Introduction
One of the more revealing lessons from recent U.S. military UAP investigations is that birds can look surprisingly unlike birds when viewed through long-range infrared sensors. On some recordings, individual birds or small groups appear as glowing dots, featureless spheres, or pulsing “orbs” with no visible wings, feathers or body shape. The effect can be strong enough that the footage is initially reported as unidentified. AARO’s released case material shows that this is not a theoretical possibility but a recurring real-world source of misidentification. In several resolved cases, analysts concluded with high confidence that unusual infrared targets were birds whose appearance had been altered by sensor limitations, distance and flight behaviour.

How infrared video hides bird shape
Infrared systems do not record the world in the same way as ordinary cameras. Instead of visible colours and textures, they display differences in heat or thermal contrast. At long distances, a bird may occupy only a handful of pixels in the image. Once that happens, most anatomical detail disappears.
Several factors combine to produce an orb-like appearance:
- Extreme range: A distant bird may be smaller than the sensor’s resolving capability.
- Thermal averaging: Warm body parts blend together into a single bright spot.
- Image processing: Tracking algorithms and video compression can smooth irregular shapes into compact blobs.
- Narrow fields of view: Highly zoomed military sensors often prioritise detection and tracking over recognisable visual detail.
The result is that a bird can cease to resemble a bird and instead appear as a small luminous object with no obvious structure. This effect is especially pronounced on infrared footage released from military platforms, where operators are often tracking distant airborne targets rather than filming wildlife. [AARO]
Importantly, the disappearance of visible wings does not mean the wings are absent. It usually means the wings are too small, too blurred, or too thermally indistinct to be separated from the rest of the target in the available pixels.
Wing beats, pulsing and pixelation
A common feature of bird-related infrared footage is an apparent rhythmic pulsing. To an observer unfamiliar with thermal imaging, the object can seem to be changing energy output, flashing, or exhibiting unusual propulsion effects.
AARO’s analysis points to a much simpler explanation: wing beats. In its Europe 2023 case PR-016, the office noted that the targets displayed a “pulsating infrared return at a frequency consistent with wing beats”. Analysts considered this one of the key indicators that the objects were birds rather than anomalous craft.

This pulsing occurs because each wing stroke alters the target’s apparent shape and thermal presentation. As wings move through the sensor’s line of sight:
- The apparent area of the target expands and contracts.
- Thermal reflections and emissions change slightly.
- A tiny object spreads across different pixels from frame to frame.
- Compression and interpolation can exaggerate the brightness variation.
Viewed in isolation, the object may seem to brighten and dim rhythmically. Viewed with knowledge of bird flight mechanics, the pattern becomes a useful identification clue.
Pixelation amplifies the effect. When a target occupies only a few pixels, even small changes in shape can produce disproportionately large changes in brightness and apparent size. A bird’s normal wing motion can therefore create an object that looks like a glowing sphere that repeatedly swells, contracts or flickers.
What PR-016 adds to the pattern
PR-016 is significant because it demonstrates how analysts move from a mysterious-looking infrared object to a conventional explanation. The case involved twenty-five seconds of infrared footage collected from a U.S. military platform over Europe in 2023. AARO assessed with greater than 95% confidence that the objects were birds.

The assessment did not rely on a single clue. Instead, AARO pointed to a combination of indicators:
- Strong visual similarity to previously resolved bird imagery.
- Relative positioning consistent with birds flying together.
- Behaviour associated with energy-conserving flight formations.
- Infrared pulsing matching expected wing-beat frequencies. [AARO]aaro.milAARO HomeIncludes windborne debris like plastic bags and mylar balloons, or birds. These may appear anomalous due to their unpredictable…
This is an important pattern within modern resolved UAP investigations. Identification often comes not from one dramatic revelation but from multiple ordinary characteristics lining up. A shape that initially looks like an orb becomes less mysterious when its movement, spacing and brightness fluctuations all match known bird behaviour.
The case also illustrates a broader lesson for interpreting infrared UAP footage. An apparently exotic object may be the product of limited visual information rather than an exotic phenomenon. When distance strips away detail and a thermal sensor reduces a living animal to a few bright pixels, familiar creatures can acquire an unfamiliar appearance. In that sense, the “infrared orb” is often not a separate object at all—it is simply what a bird looks like when viewed through the constraints of a military sensor system.
