アカギツネ
Red fox sparrows may nest on the ground, or in shrubs and trees. They typically nest less than 2 metres off the ground. Clutch consists of 3–5 pale blue to pale green eggs that are thickly spotted with brown. Incubation lasts between 12 and 14 days. The eggs are mostly incubated by the female though both sexes feed the young. Young birds are altricial and fledge in 9 to 11 days.
