Parker Paul recently filmed the birds flying around outside his window for an hour and, in his own words, "used the sky as a blue screen" to create a one-minute-long composite video. It's hard to decide if it's hauntingly beautiful or just plain haunting. The dark Italo disco soundtrack suggests the latter.
It's important to realise that not all of these birds are real. Some are just clones that Paul dropped in to amplify the, shall we say, Hitchcock effect of the whole scene. These big metal birds, however, are all real.
