The beard stripe describes a differently colored, dark area of feathers in the cheek region of different birds. The beard stripe starts at the base of the lower beak or the lower edge of the eye and runs down the cheek, usually tapering, sometimes also bending up to the neck. It lies between the chin and cheek stripes, if there are any. Many bird species, such as hawks , woodpeckers and some songbird species, have a beard streak. The beard stripe is particularly evident in the bearded tit . For some species this spring drawing is eponymous ( Bart Streif Baumsteiger ( Xiphorhynchus chunchotambo ), Bart Streif nuns tyrant ( Xolmis cinereus ), Bart Streif Wren ( Pheugopedius mystacalis ), Bart Streif Zwergtimalie ( Malacopteron magnirostre )).
