Abstract:

Research on nest occupation and prey grabbing by saker falcon (Falco cherrug) on power lines in Vojvodina (Serbia) was done in the period from 1986 to 2004. During three specially analyzed periods, saker falcon took the nests of raven (Corvus corax) in 91% of a total of 22 cases of nest occupation, and those of hooded crow (Corvus corone cornix) in only 9%. Saker falcon regularly grabs prey from different birds that occasionally or constantly spend time around power lines [Kestrel (Falco tinnunculus), hobby (Falco subbuteo), hooded crow (Corvus corone cornix), jack-daw (Corvus monedula), marsh harrier (Circus aeruginosus), hen harrier (Circus cyaneus), buzzard (Buteo buteo), and raven (Corvus corax)]. One year a studied pair of saker falcons on a power line in Donji Srem, Serbia grabbed prey from five different species of birds. Out of a total of 40 cases of prey grabbing in the period from January to December, as much 70% of the grabbed prey was taken from kestrel (Falco tinnunculus). During the winter and early spring, prey was grabbed predominantly by males; after May, prey was sometimes grabbed by females as well. Most of the grabbed prey was common vole (Microtus arvalis).

Abstract:

Pododermatitis (bumblefoot) is a major health problem of falcons worldwide because healing processes in the talons are difficult and lengthy. A peregrine (Falco peregrinus), a merlin (Falco columbarius) and a saker falcon (Falco cherrug) with bumblefoot at different stages ranging from III to V, were all found to be carriers of micrococcus-like organisms in the blood and two of them were successfully treated with 0.5% potassium arsenite in low dosage given intravenously. A number of considerations are made on the immune dysfunction aspects of bumblefoot in birds of prey and on the emerging role of arsenic-based medicaments in the treatment of animal and human immune dysfunction syndromes.

Abstract:

O intenso fluxo de animais do Neotrópico observado na Europa durante o início da Idade Moderna incluiria demandas muito singulares vindas de determinados atores sociais. Este parece ser exatamente o caso das aves de rapina, em geral destinadas a uma nobreza entusiasta da falcoaria que concentrava desmedido poder e se mostrava disposta a oferecer atrativas recompensas por exemplares trazidos do além-mar. Vigente ao menos desde 1509, esse tráfico abarcava tanto representantes dos Accipitridae quanto dos Falconidade, havendo registros documentais ou iconográficos para o japacanim (Spizaetus ornatus), o falcão-peregrino (Falco peregrinus) e o falcão-de-coleira (Falco femoralis) – provavelmente o misterioso "aleto" pelo qual se pagavam quantias exorbitantes. A documentação disponível também menciona a surpreendente captura de um gerifalte (Falco rusticolus) ao largo da costa do Brasil – a primeira referência conhecida dessa espécie para o hemisfério sul. Tal como foi comprovado para vários outros grupos zoológicos no continente americano, os dados existentes sugerem a forte possibilidade de algumas rapineiras neotropicais terem sido bem mais numerosas no período colonial.

Abstract:

I analyse recent trends in the status and distribution of breeding birds of prey in the Canary Islands (Spain). Populations of Barbary Falcon Falco peregrinus pelegrinoides, Eleonora's Falcon Falco eleonorae, Sparrowhawk Accipiter nisus granti, Buzzard Buteo buteo insularum and Osprey Pandion haliaetus recovered throughout the 1990s. Egyptian Vulture Neophron percnopterus majorensis continues to be seriously threatened, with a total population of only around 130 birds. There is a lack of information on status of nocturnal birds of prey, especially of the Canary subspecies of Barn Owl Tyto alba gracilirostris, whose numbers seem to have decreased. Genetic studies should be carried out to clarify the taxonomic status of the birds of prey of the Canary Islands.

Abstract:

The objective of this pilot study was to evaluate the feasibility of Flash Visual Evoked Potentials (FVEPs) testing in birds of prey in a clinical setting and to describe the protocol and the baseline data for normal vision in this species. FVEP recordings were obtained from 6 normal adult birds of prey: n. 2 Harris’s Hawks (Parabuteo unicinctus), n. 1 Lanner Falcon (Falco biarmicus), n. 2 Gyrfalcons (Falco rusticolus) and n. 1 Saker Falcon (Falco cherrug). Before carrying out VEP tests, all animals underwent neurologic and ophthalmic routine examination. Waveforms were analysed to identify reproducible peaks from random variation of baseline. At least three positive and negative peaks were highlighted in all tracks with elevated repeatability. Measurements consisted of the absolute and relative latencies of these peaks (P1, N1, P2, N2, P3, and N3) and their peak-to-peak amplitudes. Both the peak latency and wave morphology achieved from normal animals were similar to those obtained previously in other animal species. This test can be easily and safely performed in a clinical setting in birds of prey and could be useful for an objective assessment of visual function.

