This book examines certain the new aspects of a anatomy and biomechanics of the hip joint of the penguins, as well as humans. New data on the role of the ligament of the femoral head when walking and maintaining different types of vertical postures. Initially, this manuscript intended for a narrow circle of people, therefore it made with a smile. Perhaps, our smile will make you smile  also, in some fragments.

Penguins are considered among the most popular animals for zoo and aquarium visitors to observe. Swimming is considered a desirable activity, both for the visitor experience and the welfare of the penguins. However, little is known about the amount of time exhibited penguins spend swimming, or how such swimming is related to regular feeding events. We examined the effects of introducing live prey in the form of trout on 22 Humboldt penguins living at the Woodland Park Zoo. Of primary interest was how the live feeds changed (1) daily and hourly swimming activity, and (2) variability in enclosure use. We hypothesized that the live feedings would increase swimming activity prior to and during the delivery of the live trout, as well as create an overall increase in total swimming activity for live feed days compared to non-live feed days. We also predicted that the penguins would be more likely to use the entire exhibit around these live feeds, since they are likely to chase fish throughout the exhibit. Penguins did show an increase in swimming activity in the hour prior to and during the live feed, with a small decrease in swimming activity following the live feed when compared to non-live feed days. There was also a more than 30% increase in the total swimming activity for live feed days when compared to all other non-live feed days. In addition, a single measure of variability in enclosure use (entropy) showed greater overall enclosure use for the live feed days compared to the non-live feed days. These results demonstrate that live fish can be a useful way of enriching the behavioural welfare of Humboldt penguins.

ABSTRACT This study evaluates a modern natural deposit of Magellanic penguin remains in the coast of the Pampas region, and discusses the regional availability of this resource for prehistoric hunter-gatherer populations, as well as the potential for the natural incorporation of this species into the archaeological record. The penguin assemblage from the surveyed area, which results from beaching during seasonal migration, consists of disarticulated bones, articulated bones, and carcasses. In the skeletal representation, there is a strong predominance of limbs and shoulder girdle elements. Natural processes such as weathering, sedimentary abrasion, and predator action highly affected the preservation of specimens. Even though penguins could have been a potential prey for hunter gatherer populations of the Pampas region, our results suggest that they were not an attractive food resource given their scarcity and poor nutritional condition. The spatial distribution of modern penguin remains and the archaeological evidence suggest that the natural incorporation of bones from this seabird into surface archaeological sites can be expected in the backshore and deflated interdunes. However, the chances of long term burial and bone preservation are low; thus, the formation of a stratigraphic archaeological site containing intrusive penguin remains in these settings is unlikely.
