If you've spent any time birdwatching, you might have marveled at some species' ability to stick effortless landings on thorny plants without suffering painful pokes. Puncture-proof landing techniques are often seen in passerine birds with desert habitats—like this verdin, native to the American Southwest and northern Mexico. These aridity-adapted avians are so lightweight that most cactus spines can't penetrate their tough toes, which are covered in hard scales and contain few nerve endings. On top of that, the birds boast highly evolved spatial awareness that tells them exactly where their landing gear can get a safe grip.
