Abstract The Red-footed Falcon is a facultatively colonial species that exploits rookeries, artificial nest-box colonies and solitary corvid nests for breeding. Moreover, the remain gregarious in post breeding period using communal roost sites prior to migration. We developed implemented survey protocol allow precisely estimate number of pairs all three types assess large scale spatio-temporal changes site usage. Our results show lowest (558) was 2006. However, 2014 showed two fold increase,...
Abstract The red‐footed falcon F alco vespertinus is an enigmatic colonial raptor of high international conservation concern. One the identified threatening factors responsible for recent worldwide population decline shortage suitable nesting sites. In theory, this problem can easily be resolved by establishing artificial colonies. However, key to a successful large scale nest‐box scheme provide these colonies in habitats species. A H ungarian– S erbian project aimed establish such...
Abstract Shortage of breeding sites is an important limiting factor bird populations. Artificial platforms, nest-boxes or man-made twig nests often present solutions with remarkable results, however long-term sustainability these populations remains to be resolved. Furthermore, the question whether inference results studies conducted on birds in artificial can generalized other populations, still open. Here we history, and a 20 year old (1995-2015) nest-box programme initiated increase...
Abstract We studied hunting success of 13 male Red-footed Falcons by radio-telemetry in the second phase chick rearing. coded 484 events, and measured captured prey biomass/minute was exceedingly high corn fields. This is mainly caused fact that effectiveness for vertebrate on harvested stubble Moreover observed falcons hunted insects these field alfalfa fields most successfully. In habitat feeding period coincide with harvest cereal fields, suddenly created lower vegetation cover increases...
Avian host species have different roles in the amplification and maintenance of West Nile virus (WNV), therefore identifying key taxa is vital understanding WNV epidemics. Here, we present a comprehensive case study conducted on red-footed falcons, where host-vector, vector-virus host-virus interactions were simultaneously studied to evaluate contribution circulation qualitatively. Mosquitoes trapped inside falcon nest-boxes by method originally developed for capture blackflies midges. We...
Abstract Red-footed Falcons are gregarious trans-equatorial migrants, forming up to several thousand strong roost sites after the breeding season and before commencing migration. This pre-migration period is presumed play a major role in defining survival of long-range migrants. Here we investigate autumn movements 8 individuals caught satellite-tagged within Carpathian Basin. We found that birds may use multiple can be separated by large distances. A single individual’s home range was 88...
Abstract Selecting a suitable breeding habitats and nest-site within are crucial decisions birds have to make. Free ranging solitary Kestrels may use public information derived from leftover pellets prey remnants previous conspecific attempts assess location quality. However, this also indicate potentially higher nestling ectoparasite load. In colonies where habitat quality is similar for all available nests, the only of nest usage reflect expected future parasite pressure. study we explored...
Abstract Active conservation measures often entail supplementing scarce resources, such as food or nesting site to high value species. We hypothesized that adequate nest material in reasonable distance is a resource for Rooks breeding open grassland habitats of Hungary. Here we show willingly utilize large quantities provided excess material, and this procedure may alter composition, increase the number successful pairs. Our results while height remains constant, twig diameter significantly...
Eurasian Woodcock (Scolopax rusticola) plays a special role in the cultural heritage of most nations Europe. In last decade, ringing revealed main migratory patterns some well studied and intensively harvested populations wintering Western Southern The same study sites were focus when recently revolutionized satellite tracking technologies allowed individual migrations. contribution to these efforts, we present here pre-nuptial migration data Woodcocks captured tagged with GPS-Argos...
Abstract Little is known about the louse species harboured by Red-footed and Amur Falcons despite fact that various life-history traits of these hosts make them good model to study host-parasite interactions. We collected lice samples from fully grown (n=20) (n=59), nestlings (n=179) in four countries: Hungary, India, Italy South Africa. identified 3 on both host species, namely Degeeriella rufa, Colpocephalum subzerafae Laembothrion tinnunculi. The latter has never been found hosts....
Abstract Permanent ectoparasites live in stable environments; thus, their population dynamics are mostly adapted to changes the host life cycle. We aimed investigate how static and dynamic traits of red-footed falcons interplay with louse subpopulations during breeding they affect colonisation new hosts by lice. sampled falcon ( Falco vespertinus ) nestlings (two seasons) adults (one season) southern Hungary. The mean abundance Colpocephalum subzerafae Degeeriella rufa lice on was modelled...
Abstract The Eurasian woodcock prefers habitats where its main prey, earthworms, can be found in higher densities. Although they are forest‐dwelling birds, regularly visit pastures and natural grasslands at night, earthworm abundance is generally higher. However, there little information on fine‐scale habitat use relation to variation characteristics prey availability, particularly beyond the breeding season. In our study, we investigated if nocturnal occurrence of woodcocks during migratory...
Abstract Sex-biassed and age-biassed parasite infections are common in nature, including ectoparasites-vertebrate host systems. We investigated the effect of Amur Falcons’ sex, age body size on abundance their lice at a migratory stopover site, where falcons’ habitat use behaviour more homogeneous across sex categories than during breeding season. sampled Falcons Nagaland, India major roosting sites 2016. applied generalized linear models (with negative binomial distribution log-link) to...
Based on the genotyping of 97 chicks and 74 adults from 37 families we describe extra‐pair paternity (EPP), intraspecific brood parasitism (IBP), quasi‐parasitism (QP) polygamy in Red‐footed Falcon Falco vespertinus . The frequency resulting EPP was 2.06% affecting 2.70% (two chicks, one nest), values for IBP were 1.03% offspring families, same detected QP (each chick nest). Altogether, 4.12% 8.11% affected by some alternative reproductive strategies. As far as know, this is first described...