Abstract:

The diet of the American Kestrel (Falco sparverius) and Aplomado Falcon (Falco femoralis) was quantified by analysis of their pellets during the summer 1997-1998 in an agricultural area of Araucanía, southern Chile. By number, the most important prey of the American Kestrel were insects (61% of all individual prey) followed by birds (23%), rodents (13.7%) and reptiles (2.6%). Avian prey accounted for the highest biomass contribution (79.6%), followed by rodents (18%). Biomass contribution of insects and reptiles was negligible. Birds were the staple prey of the Aplomado Falcon both by number (89%) and biomass (99%). Number and biomass contribution of rodent and insect prey was minute. Diet of both raptor species did not broadly overlap. Both the American Kestrel and Aplomado Falcon appeared to respond in an opportunistic manner to the most abundant bird prey in the field (Sicalis luteola), although the latter species could be consuming preferentially larger-sized avian prey.

Abstract:

Abstract Eleonora's Falcon (Falco eleonorae) breeds in the Mediterranean region and is highly adapted for catching small birds on passage migration between Eurasia and their African winter quarters, which they feed their young. We studied gliding flight behavior of Eleonora's Falcon at a breeding colony located on a small island southwest of Sardinia, Italy. Gliding and soaring flight performance was measured using an optical range finder and evaluated against flight mechanical theory. The male falcon does the majority of hunting and usually sets off from the colony to hunting areas located at high altitude over the open sea to catch prey. To lower the cost of transport and maximize the energy gain from hunting, we show that the birds use vertical winds for soaring when available. The occurrence of rising air changes with wind direction. At north-northwesterly winds (on-shore), slope lift is available outside the nesting cliffs, and at south-southeasterly winds thermals that form over the island drift out over the sea. Our observations demonstrated the flexibility of flight behavior in relation to the wind situation, and birds thereby make full use of available soaring conditions.

Abstract:

We describe and discuss a field observation of a strongly speckle-breasted and barred Black Falcon Falco subniger that also, unusually, had yellow feet and cere and pale-yellow orbital rings. We also found several museum specimens with ‘variegated’ plumage and yellow bare parts. We speculate that yellow bare parts in this species might occur only in some individuals, perhaps mostly males, of the most variegated (pale-marked) plumage types, and that these correlated features may be age-related characters that deserve further investigation. We also discuss the implications for field identification.

Abstract:

From 1999 to 2020 the Eleonora’s Falcon (Falco eleonorae) has been observed 12 times at the site of Madonna del Pino, near Demonte (Province of Cuneo - Piedmont - South Western Alps). All of these individuals were birds in their second calendar year and thus these sightings are to be attributed to summer movements of nonbreeding animals. The growing number of observations of this species is imputable to the increasing identification skills of birdwatchers, necessary in order to distinguish Eleonora’s Falcons from the similar and very common Eurasian Hobby (Falco subbuteo), and to the constant monitoring of migrating raptors as part of the Migrans Project.

Abstract:

Abstract The red-footed falcon and Eurasian falcon represent two syntopical falcon species. While the Eurasian falcon is considered a common and numerous species in Slovakia, the red-footed falcon population has undergone a considerable decline during the past few decades. Nowadays it nests in a single locality in Slovakia, the Sysľovské polia Special Protection Area, which forms the northern and fragmented border of the species distribution area in Europe. By analysing prey remains from 9 nests (from 1998, 2001, 2013, 2014 and 2016), we identified 433 prey items belonging to 35 taxa and 9 orders. Every year, invertebrates made up the major part of the diet spectrum, in which Calosoma auropunctatum, Tettigonia viridissima, Zabrus tenebrioides, Anisoplia aegetum and Rhizotrogus sp. were the most frequent species of prey. Of the vertebrates, Microtus arvalis was the most hunted prey species. By supplementary analysis of 21 photos, we extended our knowledge on the diet by other 6 taxa. The peak of the M. arvalis population growth in 2014 did not manifest itself in the red-footed falcon diet composition. In 1998, 2014 and 2016 we also studied the diet of a syntopical species, the Eurasian kestrel. By analysing prey remains in 22 nests, we identified 1,151 prey items belonging to 37 taxa and 7 orders. In 1998 and 2014 vertebrates predominated, especially the common vole, however in 2016 invertebrates prevailed. This fact could be a reaction to the M. arvalis population peak in 2014 and its decline in 2016. These results suggest that this variability in the foraging behaviour of the Eurasian kestrel, an opportunistic predator, during the hunting of invertebrates increases the diet similarity and overlapping of the food niche of both studied falcon species.

