Full textIn 1996, caching behaviour of 10 single females, 10 single males and 20 paired captive American kestrels was recorded over the breeding season at the Avian Science and Conservation Centre of McGill University.
Cache site preference and seasonal influence on caching frequencies were studied in 8 hand-raised, male kestrels in summer, fall and winter from 1996--1997. Caching frequency during the three seasons was significantly different with most occurring in fall, fewer in winter, and still fewer in summer.
Memory for locations of cached prey was tested in 7 hand-raised males, three days after a caching event, from July to September 1997. The birds located their own caches significantly better than those caches placed by the experimenter. (Abstract shortened by UMI.)

Full textKnowing the habitat preference of a species is of crucial importance in order to sketch measures with conservational purposes. In this study we analyse the foraging habitat preferences of a threatened species and how they change through the breeding season. Habitat availability varies due to changes in agricultural activities such as ploughing, sowing, or harvesting. Our results evidence that this species select different habitat types according to breeding season stage. In the beginning of the season prefer to forage in ploughed fields while during chick rearing and post-fledging prefer cotton fields and cereal stubbles. Thus changes in agricultural activities must be considered in habitat selection studies. Lesser kestrels prefer to forage in low height and sparse cover, probably because of higher prey availability in this kind of habitats. Males and females don’t show significant differences in several hunting parameters. Success rate was higher in cereal stubble and during incubation and lower in ploughed fields and in the pre-incubation period. Lesser kestrels take less time to make a strike in cereal stubble and more in cotton plantations. In cereals prey capture takes less time while in cotton takes more hunting effort. The number of strikes per minute of observation didn’t varied significantly between habitats.

Apesar da radiotelemetria ser considerada uma ferramenta valiosa em estudos ornitológicos, algumas teorias relativas ao impacto de radiotransmissores sobre a estimativa de parâmetros comportamentais, ecológicos e reprodutivos podem ser encontradas em literatura. Com o intuito de avaliar os potenciais efeitos fisiológicos de radiotransmissores do tipo mochila em falcões quiri-quiri (Falco sparverius) de vida livre, oito machos desta espécie foram capturados e divididos em dois grupos: indivíduos marcados com radiotransmissores (aproximadamente 5% do peso vivo, n = 6) e indivíduos controle (anilhados, n = 2). Em seguida, amostras fecais foram coletadas duas horas após a captura (dia −1) e durante os dias 0 (definido como o dia de soltura dos animais), 4, 7, 15, 30, 40 e 55. Previamente às análises laboratoriais, o ensaio imunoenzimático para dosagem de glucocorticóides fecais foi testado empregando procedimentos padrões de validação hormonal (paralelismo, curva de dose-resposta, validação fisiológica e coeficientes de variação inter- e intra-ensaio). Em relação aos machos monitorados, ambos os grupos apresentaram um aumento significativo nos níveis de glucocorticóides fecais durante o dia 0 (P < 0,001), mas as concentrações retornaram aos níveis pré-equipagem após 4 dias da soltura. Além disso, os níveis de glucocorticóides fecais não diferiram significativamente entre os falcões radiomarcados e os anilhados durante os 55 dias de monitoramento (P > 0,05). Embora o número de indivíduos neste estudo seja reduzido, estes resultados sugerem que radiotransmissores do tipo mochila não induzem efeitos persistentes sobre a atividade adrenal de machos de falcões quiri-quiri de vida livre. Considerando a literatura consultada, esta é a primeira pesquisa a analisar os efeitos de radiotransmissores sobre a resposta adrecortical de aves de vida livre.
