(Inside Science) — Researchers were flummoxed when their motion-triggered cameras snapped photographs of birds clinging to giraffes’ crotches for the first time. But after sifting through more than 1 million images from the Serengeti, they discovered that the yellow-billed oxpecker regularly nested in unusual spots.
