This nest was intact (to a human perspective at least). One of the pair was hunkered down in the nest, and the other was on the next light pole having a fish dinner.
Last summer a pair of osprey lived atop one of the light poles at the baseball stadium. Over the winter the next disappeared--whether from the elements, or a deliberate cherry picker cleanup we don't know. In late March a pair of osprey were back.
Over Easter weekend, so sign of the pair or a nest.
