my daughter and i just recently went to a park that has a variety of birds and ducks. after we came back home, we went through a couple of birds books we have to see if we could identify some of the birds. how neat it would of been to have a few birds whistles to play around with, even if those particular birds where not there. yes, we need to begin our orinthology kit, starting with some of these cool whistles from uncommon goods. it doesn't end there either! i love receiving the latest catalog from them because just as their name says, the have a wonderful stock of great and uncommon items. check them out!
