Taken today in Maricopa County, AZ. Tail didn’t look red to me.

Immature Red-tailed Hawk

Juvenile Red-tailed Hawks do not develop the red tail until they are two years old.

Actually about 1.25-1.5 years of age

That's why I said "Immature" not juvenile.

They don't become "immatures" until they start conducting their 2nd prebasic molt. That molt, depending upon where it was produced, could start soon; certainly in the next couple months. We can see that this individual has not started dropping flight feathers, so until then, it's a juvenile.

Interesting... I always assumed Juveniles were extremely young birds. Learned something new today! Thanks!
