Long, narrow beak
What makes it specialThe bones in its neck are not joined together, so it can turn its head. This helps it move between flooded tree trunks.
Surprising factThe pink gets stronger when it works hard or is excited, like a blush. Males are pinker because of scars from fights.
PopulationTens of thousands in the whole Amazon basin. The number falls by half every ten years.
