Juvenile Golden Eagle In Flight

This is one of the better views I have of the field marks of a juvenile Golden Eagle in flight.

In the field Golden Eagles can be difficult to classify as to specific age because there’s much variation among individuals and age-related traits of juveniles, sub-adults and adults are often obscured. Poor light on the underside of an eagle in flight when it’s high overhead and far away (as is often the case with this species) doesn’t make the daunting task any easier.

I photographed this juvenile (mostly in its first plumage) almost exactly a year ago as it soared overhead in Box Elder County, Utah. The brightly lit golden nape easily identifies it as a Golden Eagle. I’m quite happy with the image because of its sharpness and good detail (especially for a bird flying overhead with shaded underparts), the slightly open beak and I even have a good look at the eye with a catch light which is often missing in images like this.

But mostly I appreciate the good look at some of the field marks of the juvenile. Both juveniles and sub-adults have varying amounts of white in the tail and wings. Those whites gradually become darker as they age but in juveniles the white in the tail typically covers more than half of its entire ventral surface and many of their remiges (wing primary flight feathers) have a white base which produces the distinctive white wing patch of the juvenile. White wing patches vary considerably in size among juveniles. Based on the emerging primary in the right wing and the time of year I suspect this bird is transitioning into sub-adult I.

Adults are completely dark and show only faint gray mottling in the wings and tail. The amount of white in the tail and remiges of sub-adults (I-IV) is intermediate and variable.

Note: Aging Golden Eagles can be tricky even for experts and I’m far from an authority on the subject so I’d appreciate knowing about it if I’ve made any glaring errors.

  5. Wow, wow and wow.
    This is a stunning image.
    I have had a v good morning. A balloon festival at dawn, followed by a Golden Eagle. Hard to beat.

  6. Don’t do it Patty. You will get a splat on your head! Ron, you are too funny. Wonderful picture. They are amazing birds. The size of their feet!

  7. THIS is the image I’d like to put on my ceiling!!!!!

  8. Have no words …just OMG!!!!!!!!!!!

  9. Ron, where is the best place to see Golden Eagles in Utah?

    • Don’t know about the “best” place, they’re nearly always elusive. Almost anywhere in Utah that has wild, open country close to mountains, cliffs and hills could have them – especially if rabbits are plentiful.

  10. A totally magnificent bird which you captured so well. I can understand why your viewing of these birds is special. I sure hope I get to see one sometime.
    Thanks, Ron

  11. Gorgeous. Gorgeous. Gorgeous. Totally worth losing an hour of sleep to wake up to this magnificent creature!

  12. Nice photo Ron. I have never seen a Golden Eagle in the wild. I have taken photos of juvenile Bald Eagles here. I know they can be see at many locations throughout Arizona and hopefully I will get to see one one of these days.

  13. This answers a question I’ve pondered for years. Thanks!

  14. They are gorgeous birds.

  15. Excellent Ron, just beautiful!
    Several years ago had one fly low over our property traversing the border of a lake. Very surprising for me to see a Golden in VT, but they are seen from time to time. These field marks are what gave it away as a Golden, plus the gold feathers on the neck when it is low enough to be seen. I am in awe of Golden’s, love em!!

  16. Beautiful photo, Ron and the tutorial is great….. I find that the white patch on the wings is something that is usually visible even when the golden nap isn’t and is one thing I look for. The underside of tail has been confusing to me over time – thx for that tip! 🙂

    • Thank you, Judy. We usually have to have pretty good light on the golden nape to see or photograph it well. When we don’t it can be very difficult or impossible to see.
