Did you know? American kestrels can be reliably sexed as early as 14 days old! American kestrels exhibit sexual dimorphism, meaning the females and males have different plumages. For many raptors, the feathers they grow before leaving the nest are often browner or streakier than the adults of their species. But with kestrels, the young take to the sky for the first time with the same striking patterns as their parents! It’s this combination which allows us to distinguish between the females and males at such a young age. Fun Fact! This year 47% of our nestlings were female while 53% were male.![]()

This photo, featuring two young kestrels, shows a comparison of the flight feathers of the female (left) and the male (right). The female’s wings are rusty brown with heavy black barring, while the male (right) has bluish, slate gray feathers with black. If you look closely, you can also see that the female has a similar pattern of barring on her tail, while the male will grow a rusty brown tail with a band of black at the tip.
