A postal worker has had trouble completing his mail route because he keeps getting attacked by falcons.
Ron Eudy, of Abilene, Texas, has been attacked by a group of falcons every day for the past two weeks while he tries to deliver mail along his designated route.
The birds appear to be specifically attacking the postal worker, leaving a thump on his head each time.
There haven't been any other complaints of falcon attacks from residents along Mr Eudy's route.
But every time the mailman makes his deliveries, the falcons begin to circle around him, dipping down to hit him.
'It’s a thump, I promise you,' Mr Eudy, who has worked as a postal worker for 26 years, told KTAB. 'And luckily, it hits me in the head and it’s a bang, it ain’t just a little thump.'
The birds are attracted – or appalled – by a beige-coloured hat the postal worker wears because they leave him alone if he switches head gear.
'I switched hats and when I wear this blue one they don't come after me so it's something about this hat. I don't really know what it is.'
The mailman believes the falcons are trying to protect a nearby nest.
Residents living in the area know a falcon is close by when they see Mr Eudy deliver their mail.
Homeowner Marvin Smith told KTAB: 'I said "Look out Ronnie, here he comes again," and you could hear him hit the top of his hat.'
