Bird ID Help
Hi,
Can anyone tell me what this bird is? Took this in Southern Florida this morning. Someone suggested it may be a juvenile bald eagle, but I really can't tell.

Thanks.

The long and striped tail pattern suggests hawk, not eagle.
Sure not certain, but it looks like a dark morph, juvenile red-tail hawk to me.
Let's see what others think-

Sandy has it pegged as a juv. red-tailed hawk. However, from this view its plumage appears to me to be of normal chromotype for a juvenile...neither dark nor light.

structurally, the tail looks rather long for a redtail--I think it's a juvenile red-shouldered. the banding on the tail is a little on the strong side for a redtail and fits RSHA, as does the hint of a pale crescent near the wingtips.

I believe Dave has it right. I observed a pair of Red-tailed hawks frequently, that had a nest in an area that I visited weekly or bi-weekly for several months. One of their 2 surviving-I did spot 3 chicks at one time-was very much like this bird when he fledged.
I don't have a photo of dorsal view but did get a few from ventral aspect.
I seem to have a glitch when I try to add photos to replies but would be happy to share if you wished to email me.
have a great day.

An aspect of the pictured buteo that does, in my experience, aid in differentiating some raptor species (other features being inconclusive....) is the shape and mass of the beak and cere relative to the shape and size of the head. In this buteo, the contours of the beak and cere extend smoothly and directly from the contours of the front of the head, something like an extention of a somewhat conical face ( typical for a red-tail) while the beak of a red-shouldered is less massive, more delicate, and extends discretely and abruptly from the "face" more as a small cone attached to a large sphere. Check out some shots of the faces of both species to see what I mean.
As i've mentioned on several occasions in this forum beak shape and mass can also be useful in differentiating silhouettes of bald and golden eagles and also in differentiating sharp-shinned and Cooper's hawk individuals of similar size.

I'm outnumbered here but I'm sticking with Red-shouldered on this bird. The strongly barred tail and the pale crescent on the wings are among the most important marks for RSHA. When I have time I'll try to find some other photos to post for comparison.

I'm supporting Brian because of the translucent crescent across outer primaries (from Sibley's Field Guide). Believe it is a juvenile.
There is also a Florida subspecies for this bird, which could cause difficulties in ID.
