A Revised and Improved Version of the Northern Wheatear (Oenanthe oenanthe) Transcriptome

Oenanthe incrassans: An enigmatic species from Turkey and its comparison with Oenanthe pimpinelloides (Apiaceae)

Oenanthe incrassans (Apiaceae) was discovered in Istanbul, Turkey. It is related to Oenanthe pimpinelloides, but it clearly differs in terms of leaves, inflorescence (ray, bracts, and bracteoles) and fruit features. A taxonomic description, some photographs of the species, geographical distribution and habitat features are given. Additionally, fruit micromorphology, stem, ray and fruit anatomy,...

Morphological Shifts of the External Flight Apparatus across the Range of a Passerine (Northern Wheatear) with Diverging Migratory Behaviour

We studied morphological differentiation in the flight apparatus of the four currently recognised sub-species of Northern Wheatears, Oenanthe oenanthe. Considering all measured birds without assigning them a priori to any sub-species we found a clinal morphological shift. Relative wing length, wing pointedness, and the degree of tail forking were positively correlated with migratory distance, w...

Innate Sex Differences in the Timing of Spring Migration in a Songbird

In migrating animals protandry is the phenomenon whereby males of a species arrive at the breeding grounds earlier than females. In the present study we investigated the proximate causes of protandry in a migratory songbird, the northern wheatear Oenanthe oenanthe. Previous experiments with caged birds revealed that males and females show differentiated photoperiod-induced migratory habits. How...

COLOURATION AND BIOMETRY OF THE BLACK-EARED WHEATEAR Oenanthe hispanica FROM THE EASTERN ADRIATIC COAST Obojenost i biometrija istočnojadranske populacije primorske bjeloguze Oenante hispanica

Museum skins of the Black-eared Wheatear Oenante hispanica from the eastern Adriatic coast were examined in order to identify subspecies. All 91 examined skins belong to O. h. melanoleuca. Wing lengths (88-96 mm in adult males, 87-93.5 mm in 2nd year males and 84-92 mm in females) are among the longest for this species. The proportion of the black-throated morph was 56.5% in males and 40.9% in ...
