Bullock's Oriole up very close and personal

Landbird migration has been in full swing this week in riparian areas in the Canon City, CO area. I have apparently been living right as this oriole flew in less than 15 feet above me providing a wonderful opportunity for close-up photos.

From the plumage characteristics this bird is a female or immature. The mostly flesh/pinkish colored lower mandible (with rustyish markings) makes me think this may be a juvenile. Birds of North America online calls the lower mandible "bluish gray, dull white at tip and doesn't mention anything about juvenile birds nor could I find anything online or in my books about it. Note: I didn't do any color modification or other editing of these pics with the exception of some cropping to preserve color and shading. SeEtta
