This photo from Kingsville, Texas showsshows:
- dark patagial markings under the leading edge of the wing (a red-tailed hawk marker)
- dark banding on the leg feathers like your bird
- the top of the tail has narrow dark banding like your bird
- the underside of the tail is basically white like your bird
- white chest and dark markings on the belly like your bird
Here is a photo of a different juvenile red-tailed also from the Kingsville area:
The tail is white underneath and the top has the narrow dark bands of a juvenile red-tailed.
A western redtail with have very different markings underneath the wings from an eastern, but I’m not sure which would be most likely to be in Grace’s area.
