The Role of Two Tyrosinase‐Like Glycoenzymes in Defining the Final Hue of Parrot Plumage

Pigment Cell &Melanoma Research, Volume 38, Issue 3, May 2025.
ABSTRACT Recent advances in avian melanogenesis have pinpointed multiple genetic loci associated with color polymorphisms, predominantly in the plumage of chickens, quails, and pigeons. However, the genetic basis of melaninization in parrot plumage remains elusive.

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

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.

野生动物学报, 1991
大绯胸鹦鹉（Psittacula derbiana）在动物园中俗称“四川鹦鹉”,野生时通常在树洞里筑巢、产卵和孵化。动物园饲养时一般设置树洞、木箱、缸管等作为繁殖巢,而我园饲养的大绯胸鹦鹉则以隐蔽处的砂堆为巢产卵及孵化,其中1989年有一对大绯胸鹦鹉繁殖两只幼鸟全部成活。现将繁殖情况总结如下: 一、生活环境自1988年以来,我园饲养的8只大绯胸鹦鹉（7雌1雄）与1只挂线鹦鹉（Psittacula krameri）、7只亚利山大鹦鹉生活在同一笼舍中,笼舍的地面面积为13.05平方米,舍高2.4米 ...

Genomic Introgression Between Critically Endangered and Stable Species of Darwin's Tree Finches on the Galapagos Islands

Evolutionary Applications, Volume 18, Issue 1, January 2025.
ABSTRACT Natural hybridisation among rare or endangered species and stable congenerics is increasingly topical for the conservation of species‐level diversity under anthropogenic impacts. Evidence for beneficial genes being introgressed into or selected for in hybrids raises concurrent questions about its evolutionary significance.
