This page does not pretend to be relevant to the non-bird obsessed general public. If you do not love birds, or if you think birds are cute, these posts will act as a thunderous sedative upon your head. If, however, you have a very cool, very deep connection with birds. And if you have already eaten up the majority of bird literature and found it to be frustrating, in that it seems to always subsist gamely at entry level. Well, then maybe this page may contain some links of interest.