Abstract:

Abstract Ectoparasite fauna of Falco vespertinus breeding colonies was investigated in a system of artificial nests in the Po valley (Parma province), Italy, during four subsequent breeding seasons (2019–2022). Conservation actions regarding Falco vespertinus led to a great increase in its presence in the area. This rise was believed to coincide with an increase in the prevalence of hematophagous ectoparasites breeding in the nests, with a potential negative impact on the attractiveness of the breeding site. Ectoparasites collected from the nestlings’ bodies almost entirely belonged to a single species, Diptera Carnus hemapterus, with a quite variable prevalence in different years. Maximum ectoparasite load was consistently linked to younger than two weeks old chicks. Carnus hemapterus may pose a threat to less resilient specimens of Falco vespertinus because it feeds on live tissues, increases metabolic expenditure, and can introduce blood parasites. Nonetheless, this species is part of the ecosystem shared with the falcon and might have a conservational value itself. We propose that higher occurrence of this ectoparasite might be linked to diet parameters, especially the availability of small mammals and the lingering of prey remnants in the nests, as well as to the age of the parasitized nestlings. These findings might have important implications for the conservation of this rare Falco species.

Abstract:

Abstract The Saker Falcon is a falconid raptor species with Palearctic distribution. It has never been a common bird in Hungary, now there are cc. 220-230 nesting pairs within the country borders. Currently total world population is cc. 19 000-34 000 individuals. Its taxonomic status is complicated. Two subspecies are distinguished (Falco c. cherrug and Falco c. milvipes); however, molecular data does not support this split. Phylogeny of the species is also not clarified, similarly to closely related raptors. There are many factors threatening the population of the Saker. One of these factors is the occurrence of the hybrid falcons. By molecular investigations more data can be gained, that could be useful in practical conservation, too.

Abstract A peregrine falcon (Falco peregrinus) was observed preying on a mallard (Anas platyrhynchos) in Hokkaido, northern Japan, before dawn. The observation was made on 13 January 2013 about 40 minutes before sunrise, in the dark. Although there were sparse street lamps and car traffic nearby the observation point, it is not as evenly and continuously well-lit as urban areas. This suggests the potential of peregrine falcon to forage successfully in non-urban habitat under low light conditions.

Full text

Abstract:

A clear understanding of a species’ diet is crucial in understanding its spatio-temporal dynamics, and is, therefore, pertinent to conservation considerations. The diet of the Grey Falcon (Falco hypoleucos), a rare and threatened predator endemic to the Australian arid and semi-arid zone, is subject to diverging assertions; therefore, we studied its diet through direct observation of food ingestion during more than 17 years of fieldwork across the species’ distribution. We found that Grey Falcons of all ages fed almost exclusively on a single type of food, namely, birds, and non-avian food items never constituted a substantial portion of any individual’s diet. The extraordinary circumstances that were associated with the ingestion of non-avian food suggest strongly that, across its vast distribution, throughout the year, and throughout its life, the Grey Falcon feeds almost exclusively on birds. Further, we compared the diets of all Falco species and found that the dietary specialization is most extreme in the Grey Falcon, more so than even in the Taita (F. fasciinucha) and Peregrine Falcons (F. peregrinus). Based on aspects of the species’ environment and relative prey availability, we offer an evolutionary explanation of the apparently unique dietary specialization of the arid-adapted Grey Falcon.

