I love birds, but I just can't stand seeing them in cages.
Today I found a great answer to this problem! Nestlin is a multifunctional wine packaging made from wood designed by Igor Solovyov: after using it to carry wine, it can be used as a bird nesting box, being therefore sustainable and earth friendly. There is also a little hole for you to insert a stick to create a perch for the birds. Cute!!
