What is unique about the pied kingfisher's breeding behavior?

• A. They migrate to breed far from home
• B. They raise their young with the help of other kingfishers, forming a cooperative breeding group
• C. They nest in trees near water
• D. They lay eggs and abandon nest

Answer: (B)

Cooperative breeding is the idea that extra adults help raise the offspring rather than just the two parents doing all the care. In pied kingfishers, this shows up as helpers at the nest—additional adults or older offspring that feed the chicks, defend the nest, and support the breeders. This extra help increases the chicks’ survival and shares the workload, which is unusual for many kingfishers and birds in general. So the standout feature is raising young with the help of others, forming a cooperative breeding group. The other options don’t match this species’ typical breeding pattern: they aren’t defined by long-distance breeding migrations, nesting in trees, or abandoning nests after laying.
