Captive fledgling American kestrels prefer to play with objects resembling natural prey
Article Abstract:
Many young predators use object play to develop skills in manipulating live prey. To test whether fledgling raptors discriminate between actual prey and surrogate objects during object play, several fledgling American kestrels were separately given mouse mimics and surrogate objects. Results showed that fledglings given both mimics and surrogate objects played longer and more frequently than those given surrogate objects. The results suggest that young raptors devote a fixed amount of time to object play and prefer to play with objects resembling play. Adult kestrels did not play with any of the play objects.

Feeding chases and food allocation in Adelie penguins, Pygoscelis adeliae
Article Abstract:
Research undertaken among Adelie penguins at the Northern Colony at Cape Bird, Ross Island, Antarctica, indicates that feeding chases are a means by which parent penguins can reduce interactions between chicks. Feeding chases balance out the impact of size asymmetries caused by sibling competition. Parent penguins are more likely to run away when they have two chicks begging from them than when they have only one. They are also more likely to run away when the chicks are closer to them than further away.

The function of feeding chases in the chinstrap penguin, Pygoscelis antartica
Article Abstract:
Feeding chases in chinstrap penguins helps parent penguins supply food according to the size and needs of the chicks. Chicks chase parent penguinsbefore they are fed and results of a study indicate that this helps parents to regulate the supply of food to their off-springs. The study also found that chicks that chase more actively get more food. Significant differences betwwen the nature of chasing was observed in single chick and multiple chick families.