Although radiotelemetry is considered a valuable technique for ornithological field studies, several assumptions have been made about the impact that transmitters may cause on the estimation of behavioral, ecological and reproductive parameters. To assess potential effects of backpack radiotransmitters, we captured and assigned 8 male American kestrels (Falco sparverius) in 2 groups: radio-tagged (n = 6) and control individuals (leg-banded, n = 2). Thereafter, we collected feces two hr after capture (day −1), and subsequently during days 0 (releasing day), 1, 4, 7, 15, 30, 40 and 55. Prior to fecal analysis, EIA corticosterone assay was validated using standard procedures (e.g. parallelism, dose-response curve), and physiological significance of fecal glucocorticoid metabolites was confirmed through adrenocorticotropin (ACTH) challenge, which induce an increase of 4-fold (446.10 ± 60.73 ng/ g) above baseline (114.27 ± 15.23 ng/ g) within 4 hr (P < 0.001). Both groups exhibited a significant increase in fecal glucocorticoids during day 0 (P < 0.001), but concentrations returned to pre-attachment values within 4 days. Fecal glucocorticoid concentrations did not differ between samples of radio-tagged and leg-banded kestrels (P > 0.05). In spite of the small number of monitored subjects, these findings suggested that radiotransmitters did not affect adrenocortical activity in male American kestrel. To our knowledge, this is the first research to evaluate the effects of transmitters on stress responses in free-ranging birds.

Full textUma apreciação correcta e atempada da pressão intraocular (PIO) é crítica para a avaliação de alterações oculares como o glaucoma e uveíte. Na prática clínica esta é realizada recorrendo à sua medição indirecta através da tonometria. No entanto, para que esta tenha valor diagnóstico, o clínico necessita conhecer os valores normais de PIO das espécies examinadas. Neste estudo foi realizada a tonometria de aplanamento com recurso ao Tono-Pen VET® (Reichert Technologies, 230635V, Nova Iorque, E.U.A.), para estimar a PIO em 40 Peneireiros das torres (Falco naumanni) e 12 Peneireiros comuns (Falco tinnunculus), animais residentes no Grupo de Rehabilitación de la Fauna Autóctona y su Hábitat (GREFA) em Madrid, Espanha. Antes da tonometria foi realizado um exame físico e oftalmológico completo a todas as aves, garantindo o seu estado hígido para integração neste estudo. As medições tonométricas foram realizadas após a aplicação de uma gota de anestésico tópico (hidrocloreto de oxibuprocaína e hidrocleto de tetracaína, Colircusi Anestesico Doble®, Laboratórios Alcon, Barcelona, Espanha) na superfície corneana dos animais. A média (± DP) de PIO no Peneireiro das torres foi de 11,4 ± 2,7 mmHg (68 olhos) e de 13,9 ± 3,5 mmHg (22 olhos) no Peneireiro comum. Não se encontraram efeitos significativos na mesma entre sexos, idades, olho direito e esquerdo e o número da medição para ambas as espécies. Foram encontradas diferenças significativas entre espécies (teste de duas amostras de Wilcoxon, P=0,017). Alguns aspectos inerentes à técnica tonométrica foram ainda avaliados, em relação aos quais, se verificou que a temperatura do ambiente em que se efectuaram as medições tonométricas tinha efeito na PIO, o qual foi significativo (teste de duas amostras de Wilcoxon, P=0,047). Sugere-se ainda, que a realização de medições pode beneficiar da crescente experiência do utilizador no manuseamento do tonómetro. Em geral, a tonometria de aplanamento demonstrou ser um método diagnóstico da PIO com aplicabilidade e facilidade de utilização bem como, apresentou um boa aceitação por parte das aves de rapina abordadas. No entanto, ao não existir um instrumento ideal para cada animal, é uma técnica que deve considerar a variabilidade existente entre espécies, indivíduos e utilizadores.
