Song development in the zebra finch and other estrildid finches
Root crop cleaning apparatus including a pair of adjacent, counterrotating cleaning rolls arranged in root crop receiving relation, the resilient disks on the one roll being yieldable axially and cooperable with the axially extending gaps between the rods on the other roll to permit rocks and other foreign objects to pass between the rolls without causing damage to the apparatus.

Influence of adult courtship experience on the development of sexual preferences in zebra finch males
Young zebra finch, Taeniopygia guttata castanotis, males were raised by Bengalese finch, Lonchura striata, foster parents until day 35, 40 or 50 of age, respectively. Following isolation until dayExpand
Behavioral and hormonal responses of male zebra finches to antiandrogens
The results show that injections of CyA depress the sexual activity of the birds as measured by the amount of courtship song and the antiandrogenic activity of Cy probably is neutralized by this stimulated testosterone production. Expand
