Do I need property release if I shoot animals in a nature reserve?

I have some footage I took while at a wildlife park. I have some footage of birds, fish and other animals. Can I sell these as royalty free or do I need any type of release as I shot them at a specific park? Thank you.

did the ticket say no commercial photography/video?

Normally if it's a paid admission to any place or any business then there might be commercial photo restrictions.

Getting a property release from a National Park can be ...... a looooong ordeal. Many of us have shot in national parks they look the same as any other forest in the world. A casual photographer is not the same as a full filming crew. I would not bother. A tree, a creek, a leave is the same where ever you are.

And the National Park restriction and extra fees were only meant to be charged if the Park had extra expenses such as security or staying open longer due to the film or movie being made. Local Parks are abusing the law.

Do they have identifiable faces, trademarks or logos?

If yes>>you need a model or property release.
If not>>you do not need any release.

I don't think you need to worry about a property release for the park but you absolutely must have model releases for any of the animals filmed.

Ok, Thank you all. I was not sure if and how I could proceed with this idea.

Hi Jordan,
We film in South Africa's National Parks and we try to always get location releases from the authorities. We sell our wildlife and landscape footage from those parks and so we feel it's only fair to pay the filming fees expected.
We believe in karma and so far we've sold a fair amount from our national parks collection! So long may it last!
Hope that helps!
Cheers,
Susan.

Susan,

Depend on how much your Karma worth! Many years ago, a National Trust worker asked me to donate 2,000 pound for photographing in their property. He thought I was from one of those rich organization like NHK, but I was just by myself---one single photographer, not film crew. In my case, National Trust worker's Karma is very bad. IMO :D

PS Looking at your South African wildlife shots and interior museum shot, and they seem don't have property releases. Do I make a mistake that Karma is not that important to you guys anyway! :D