ABSTRACT - TONOMETRY IN BIRDS OF PREY – ASPECTS OF ITS APPLICATION IN THE CLINICAL PRACTICE - An accurate and early assessment of intraocular pressure (IOP) is essential for evaluating ocular disorders such as glaucoma and uveitis. In the clinical practice this is accomplished by its indirect measure through tonometry. Nevertheless, for it to be of diagnostic value the clinician must know the normal values of the examined species. In this study applanation tonometry was performed using the Tono-Pen VET® (Reichert Technologies, 230635V, New York, U.S.A.), to estimate IOP in 40 Lesser kestrels (Falco naumanni) and 12 Common kestrels (Falco tinnunculus), resident animals of the Grupo de Rehabilitación de la Fauna Autóctona y su Hábitat (GREFA), in Madrid, Spain. Before the tonometry, a complete physical and ophthalmological examination was carried out in all birds ensuring their healthy state for inclusion in this study. Tonometric measurements were performed after application of one drop of topical anesthetic (oxybuprocaine hydrochloride and tetracaine hydrochloride, Colircusi Anestesico Doble®, Alcon Laboratories, Barcelona, Spain) on the animals’ corneal surface. Mean (± SD) IOP in the Lesser kestrel was 11,4 ± 2,7 mmHg (68 eyes) and 13,9 ± 3,5 mmHg (22 eyes) in the Common kestrel. There were no significant effects between sex, age, right and left eye or reading number on the IOP measured in any of the species. Significant differences were found between species (Two-sample Wilcoxon, P=0,017). Some inherent aspects to the tonometry technique were also evaluated, for which it was found that the environment temperature in which the measurements took place had a significant effect on the IOP (Two-sample Wilcoxon, P=0,047). It is also suggested that the performance of measurements can benefit from the growing user experience in handling the tonometer. In general, applanation tonometry has proven to be an IOP diagnostic method with great application, easy use and showing a good acceptance by the bird of prey patient. However, since there isn’t an ideal instrument for each animal, it is a technique that must consider the variability among species, individuals and users.

Full textDen globala uppvärmningen påverkar Arktis klimat vilket orsakar en snabbt föränderlig miljö för den Arktiska biotan. Effekten av klimatförändringarna är ökade väder variationer och extremer. Pilgrimsfalken är en väl studerad toppredator men få studier har undersökt hur extremt väder påverkar pilgrimsfalkens häckningsframgång i arktiska miljöer. Därför undersöker vi förhållandet mellan extrema väder och häckningsframgången för pilgrimsfalken på södra Grönland. Vi har i denna studie använt data om pilgrimsfalkens häckningsframgång på södra Grönland som sträcker sig från år 1981 och fram till 2015. Väderdata som använts för att kalkylera variablerna: extrem temperatur, extremt regn, regndagar i följd och totalt antal dagar med extremt väder har erhållits från två väderstationer inom studieområdet. Häckningssäsongen analyserades i sin helhet samt delades in i perioderna: “innan äggläggnings-”, “ruvnings-” och “ungar-i-boet-perioden”, vilka korrelerades mot vädervariablerna. Vi fann att dagar med extremt väder påverkar pilgrimsfalkens häckningsframgång negativt under hela säsongen samt under perioderna “innan äggläggning” och “ruvning”. Extrema väderhändelser kan alltså förklara variationer i häckningsframgången för pilgrimsfalken på södra Grönland. Resultatet indikerar även att andra faktorer påverkar häckningsframgången då det finns en stark nedåtgående trend i pilgrimsfalkens häckningsframgång men inte en ökning av extrema väderhändelser under samma period.

O bulbo do olho é uma parte do organismo pouco estudada e que carece de mais valores fisiológicos nas diversas espécies de animais. Neste sentido, o objetivo deste trabalho foi avaliar os cortes histológicos dos olhos de Falco tinnunculus (peneireiro-de-dorso-malhado), por meio da morfometria da córnea, retina, coróide e esclera. As aves eram adultas e de vida livre. Os resultados obtidos foram comparados entre machos e fêmeas e entre os olhos direito e esquerdo. Após enucleação dos olhos, os mesmos foram fixados em solução tamponada de formaldeído por 48 horas e posteriormente, descalcificados. Os olhos direitos foram cortados verticalmente (dorsoventral), e os esquerdos horizontalmente (temporonasal). Após inclusão em parafina, foram confeccionados cortes de 5m de espessura e corados pelas técnicas rotineiras de hematoxilina e eosina. Para a análise dos cortes, foram definidos e medidos, seis pontos (1 a 6) na retina, coróide e esclera, e três pontos referentes na córnea (A, B e C).

