Filbert paintbrush Filbert paintbrush The Filbert paintbrush is a paintbrush used in artwork. It has a thick ferrule and hairs that are, on average, medium to long hairs in the shape of an oval. Filberts are particularly effective in blending work, usually of a figurative nature. Many artists agree that natural fibers work best for filberts because the hairs stick together better when wet. Hairs that can be used are sable, mongoose, bristle, badger and synthetic. Media most likely to have paint applied to by a filbert are oil, acrylic and decorative surfaces.

Dietary biology of the golden eagle of the diet. Everything in this diverse family from least weasels ("Mustela nivalis"), the smallest mammalian carnivore, to wolverines ("Gulo gulo"), the largest terrestrial mustelid, have turned up as prey in golden eagle nests. The members of this family which are most regularly hunted are probably the martens, such as the American marten ("Martes americanus"), pine marten ("Martes martes") and beech marten. The young of larger species are also occasionally hunted in Scotland and Ireland, including Eurasian otters ("Lutra lutra") and Eurasian badgers ("Meles meles"). Similarly, amongst wolverines, “young and inexperienced” specimens are usually targeted as prey by golden eagles.
