In my quest to come to understand how to identify passage Merlins from haggard (adult) Merlins I found the following site. Kinda cool!
Of course, this comes with the disclaimer that all native bird species are protected, and to possess even their molted feathers is illegal. Falconers are allowed to keep the feathers from their legally acquired and kept under permit birds, so we may use those molted feathers to repair (imp) any broken feathers on that bird, or future birds we may have under our permit.
