What did I see?

Got to the playground around 5. Chatting while A- swings. Glance to blue sky and see bird in flight coming my way. Big. Floating closer. Eagle? Wingspan about right. Wings fairly flat. Head looks light. Body's dark. Tail is dark. And long and large, well suited to the bird. Neck doesn't look folded or extended. It's come in from the east just north of where we sit. I'm getting my best view. Still trying to stay engaged in the conversation, but this thing doesn't look like anything. Wings rounded? Pointed? It's turning north. "It'll fly over our house in a minute." Hopeless now. Cormorant? Golden Eagle? Anhinga? LBH?
