Estimated and in vivo measurements of bite force demonstrate exceptionally large bite forces in parrots (Psittaciformes)

Journal of Anatomy, Volume 246, Issue 2, Page 299-315, February 2025.
Bite force in parrots has been explored using data from muscle masses. The values were validated by comparison with data for bite force collected from live parrots. The parrot's reputation for a strong bite force is well founded. Abstract Jaw morphology and function determine the range of dietary items that an organism can consume.

BREEDING STATUS AND NEST CHARACTERISTICS OF ROSERINGED (PSITTACULA KRAMERI) AND ALEXANDRINE PARAKEETS (PSITTACULA EUPATRIA) IN ISTANBUL’S CITY PARKS

Applied Ecology and Environmental Research, 2019
Invasive non-native parakeet populations are increasing throughout Europe with proved negative impact on native fauna and Turkey is no exception. Rose-ringed and Alexandrine parakeets have established populations in Turkey's large cities but even basic distribution, abundance and breeding behaviour information is missing. This study aims at determining
