This is bird paradise! Whether you’re a highly experienced bird watcher or a novice, you’ll love Ranch De La Osa. When you visit the ranch bring your binoculars, your camera and walking boots because there’s a good chance you’ll see any number of resident and migratory bird species that frequent our area.

Our property borders the 115,000 acre Buenos Aires National Wildlife Refuge which contains extensive grasslands that preserve the endangered masked bobwhite quail and is also home to more than 300 species of birds including hawks, herons, grayhawks, vermilion fly catchers and golden eagles during their seasonal migration. You’ll find species here that thrive in the vast remoteness of our territory. Loggerhead shrikes for example, imperiled elsewhere in the West, are plentiful here.

The Buenos Aires National Wildlife Refuge offers numerous public tours from November through April. For information on group tours and slide programs please click here.

We are more than happy to provide a pack breakfast for those of you that want to explore the bird life before sunrise.
