...Paweł Brzęk; Krista M. Lessner; Enrique Caviedes-Vidal; William H. Karasov SUMMARY It can be hypothesized that species with a wide or variable food niche are able to adjust their digestive physiology to current food type. In diet specialists, however, the capacity for such presumably costly...

Interestingly, this difference was in the same direction as the difference in locomotor activity, possibly suggesting a functional link between the intensity of sibling competition and the digestive physiology of the nestlings. The validity of our conclusions related...