AbstractWe collected prey remains from 25 Peregrine Falcon (Falco peregrinus) territories across Arizona from 1977 to 1988 yielding 58 eyrie-years of data. Along with 793 individual birds (107 species and six additional genera), we found seven mammals and nine insects. In addition, two nestling peregrines were consumed. We found a larger dependence upon White-throated Swifts (Aeronautes saxatalis) and birds on migration in northern Arizona, while in southeastern and central Arizona average prey mass was greater and columbiforms formed the largest dietary component. In northern, central, and southeastern Arizona, 74, 66, and 56 avian prey taxa, respectively, were recorded. We used capture-recapture modeling to estimate totals of 111 ± 9.5, 113 ± 10.5, and 86 ± 7.9 (SE) avian taxa taken in these same three areas. These values are counterintuitive inasmuch as the southeast has the richest avifauna. For the entire study area, 156 ± 9.3 avian taxa were estimated to be taken by peregrines.Dieta Estival de Falco peregrinus en Arizona Comparando Zonas Ricas y Pobres en Avifauna Mediante un Modelo de Captura-RecapturaResumen. Desde 1977 a 1988 colectamos restos de presas en 58 nidos de Falco peregrinus a través de Arizona. Conjuntamente con 793 aves individuales (107 especies y seis géneros adicionales), encontramos siete mamíferos y nueve insectos. Además, fueron consumidos dos pichones de Falco peregrinus. En la zona norte encontramos una mayor dependencia sobre Aeronautes saxatalis y aves en migración, mientras que en las zonas sureste y central la masa promedio de presa fue más grande y los columbiformes constituyeron el componente principal de la dieta de Falco peregrinus. En las zonas norte, central y sureste se registraron 74, 66 y 56 taxa de aves presa, respectivamente. Para estimar el número total de taxa capturados por Falco peregrinus usamos un modelo de captura-recaptura. Los valores calculados fueron 111 ± 9.5, 113 ± 10.5 y 86 ± 7.9 (EE) taxa para las zonas norte, central y sureste, respectivamente. Estos valores no reflejan los que esperábamos, ya que la zona sureste tuvo una avifauna más rica. Se estimó que 156 ± 9.3 taxa fueron capturados por Falco peregrinus en la totalidad del área de estudio.

Abstract:

AbstractTe objective of this study was to investigate aspects of the nesting biology of the Aplomado Falcon, Falco femoralis (Temminck, 1822), at Parque Nacional das Emas, Brazil. Woodland (Campo Cerrado) frebreaks were searched for nests in October 2006 and October 2009 by driving a vehicle along a road adjacent to these fre managed vegetation strips. Most (62%) of the eight nests found were in canopies of fruiting Pouteria torta trees. Nests were at 2.2–3.8 m above ground. Invariably, clutch size was of three cream eggs and nestlings had a white plumage in the frst days of life. For two active nests, adults also defended an additional empty nest located in the surroundings. No evidences of nest destruction or predation were detected. Falco femoralis successfully uses frebreaks for breeding at Parque Nacional das Emas.

Abstract:

The eye is one of the most important sensory systems in the body because of its importance and it plays an important role in communication between animals and their environment. In recent study collect ten eye of falcon and ten eye of owl from Najaf desert during April 2020 to March 2021. By using Hematoxylin and Eosin staining (H&E) have been obtained sections of retina of falcon (Falco columbarius) and owl (Bubo bubo) which consist of ten layers, we measured thickness of three layers for both birds and have got differences between them. Falcon has less thickness layers from owl but there are different in retinal ganglion layers, in falcon which have surface area more than owl. That’s depended to nature of life which falcon and owl have. Keywords: retina, retinal layers, falcon and owl.

Abstract:

Among birds, falcons are high-performance flyers, in many cases adapted for aerial hunting and hence suitable targets for investigating limits to flight performance. Using an optical range finder, we measured flight tracks of Eleonora's falcon (Falco eleonorae), a species breeding in the Mediterranean region and specialised for hunting autumn passage bird migrants, when commuting between their nesting colony and offshore hunting areas (straight transportation flight) and when searching for prey (transecting and searching flight). Airspeed during searching flight was significantly slower than during straight transportation and transecting flight, but there was no significant difference in airspeed between the latter two flight modes. Straight transportation flight was significantly faster than predicted minimum power speed. Also, during straight transportation flight, the falcons responded to head- and tailwinds by increasing their airspeed when flying into the wind. However, they did not show any significant airspeed adjustments with respect to the angle between the track and the heading, as would be expected in birds trying to maintain a constant track direction. Mean sustainable climb rate (during (greater than or equal to) 240 s) was 1.4+/−0.31 m s-1 (mean +/− s.d., N=13), which is rather a high rate for a bird the size of an Eleonora's falcon. The climb rate was used to calculate maximum load-carrying capacity and maximum sustained horizontal flapping flight speed. The mean wingbeat frequency during powered climbing flight was 4.68 Hz, which was used to estimate the mass-specific muscle work. When falcons were leaving the colony for offshore hunting, they gained altitude by slope-soaring when there was an onshore wind. We formulated a simple criterion for the required gliding-flight rate of climb during an initial slope-soaring episode when minimizing the energy cost of reaching a certain altitude far out over the sea (which is where the prey is to be found). This climb rate was 0.36 m s-1, and our observations indicated that the falcons experienced climb rates above this value when soaring in slope-lift.
