Scarlet ibises have red bills and feet however the bill is sometimes blackish, especially toward the end. They have a long, narrow, decurved bill. Their legs and neck are long and extended in flight. A juvenile scarlet ibis is a mix of grey, brown, and white. Though it spends most of its time on foot or wading through water, the bird is a very strong flyer. The life span of the scarlet ibis is approximately 16 years in the wild and 20 years in captivity.
