In Estonia, researchers have reported a significant increase in the grey seal population this winter due to favorable ice conditions for seal pupping. Recent estimates suggest that the population may have grown by 5,000 individuals. To enhance their research capabilities, scientists around Saaremaa have adopted new techniques involving drones for tracking and studying seal activity. This innovative approach allows researchers to capture identifying photographs of seals, which will help in creating a more detailed database of seal sightings.

The researchers not only aim to count the grey seals through aerial imagery but also utilize the drones to create so-called 'passport' images of the seals. By identifying individual seals through photographs, they hope to determine whether these animals have been sighted elsewhere, thus providing a broader understanding of their movement and behavior. The ambition is to make these databases internationally accessible, fostering collaboration and research sharing across the Baltic Sea region, where similar seal photographic initiatives could be rolled out.

This advancement in technology represents a significant stride in wildlife research, as the ability to compare thousands of images quickly via modern computing methods will enhance the efficiency of marine biology studies. As the use of drones in wildlife monitoring becomes more widespread, it could open up new avenues for conservation efforts, improve population tracking, and provide critical insights into the ecological health of marine environments.
