Being a semi-noob birder, I'm going to say I'm not 100% sure of what I saw, never having watched Orioles do this ...
I think I spotted a Baltimore Oriole nest under construction yesterday. With binoculars I was able to follow a male carrying nest material from the lake side of the path to the tall maple tree on the swan pen 'island'. He stayed up there a while and I was able to see the sack-shaped nest as leaves moved with the wind. I gather the female was nearby or busy building. It will likely be hidden once the tree finishes leafing out. The nest is on the north-ish side (facing the lake) of the tallest maple on the island, a few feet from the top.
