What material does the black-naped monarch use to decorate its nest?
A Small pebbles
B Spider-egg cases
C Feathers of other birds
Fact: The black-naped monarch adds a unique touch to its nest by decorating it with spider-egg cases. While the female carefully builds the cup-shaped nest, the male stands guard. Once the nest is completed, she lays a typical clutch of three eggs, which both parents take turns incubating. After about 12 days, the chicks hatch, and both parents share the responsibility of feeding them.
Correct Answer: Spider-egg cases
