Question

Which of the following is not an adaptation of California thrashers to life in the chaparral biome?
a.
a long, curved beak for scratching at the ground
b.
nesting in late March
c.
a preference for walking over flying
d.
nocturnal activity

Answer 1

d. Nocturnal activity

California thrashers are primarily diurnal/crepuscular ground foragers: they use a long, curved bill to rake leaf litter and prefer walking through dense chaparral. Nesting in late March times reproduction with spring food availability and before the dry summer—so nocturnality is not an adaptation for them.
