environment.
The Biodiversity Crisis
Over the past fifty years, we have witnessed a troubling erosion of our planet’s biodiversity. According to the WWF’s Living Planet Report, populations of monitored vertebrate species have decreased by an average of nearly 70% since 1970, and some species have vanished entirely or stand on the brink of extinction. This is not just a statistic; it’s a stark reminder that the world we share with countless other forms of life is at a critical tipping point.
Yet, even in the face of this crisis, there are stories of hope, collaboration, and renewed resilience. The rebound of species like the Southern White Rhinoceros, the Iberian lynx, or the mountain gorilla demonstrates that when people come together, we can change the trajectory. The global community can and must work together to restore and protect the natural world.
A critical element of this work is measurement—understanding whether efforts are achieving the intended impact. You cannot improve what you cannot measure. To restore habitats, safeguard endangered species, and ensure long-term biodiversity, we first must gain accurate insights into our environment and the creatures that inhabit it. This is why, for decades, researchers have turned to technology, including camera traps and acoustic sensors, to gather data on wildlife populations and ecosystem health.
At Microsoft’s AI for Good Labwe’ve been proud to support these efforts from the very beginning. Initiatives like the MegaDetector and PyTorch Wildlife have provided powerful AI models that help scientists swiftly analyze the vast amounts of data they collect. Today, more than 18,000 researchers and organizations worldwide rely on these tools to monitor species and landscapes. Our most recent project—codenamed Macaw—has been deployed in partnership with organizations like the Humboldt Institute and the SINCHI Institute in the Amazon, where it helps track the Amazon rainforest’s biodiversity and overall health in real time.
Still, all these advances in AI and analytics hinge on a single, daunting challenge: data collection. Today, many biodiversity projects rely on camera traps and sensor arrays that must be physically retrieved, often from remote, difficult-to-access locations. In many cases, these environments are so remote—deep in rainforests, on windswept savannas, or in rugged mountain ranges—that human presence is rare, if not impossible. Ironically, these are precisely the places where we most need real-time information to understand the ecosystems at risk.

Recognizing this challenge, we set out to create SPARROW. This first-of-its-kind solution redefines how biodiversity data is collected. With LEO satellite connectivity, SPARROW can transmit data from some of the planet’s most isolated regions directly to the cloud.
What truly sets SPARROW apart is its commitment to openness. Every aspect of SPARROW—from its software and hardware plans to its 3D-printable designs—will be open source. This approach empowers research teams, NGOs, and citizen scientists to build, deploy, and adapt their own SPARROW devices. By fostering a global community of innovators, we hope to accelerate progress in biodiversity research and conservation.
The road ahead
Over the next three months, we will deploy several SPARROW devices to field sites across North and South America, including Colombia, as part of Project Guacamaya. By Q2 2025, we aim to refine the solution and ensure its reliability, at which point we will make all plans, designs, and code publicly available. By the end of 2025, our goal is to have SPARROW devices operational on every continent, serving as critical nodes in the global conservation network.
It’s clear that the next phase of biodiversity protection demands both innovation and cooperation on a planetary scale. With SPARROW, we hope to help researchers measure our world more accurately, intervene more effectively, and ultimately preserve the incredible web of life that sustains us all. We look forward to partnering with conservationists, governments, and other stakeholders to turn this vision into reality.
Because when we empower the world’s scientists with the right tools, we take a critical step toward safeguarding the richness and diversity of life on Earth for generations to come.
