The Wake of a Kestrel (Falco Tinnunculus) in Gliding Flight

Skin carotenoid concentration correlates with male hunting skill and territory quality in the kestrel Falco tinnunculus

In the context of sexual selection carotenoid based signals are candidates for indicator traits: they have to be taken up in the diet by animals, they can indicate the ability of the bearer to accumulate a limited resource, and they help in maintaining the health status. We investigated the yellow-orange colouration of the tarsi of the kestrel Falco tinnunculus in relation to sex, diet and to d...

Blood Cell Morphology, Some Hematological and Serum Biochemistry Values of Common Kestrel (Falco tinnunculus)

In this study, morphological characteristics of peripheral blood cell, and certain hematological and serum biochemistry values were determined in 16 clinical healthy adult common kestrels in order to establish normal reference values for this population. Seven different types of blood cells were determined, such as erythrocytes, thrombocytes, big lymphocytes, monocytes, heterophils, basophils, ...

Winter predation by Common Kestrel Falco tinnunculus on Pipistrelle Bats Pipistrellus pipistrellus in Southern Spain

Methionine supplementation influences melanin-based plumage colouration in Eurasian kestrel, Falco tinnunculus, nestlings.

The extent to which the expression of melanin-based plumage colouration in birds is genetically or environmentally determined is controversial. Here, we performed a between-nest design supplementation with either the sulphur amino acid dl-methionine or with water to investigate the importance of the non-genetic component of melanin-based plumage colouration in the Eurasian kestrel, Falco tinnun...
