| Structure and moult of wing and tail of a full-grown Ostrich, Struthio camelus, are described. In the wing, at least three feather generations could be recognized. The pattern of moult is more or less symmetrical in both wings and the sequence of feather replacement is not random. The tail consisted of 93 feathers of two different generations. Moult in the tail proceeds asymmetrically and seems to be fully irregular. The phylogenetic significance of these findings is discussed. |

| Using light microscopy, a method has been developed for the identification of feathers and feather fragments collected after collisions between birds and aircraft. Characters of the downy barbules of feathers are described for 22 orders of birds. The use of a key in combination with the macroscopic method of comparing feathers with bird skins in a museum collection results in identification to order or family level in 97% of the analysed bird strikes. Application of the method to other fields of biological research including taxonomy is discussed. |
