The Hawaiian poʻo-uli, a small bird from the honeycreeper family, was first discovered in 1973. Less than half a century later, it disappeared from the planet.
Declared extinct in 2018, it is one of almost 700 vertebrate species that have been driven to extinction in the last 500 years. According to a United Nations report issued earlier this year to policymakers, one million species are at risk of extinction: Human actions threaten more plants and animals than ever before. Although the precise number of species on the planet is difficult to calculate, recent estimates put it at around 8.7 million.
The plight of the poʻo-uli illustrates a key problem for conservationists: It is difficult to track and monitor populations of endangered species. Despite efforts to tag and locate the dwindling poʻo-uli population, scientists were unable to unite breeding pairs.
Now, technology is offering hope to scientists. Collecting better data and analyzing it more effectively with machine learning and AI allows conservationists to make more targeted and timely interventions.
Here are five ways Microsoft and conservation efforts are coming together to help endangered species.

Identifying lions and giraffes
Facial– and pattern–recognition technology allows researchers to pinpoint and track individual animals, helping scientists monitor populations and their migrations.
However, without the distinctive markings of cheetahs and leopards, it is harder for researchers to identify individual lions. The Lion Identification Network of Collaborators uses facial recognition techniques to monitor population levels. Identification involves taking a high-quality photo and zooming in on areas such as whisker spots – something a computer is more capable of than the human eye. This technology helps reduce reliance on expensive and difficult–to–fit GPS monitors, which can have limited battery life.
Similar technology is being used by researchers from Penn State University and the Wild Nature Institute to study the births, deaths and movements of more than 3,000 giraffes in northern Tanzania.
Habitat loss and illegal hunting for meat have meant giraffe populations have experienced a dramatic decline in recent years. Pattern–recognition technology trained to identify the unique markings on a giraffe’s torso can now process images in minutes, a task that previously took conservationists weeks.
Monitoring the impact of humans on grizzly bear populations
Clayton Lamb, a researcher at the University of Alberta, Canada, is using Microsoft Azure tools along with AI to create a comprehensive analysis of the human and environmental factors limiting grizzly bear density in British Columbia.
With human populations increasingly expanding into areas of wilderness, the grizzly is coming under threat as its habitat is shrinking. These roaming omnivores are particularly sensitive to human disturbance, and globally now live in an area only about half their original range.
Lamb uses DNA sampling and GPS collars to track individual bears in order to better understand the connectivity between populations and their habitats at a granular level. By generating such specific data, he is able to move his work beyond theoretical population ecology and suggest steps to reduce the impact of humans on wildlife populations.
Assessing whale health and feeding patterns
As oceans warm, krill stocks – a critical whale food – are falling, while fishing and commercial exploitation of habitats are also placing a strain on whale populations.
Given the distances whales travel, monitoring their movements using traditional methods is both time-consuming and expensive. Neural networks have allowed scientists to link multiple systems, including satellites, drones and autonomous underwater vehicles, to paint a more comprehensive picture of the migration and health of these great animals.
Tracking penguin populations
Monitoring penguin populations in remote habitats is also difficult work. Identifying colonies often involves looking for hard-to-find markers such as guano stains on rocks of a very similar color.
Ecologist Heather J. Lynch, from the Department of Ecology and Evolution, Stony Brook University, is coupling AI capabilities with predictive population modelling to allow real-time tracking of Antarctic penguins.
She’s using computer vision to search for guano stains in satellite imagery in order to inform and develop the classification algorithms that generate population estimates for colonies.
Protecting elephants from poachers
It is estimated that an elephant was killed every 15 minutes between 2007 and 2014 – and that 25,000 to 35,000 were killed each year by poachers for their ivory.
With huge areas to monitor, defending these animals is a challenge. Resources can be thinly spread, communication can be patchy and gathering usable data tricky.
The Elephant Listening Project is helping protect the threatened forest elephant. Teams at Cornell University in Ithaca, New York, with assistance from Conservation Metrics based in Santa Cruz, California, are using AI to identify and analyze recordings of elephant calls, helping to create an “elephant dictionary” by matching noises to behavior.
A growing understanding of elephant communication is allowing researchers to better appreciate the impact of factors such as oil exploration, logging and poaching, as well as enabling them to coordinate conservation efforts more efficiently.
