The simple answer is that the choice is up to you. There are really no “rules,” no do’s and don’ts with thematic collecting. You will quickly discover for yourself what interests you most and what you want to collect. It is probable that over time you will develop your own specific areas of interest. For example, many members are also keen ornithologists and will only collect identifiable bird species. However, some might also include domestic birds in their collections; others might include symbolic birds such as Doves of peace or coats-of-arms. Some only collect used stamps, others only mint. Some might collect covers, and others seek out mini-sheets. There are no hard lines and it is really up to you to decide what aspect of bird stamps you want to build your collection on. Our advice: Go with what interests you.
