Recent development in video monitoring has allowed collecting of data on prey deliveries at raptor nests, and this offers an opportunity to relate prey selection to short-term changes in environmental factors on a scale of hours. Whereas raptors may specialize on ectothermic prey at southern latitudes, only some generalist raptors may include such prey in their diet at northern latitudes. In particular, at northern latitudes the activity pattern of ectothermic reptiles is strongly dependent on… Expand

Prey delivery and diet of the Eurasian kestrel (Falco tinnunculus) in a peak year of the wood lemming (Myopus schisticolor)
TLDR
Video monitoring to study diet and prey delivery rate of six breeding pairs of the Eurasian kestrel in Trysil, south eastern Norway, during the breeding season 2011 suggested that wood lemmings are caught only when the abundance of wood lemming is high and the abundanceof Microtus voles is low.

Diet and prey handling at a nest of the golden eagle (Aquila chrysaetos) in Oppland County, Norway
The diet and prey handling of a breeding pair of the golden eagle (Aquila chrysaetos) in Oppland County, Norway, was analysed with video monitoring of prey deliveries at the nest during the ten weeksExpand
Do males pay more? A male-biased predation of common lizard (Zootoca vivipara) by great grey shrike (Lanius excubitor)
TLDR
It is suggested that in this particular predator-prey system, shrikes may be a strong selective force for lizards’ population dynamics and male-biased predation could be caused by differences in the behaviour of adult male and female lizards, namely longer activity of males and differences in space and refuge use. Expand
Parents adjust feeding effort in relation to nestling age in the Eurasian Kestrel (Falco tinnunculus)
TLDR
The decrease in provisioning rate during the later nestling stages was best explained by nestling age, and it cannot be conclusive as to whether this was caused by a decrease in nestling food demand, or by a seasonal decrease in the availability of voles, the dominant prey. Expand
Evolution of parental roles in raptors: prey type determines role asymmetry in the Eurasian kestrel
TLDR
To investigate the poorly understood evolution of role asymmetry in raptors at an intraspecific level, videorecorded prey delivery and handling in 25 nests of the Eurasian kestrel, with prey types ranging in size from insects via lizards and mammals to birds, and simultaneously observed prey transfer from male to female outside the nest. Expand
Prey Delivery Rates as Estimates of Prey Consumption by Eurasian Kestrel Falco tinnunculus Nestlings
TLDR
It is argued that kestrels in the boreal forest would be unable to raise an average brood solely on insects or lizards, but able to do so solely on voles in a vole peak year. Expand
The conservation and landscape genetics of the sand lizard Lacerta agilis
TLDR
Sand lizards from across the Britain were genotyped at 15 microsatellite loci and the resulting dataset used to address questions regarding the conservation genetics, phylogeography and influence of landscape on patterns of genetic diversity. Expand
Activity Budgets, Foraging Behavior, and Diet of White-Tailed Kites (Elanus leucurus) During Breeding and Nonbreeding Seasons In the Argentine Pampas
TLDR
In the Argentine Pampas, White-tailed Kites are predominantly mammal-eating, active-search predators, as previously reported for the species in South America and North America and for other Elanus species around the world. Expand
STELLAGAMA STELLIO DAANI (BEUTLER & FRÖR, 1980) AS A PREY OF FALCO TINNUNCULUS LINNAEUS, 1758 ON TILOS ISLAND (DODECANESE, AEGEAN SEA)
The aim of this work is to provide some notes on the biology and feeding habits of the common kestrel Falco tinnunculus Linnaeus, 1758 on Tilos Island (Dodecanese, Greece). The discovery of manyExpand
Predators as mediators: Differential antipredator behavior in competitive lizard species in a multi-predator environment
TLDR
Differences in antipredator response in two competing lizards in syntopy in a multi-predator environment are studied to shape the relationships between both species in syntopic populations modulated by common predation pressure and habitat structure. Expand

How does the European common lizard, Lacerta vivipara, survive the cold of winter?
TLDR
Differential scanning calorimetry conducted during the hibernation period showed that the blood of highland lizards had an increased ability to resist ice formation, confirming an ecophysiological effect most likely mediated by physical properties of the blood. Expand
Prey Size Selection of Insular Lizards by Two Sympatric Predatory Bird Species
TLDR
Considering lizard availability, shrikes displayed less selective predation than kestrels in all seasons, and kestRELs appeared to be more selective, negatively choosing the small lizard size but positively selecting the largest ones all the year round. Expand

A comparison of the diet of the Common Kestrel Falco tinnunculus in South Africa and Europe
TLDR
The diet of the Southern African Kestrel Falco tinnunculus rupicolus was studied in both a flat and a hilly area in the eastern Cape Province, South Africa, where the main component of the diet consisted of arthropods, primarily Orthoptera and Arachnida, while the few vertebrates eaten included birds and lizards.

Predation on reptiles and birds by the common buzzard, Buteo buteo, in relation to changes in its main prey, voles
It has commonly been assumed that predators whose main prey are voles reduce their predation on other prey when voles are abundant. This assumption may, however, not be valid for slow-moving andExpand
The feeding constraint hypothesis: prey preparation as a function of nestling age and prey mass in the Eurasian kestrel
TLDR
It is suggested that the extent to which kestrel parents decapitate prey prior to delivery is an effect of their nestlings’ age-dependent swallowing capacity and that the age of the nestlings therefore imposes constraints on the kestrell parents’ foraging behaviour. Expand
Consistent differences in feeding habits between neighbouring breeding kestrels
TLDR
The presence of differences in diet composition between neighbouring pairs and their temporal consistency suggests that the hunting skills, and in general the feeding behaviour of kestrels, is likely to represent a trait characterising a behavioural type. Expand
Weather-dependent foraging success and sibling aggression in red-tailed hawks in central Washington
TLDR
Observations on weather-dependent delivery of prey by Red-tailed Hawks to unfledged young and on sibling aggression at a nest in central Washington are consistent with the hypothesis that food availability affects the number of healthy young the parents are capable of rearing. Expand
