The top bird is an Orchard Oriole. There's not as many of these around as there are Baltimore Orioles in our area. A lot of people pass them off as being robins if they're not paying close attention. Orioles are in the same family as blackbirds where as American Robins are in the thrush family.
Looking up at all those treetop warblers can give you one heckuva stiff neck! Sandpipers like this Least Sandpiper allow you to look down and stretch your neck!
