"I am an adult lego enthusiast and i've bought the birds set not only as a lego building challenge but also to display behind glass as ornaments. I am very impressed with the quality of the whole set ie: the box, information booklets and the pieces themselves. Once the birds are built they look superb and they each stand on their own plinth with a plaque giving the birds latin name.. One question - why do LEGO discontinue their sets after such a short time? I was hoping to purchase a set for my daughter but have already found it to be retired and prices have soared within the space of a couple of weeks on sites such as EBAy and Amazon !"
