When we visit historic art museums, we usually think of Renaissance masterpieces in familiar terms. We imagine grand oil paintings depicting dramatic mythological struggles, elegant portraits of royal families dressed in finest silk, and beautifully idealised pastoral landscapes. For generations, traditional art history has taught us that early modern European painters relied mostly on symbolic conventions or classic biblical scenes to compose their major works. The common belief is that these centuries-old paintings have already been thoroughly analysed and hold few remaining secrets.But a surprising discovery hidden within a seventeenth-century masterpiece introduces a completely different narrative to the intersection of classical art and modern field biology. In an intricate allegorical landscape completed more than four hundred years ago, a sharp-eyed observer spotted a tiny, tucked-away detail that completely rewrites what we know about historical wildlife observations. This subtle stroke of oil paint may have captured a rare predatory behaviour that wildlife experts only recently confirmed through field research.This extraordinary historical overlap was brought to light in a study published in the journal PNAS, titled Natural history on canvas: Brueghel knew about bird-eating noctule bats. The scientific report focuses on an oil-on-copper painting titled Air, painted in 1611 by the Flemish master Jan Brueghel the Elder. The modern analysis suggests that, while zoologists long treated reports of bats hunting migratory birds with scepticism, the painting may depict the phenomenon in plain sight.A rare bat predation scene hidden in a classical paintingTo fully understand why this artistic discovery sent shockwaves through the scientific community, it helps to look at the immense difficulties researchers faced when trying to study these animals in the wild. The species depicted in the canvas is the greater noctule bat, an elusive mammal that flies at high altitudes at night. Because these creatures hunt in darkness more than a kilometre above the ground, observing their feeding habits directly from the forest floor was extremely difficult, so scientists relied on circumstantial clues left behind in roosting sites.The study says field biologists only recently confirmed this bird-hunting behaviour using cutting-edge technology. It was only within the last year that international teams of ecologists successfully attached ultra-lightweight data-recording backpacks to wild greater noctule bats. These high-tech devices captured altitude, flight speed, and sound as the bats made rapid dives to intercept migrating songbirds at night.When Spanish ecologist Pedro Romero-Vidal began examining Jan Brueghel the Elder’s 1611 painting Air as part of a project tracking historical wildlife depictions, he noticed something bizarre in the upper section of the canvas. Surrounded by a chaotic, beautiful flock of more than sixty recognisable bird species, a large flying bat was clearly rendered with a small, feathered songbird clamped firmly inside its jaws. The specific anatomical markers of the painted mammal, including its short rounded ears, narrow wings, and distinctive reddish-brown coat, are consistent with the greater noctule bat.

The remarkable precision of early modern naturalistsThe scene raises questions about how a seventeenth-century artist could depict a behaviour that modern science only recently verified with tracking devices. While classical painters often used animals as moral allegories, the anatomical and behavioural detail in this Flemish painting suggests it may have been based on real-world observation.According to the study’s commentary, Jan Brueghel the Elder was known for his strong dedication to realism, often visiting royal menageries and consulting early naturalists to sketch rare specimens from life. Although the greater noctule bat is not a common sight in the painter’s native Belgium, historical records show that the artist spent significant time travelling through Italy, where the bird-eating mammal maintains a much larger and more active wild population.This discovery highlights the scientific value hidden in major art collections. By suggesting that a Renaissance painter recorded a complex wildlife interaction before modern science accepted it, the study shows that historical art can preserve useful observations of the natural world. Exploring this painting may encourage scientists to look more closely at classical art for ecological clues.
