DAZ has some bird props in their Free Archive. A nest, a birdcage, maybe some other stuff.

Ken includes props in his Songbird Remix character packs, so if you have any of those, check the props section of your runtime. The European birds pack comes with a really nice berry branch for the birds to sit on.

Also check out Ken's site (see link). He's got some extras for his songbird packs, including some free props. (Birdhouses, trees, etc.)
