Haemosporidian infection of the American Kestrel in the southern Chihuahua Desert, Mexico: relationship with land use
We aimed to assess haemosporidian prevalence and parasitaemia in the American Kestrel ( Falco sparverius ) in relation to land use (i.e. small villages...

Ectoparasites exposure affects early growth and mouth colour in nestlings of a cavity-nesting raptor
AbstractNest-dwelling ectoparasites are a major source of stress for growing nestling birds, as they can negatively impact on growth and physiology,...

Reduced ectoparasite load, body mass and blood haemolysis in Eurasian kestrels (Falco tinnunculus) along an urban–rural gradient
Urbanisation is proceeding at an alarming rate which forces wildlife to either retreat from urban areas or cope with novel stressors linked to human...

Seasonal variations in the intermediate metabolism in South American tree-frog Boana pulchella
Seasonal metabolic changes can be observed in many anurans’ species. In subtropical environments with environmental temperatures variations, the...

Seasonal trends in adult apparent survival and reproductive trade-offs reveal potential constraints to earlier nesting in a migratory bird
Birds aim to optimize resources for feeding young and self-maintenance by timing reproduction to coincide with peak food availability. When...

Environmental factors affecting the wintering raptor community in Armenia, Southern Caucasus
The species–habitat relationships can change during the year because of the seasonality of resources. Therefore, the investigation of habitat use by...
