The common swift (Apus apus) has been shown by tracking devices to remain continuously airborne for up to 10 months at a stretch outside the breeding season, landing only to nest — the longest sustained flight duration documented in any bird, during which the birds eat, sleep, and even mate on the wing.
The question, scope, and sources behind this Registry record.
The common swift (Apus apus) has been shown by tracking devices to remain continuously airborne for up to 10 months at a stretch outside the breeding season, landing only to nest — the longest sustained flight duration documented in any bird, during which the birds eat, sleep, and even mate on the wing.
The longest continuous period a bird has been tracked remaining airborne without landing, as recorded by miniature accelerometer/GPS tags, distinct from total migratory distance covered.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