Full textThe present study concentrates on two methods for diagnosing birds of prey with aspergillosis with the intent to increase the knowledge of the validity of these non-invasive diagnostic methods. In the first study, specific radiographic signs of digitally created radiographs of falcons (Falco spp.) which were exclusively positive for aspergillosis (n = 110) were systematically analyzed and compared to the typical radiographic signs of parrots with diseases of the lower respiratory tract. In the second study, healthy falcons (n = 73) and falcons affected with aspergillosis (n = 32) (Falco spp.) were examined by using serum protein electrophoresis in order to create reference values for healthy falcons and compare them with the values of the affected falcons. In both studies, the animals were patients of the same clinic. While evaluating the radiographs of the falcons with aspergillosis, mainly subtle radiographic signs were described. Radiographically within normal limits were 29 (26.4%) of the 110 animals. The most commonly reported findings were inhomogeneous increased radiodensity of the lung area (38.2% laterolateral [ll]), line-shaped shadowings of the caudal lung border (II 30.0%) as well as an inhomogeneous (34.5% ll, 29.1% ventrodorsal [vd]) and streaky (26.4% II) radiodensity of the air sacs, but also a poor delineation of the cardiac silhouette in the laterolateral projection (42.7%). Compared to studies performed on parrots by conventional radiography, the portion of subtle radiographic signs was lower and the portion of severe signs was higher. Compared to reference values of various raptor species from the literature, this study, which made use of the high-resolution electrophoresis SAS 1 unit (Helena, Saint Leu La Forest, France), revealed relatively low values for total proteins and relatively high values for prealbumin in the reference values of the healthy falcons. The 32 serum samples of the falcons suffering from aspergillosis showed a significantly reduced total albumin (albumin + prealbumin) level and a highly significantly reduced prealbumin level compared to the 73 serum samples of healthy falcons. Although the falcons were for the most part already brought to the clinic in one of the early stages of the disease, when diagnosing aspergillosis is particularly difficult, both examination methods revealed different results for the healthy and diseased animals. However, the findings related to aspergillosis were in some cases significantly different from those described in the literature as the \"typical\" findings in birds suffering from aspergillosis. This can be explained by the fact that most of the comparable studies were conducted with parrots held as pets or with captive zoo birds (when husbandry, anatomy and physiology, as well as performance level are different from falcons) and with a different technique (digital versus conventional radiography, different electrophoresis systems and the use of serum instead of plasma). The digital radiography can be fully recommended for specialized medical institutions for avian medicine as well as for small animal practitioners because of its easy, rapid and gentle feasibility. To date, the protein electrophoresis can only be recommended with restrictions for practitioners, however for specialized institutions, it can be useful as additional diagnostic tool if all its specific features are taken into account

Full textIV Les ignifugeants bromés sont des polluants organiques tenaces, répandus globalement dans l'environnement. Lipophiles et bioaccumulatifs, on les retrouve dans les tissus animaux, dont ceux des rapaces qui possèdent parmi les concentrations les plus élevées. Cette étude avait comme objectif global de déterminer les effets sur la reproduction, le comportement et la physiologie de crécerelles d'Amérique (Falco sparverius) captives exposées à deux ignifugeants brominés d'importance, soit les polybromodiphényléther (PBDE : mélange DE-71) et l'hexabromocyclodécane (HBCD), à des concentrations représentatives des niveaux environnementaux. En 2007, trois groupes de mâles exposés in ovo à des concentrations moyennes (± l'erreur-type) de DE- 71 respectives de 288,60 ± 33,35 ng/g mh (faible exposition), de 1130,59 ± 95,34 ng/g mh (forte exposition) et de 3,01 ± 0,46 ng/g mh (contrôle), ont été accouplés avec des femelles non-exposées, et euthanasiés l'année suivante pour en extraire les testicules. En 2008, des couples furent exposés au HBCD dans leur alimentation quotidienne, soit à une concentration de 