Albatross-borne altimeters expose the high-flight tail that average altitude can miss
WHAT THE EVIDENCE SAYS
Researchers fitted altimeters and GPS units to three shy albatrosses. The altimeters resolved rapid dynamic-soaring cycles and produced mean flight heights around four metres, broadly consistent with GPS, while better characterizing the right-skewed distribution of higher-altitude flight segments relevant to collision-risk models.
WHY IT MATTERS / OUR READ
For offshore-wind ecology, the tail of the flight-height distribution can matter more than the average. A sensor that resolves short high-altitude excursions could improve the exposure term in collision-risk models when validated at larger scale.
CAVEATS / UNCERTAINTY
This is a three-bird proof of concept rather than a population-level flight-height estimate. The work validates a measurement approach, not collision risk itself, and sensor performance and behavior should be tested across conditions and species.

A three-bird proof of concept found roughly 4 m mean flight heights but a clearer right-skew in altimeter data, potentially improving collision-risk inputs for offshore wind assessments.
