On the page is the artist's name, which, if you google will give you her website. On it is a link for home goods that she has designed. Unfortunately, you have to log in so I don't know if there's a lamp with the birdcage. The lamp is very inexpensive and I bet that you could recreate it quite easily.
eta: btw, the owner of the photograph got the lamp in Korea at "the Art Box."
I can't find the piece anywhere. So...I would DIY. I'd find a birdcage that you love, and then I'd find a lightbulb cover in the shape of that bird to fit over whatever light fits inside your chose birdcage. You can do this! It will be fun! LOL! Seriously, though, I scoured the interwebz and was unable to find the same piece. Hopefully someone else had better luck, but if not, I think this is a doable DIY piece. We will help!
