One afternoon, last month, I arrived home and saw a familiar bird in our common grassed area. We have many birds in our large townhouse complex (and our backyard) but this was one I hadn't seen in the complex before.
In the afternoon shade of the many Macadamia trees, was a Sulpuur-crested Cockatoo picking up numerous Macadamia nuts. I wasn't aware at the time (but I did Google it afterwards) that these birds beaks are strong enough to crack the shells of Macadamia nuts. I also discovered that Macadamia trees are a favourite.
