Footage has emerged from the US of an apparently fearless deer wandering through a busy park during the day.

The video, filmed on Sunday at Mansion Park in Manitou Springs, Colorado, shows the deer strolling through the park, snacking on leaves, seemingly unworried by all the people and traffic around her.

"She just walked right out in front of us standing on the sidewalk, crossed the street and went about her business," the filmer wrote online.
