Effect of photoperiod on the adrenal activities of male rose ringed parakeet, Psittacala krameri.
Adult male rose ringed parakeets were exposed to very long photoperiod (22 hr L: 2 hr D) and very short photoperiod (2 hr L: 22 hr D) daily for 60 days during different phases of the annual testicular cycle. Adrenal activities of the experimental birds were compared with that of parallel held natural photoperiodic birds. Marked atrophy of adrenocortical cells was noted in the glands of long pho...
متن کاملAlien invasive birds.
A bird species is regarded as alien invasive if it has been introduced, intentionally or accidentally, to a location where it did not previously occur naturally, becomes capable of establishing a breeding population without further intervention by humans, spreads and becomes a pest affecting the environment, the local biodiversity, the economy and/or society, including human health.

Dolenec, Z.: Intraspecific nest parasitism in the starling (Sturnus vulgaris) in northwestern Croatia. Nat. Croat., Vol. 10, No. 4., 315–320, 2001, Zagreb. This study reports intraspecific nest parasitism in starlings (Sturnus vulgaris) in the village of Mokrice, northwestern Croatia, in 1999 and 2000. Twenty one (30.5%) out of 70 observed nests during the two years contained one or two parasit...
متن کاملResource Use by Non-Native Ring-Necked Parakeets (Psittacula krameri) and Native Starlings (Sturnus vulgaris) in Central Europe
In general, non-native bird species may competitively exclude native species from nest sites. The potential resource conflict between a native and an introduced bird species, the native European Starling (Sturnus vulgaris) and the introduced Asian Ring-necked Parakeet (Psittacula krameri), was inferred from hole occupancy in parks of the German Upper Rhine Valley (Wiesbaden, Mannheim, Schwetzin...
متن کاملNestling Development of Ring-necked Parakeets (Psittacula krameri) in a Nest Box Population
Chick development of a population of non-native Ring-necked Parakeets (Psittacula krameri) (RNP) has been investigated between 2006 and 2008 in Heidelberg, Germany. In parrots hatching asynchrony is common. RNP chicks are under natural selection to fledge synchronously with their siblings, as parents return less often to the nest after the first chick has fledged and remaining chicks may starve...
