Courtship display behavior influences tail myology in Centrocercus minimus (Gunnison sage‐grouse)
Courtship displays among birds are widespread, particularly those which incorporate raised tail feathers for extended periods of time. The Gunnison sage‐grouse (Centrocercus minimus) is such a species. When we compared the tail muscles of the sage‐grouse to birds which do not engage in erected tail fan postures, both morphology proportional mass ...

Aircraft Collisions With Birds (Order Falconiformes and Accipitriformes)
Statistical data on aircraft collisions with birds of prey (Falconiformes and Accipitriformes) are analysed. The basis of the analysis was the results of the IPEE RAS study. The reasons and factors attracting birds of prey to airfields are considered. In

Sternum morphology varies among birds and is a function of body mass and order. The area of the sternum is inversely related to the area of the keel suggesting that the increase in bone mass associated with a large keel has been mitigated by a reduction in bone mass of the sternum.
