I suppose their light gathering abilities work well enough in dim conditions to create some overlap with the nightly arrival of their nocturnal relatives. I’ve often seen Northern Harriers overlap with Short-eared Owls as the night shift swings into action.
Great Egrets also fiddle around in the shallows when the evening comes. Perhaps it is because I’m often an urban birder that I see more birds out taking advantage of the unintentional light leaking from our homes and streets.
And I’ll see you all in two weeks.
