Question

from eggs!
1 when spring is in the air, eggs are in nests at national wildlife refuges from coast to coast and beyond. . . .
2 we asked paul baicich, co - author of
ests, eggs and nestlings of north american birds\ and a friends of the migratory bird/duck stamp board member, to point out a few distinctive characteristics of eggs.
3 there is a reason some eggs are white and some are colored, baicich says.
4 white eggs in the wild belong predominantly to cavity nesters - birds that nest in deep holes in trees or terrain. because the eggs are white, the adult birds can see them in the dark cavities.
5 colored eggs in the wild generally belong to birds that nest in comparatively open areas on the ground, baicich says. because eggs in ground nests have color, they are harder for predators to find.
(from \eggs!\ by bill obrian, u.s. fish and wildlife service)
based on the passage, what are two ways the color of birds eggs is important?
□ 1. color helps adult birds avoid unfamiliar eggs.
□ 2. color helps adult birds decide where to lay eggs.
□ 3. color helps keep the eggs hidden from predators.
□ 4. color helps researchers study eggs from a distance.
□ 5. color helps adult birds see their eggs in dark places.

Explanation:

• For option 3: The passage states that colored eggs in ground nests (which are in open areas) are harder for predators to find, so color helps keep eggs hidden from predators.
• For option 5: The passage mentions that white eggs (in dark cavities) allow adult birds to see them, which implies that color (in this case, white as a color - like characteristic in the context of visibility in dark places) helps adult birds see their eggs in dark places.

Answer:

1. Color helps keep the eggs hidden from predators.
2. Color helps adult birds see their eggs in dark places.
