What must remain in the nest when taking eyasses?

• A. All eyasses
• B. At least one eyass
• C. Only eggs
• D. No eyasses

Answer: (B)

When removing eyasses from a nest, you must leave at least one eyass behind. This helps protect the nesting pair and the nest’s chance of success by ensuring there’s still a chick to be fed and raised, which reduces disturbance to the breeding birds and the risk of nest abandonment. Removing all eyasses would end the brood and can disrupt the parents’ behavior and the nest’s future success. So the best practice is to leave at least one eyass in the nest.
