Walker, Victoria and Arktos have been playing with the pylons, throwing them up in the air and sticking their heads inside them.
The bears, which all live at Highland Wildlife Park near Kingussie, Highlands, received the items after they were no longer needed for roadworks.
The cones were previously used by contractors working on the dualling of the A9 between Kincraig and Dalraddy.
And the materials would normally been disposed of once they were no longer required on the site.
But the wildlife park and contractors have been working together since last year to use of any unwanted material in an innovative way.
Douglas Richardson, Head of Living Collections at RZSS Highland Wildlife Park, said: “We’re delighted to have received the materials.
“The animals have been making good use of the various items, which are being used for enrichment purposes as well as for bedding and flooring in a number of enclosures.”
Paul Gilligan, Construction Manager for Contractor Wills Bros John Paul Joint Venture added: “We are delighted to have had the opportunity to donate these materials to RZSS Highland Wildlife Park, where they can be utilised within the animal enclosures.
“These items were directly sourced from our site clearance activities.
“It is great that we are able to recycle these materials and put them to good use.
“We look forward to seeing the animals enjoying them.”