0.544 µg/µl mh ou à un niveau-contrôle. De plus, la masse et l'histologie testiculaires de mâles non-accouplés exposés pendant trois semaines à ces mêmes concentrations respectives furent analysées. Comparés aux couples-contrôle, les couples avec mâles exposés au DE-71 ont subi une réduction dans la grandeur de leurs couvées et dans la masse et la fertilité de leurs œufs, ainsi qu'un délai dans leur ponte. Chacun des membres de ces couples démontra une diminution des comportements nuptiaux, dont la fréquence de copulation, et les mâles ont fait preuve de soins parentaux réduits. Ces derniers avaient également des testicules hypertrophiés contenant un plus grand nombre de tubules séminifères pourvus de lumen, cependant le nombre de tubules contenant des spermatides finales décrut en fonction de la croissance du niveau d'exposition à certains congénères PBDE. De leur part, les couples exposés au HBCD ont connu des pontes précoces comportant un plus grand nombre moyen d'œufs que les couples-contrôle, par contre leur succès reproductif global demeura inchangé. Bien que l'épaisseur des coquilles ne fut pas affectée, leurs œufs étaient anormalement petits et légers. Encore une fois, chacun des membres de ces couples démontra une baisse dans les comportements nuptiaux et l'apport de soins parentaux fut réduit chez les mâles. Ces derniers présentèrent également à certains moments des niveaux de testostérone et des masses corporelles supérieurs ainsi que des niveaux de thyroxine (T4) inférieurs aux mâles-contrôle, et les mâles non-accouplés développèrent de plus gros testicules avec plus grand nombre de tubules séminifères contenant des spermatides finales. L'ensemble de ces résultats démontre que les deux ignifugeants bromés en question, à leurs niveaux environnementaux, agissent effectivement sur la reproduction chez les crécerelles d'Amérique. Il est donc admissible de supposer que les crécerelles à l'état sauvage, voire même autres oiseaux, éprouvent des impacts comparables.

Full textA study of the ecology of the Southern African Kestrel was made in two areas of differing topography in the Eastern Cape Province (32 °S) of South Africa. The main objectives of the study were to describe foraging parameters (behaviour-time budgets, hunting success and diet) and breeding parameters (clutch size, hatching and fledging success, nestling, fledging and post-fledging periods) of the Southern African Kestrel. These parameters were compared to those from studies made on the European Kestrel (Falco tinnunculus tinnunculus) in western Europe (53 °N) in an environment which fluctuates relatively more than the South African study sites. Predictions concerning foraging and breeding ecology made by life-history theory in stable and fluctuating environments prompted the erection of the following hypotheses which were examined in this study. 1. Common Kestrels (Falco tinnunculus) in relatively stable environments have a more consistent but lower foraging yield than those breeding in fluctuating environments. 2. Common Kestrels in relatively stable environments have lower reproductive rates (longer incubation, nestling and post-fledgling dependence periods, later age at first breeding and longer life-span) than those in fluctuating environments. Southern African Kestrels spent different proportions of time of the two main hunting methods used, perch- and hover-hunting, than the European Kestrel. Perch-hunting was the predominant hunting method used by the Southern African Kestrel compared to hover-hunting in the European Kestrel. Southern African Kestrels had a higher prey-capture success for both hunting techniques. However, daily food intake was lower in Southern African Kestrels because a high proportion of the diet consisted of small invertebrates. Average clutch size was smaller in the Southern African Kestrel than that of the European Kestrel and Southern African Kestrels fledged on average fewer young. However, incubation, nestling and post-fledging periods were within the range recorded for the European Kestrel. The hypothesis that Common Kestrels in relatively stable environments have lower foraging yields is supported by this study. Although results from this study suggest that food yields are more consistent in stable environments, it was unable to evaluate this adequately. The hypothesis that reproductive rates are lower in relatively stable environments is partly supported in this study, but more data are required for parameters such as incubation and nestling periods to confirm such trends.
