Ter kennisname voor de geintesseerden, reactie van de Feather Research Group (via de NHBS):
"In your catalogue, you have announced the Passerine volume of the Atlas of Feathers for Western Paleactic Birds to come out this month and I had indeed planned to be finished by this time. I have been continually working on the illustrations of feathers over the past year, every day from early in the morning till late at night. The most difficult task has been accomplished. Now there are illustrations ready for all 600 Passerine species, which show at least one plumage per species, for most of the species even two plumages. There are only 65 species left for which the illustrations of a second plumage are not yet ready. This is what I am currently working on and it will probably take me until March next year. The juxtaposition of two different plumages per species makes our Atlas of Feathers particularly valuable because it shows the range of variation within each species.
Next year, we will celebrate the 50-year jubilee of our Feather Research Group, which was founded in 1972. So 2022 will be a good year to bring out the first volume of our Atlas of Feathers series to celebrate our golden jubilee. In the meantime, I can recommend the book by Cloé Fraigneau titled Feathers – An Identification Guide to the Feathers of Western European Birds, which is the best feather identification book so far. You already carry this book in your catalogue. If you like, you can link a recommendation to this book on the catalogue page presenting the Atlas of Feathers for Western Palearctic Birds.
I suggest you change the publication date for the Passerine volume of our Atlas of Feathers to December 2022 (hopefully it ready before then) and the publication date for the Non-Passerine volume to December 2024 (an incredible amount of work still has to be done for this). I am not sure if the Non-Passerine volume can go into as much detail as the Passerine volume does, considering that the preparation of the Passerine volume already took 24 years".
