Content available remote People, birds, canoes, and seafaring in the Pacific islands:
100%
EN
Birds around the Pacific are identified with human activities, and often with people themselves. This article explores the pervasive use of birds and avian imagery by Pacific islanders in legend, song, canoe construction, and navigation. It considers a preoccupation with birds in diverse spheres of island life, but with special attention to maritime activities.

The objective of this study was accomplishes a knowledge survey of the Mura indigenous on the birds of natural occurrence in their territory, who is located in the Amazonas State, Brazilian Amazon Rainforest. As method for collect the data were used open and semi-structured interviews. Twenty four indigenous were interviewed, with both genres and different ages. The interviewees mentioned 118 different species of birds, counting about 60% of the records, which in addition to the interviews was completed by surveying the bird by direct field observations with sighting and vocalization in different natural environments of the indigenous territory. The indigenous showed wide ecological knowledge regarding these birds. The oral transmission of knowledge occurs across generations.

The diversity of birds is directly correlated with the structure of the forest. Any interfering with the vegetation produces direct effects on the avifauna through the increase, decrease, or alternation of two key attributes: food and shelter. Thus, the composition of life in the forest is altered as changes occur in vegetation that directly interferes with the population structure of the avifauna, be those changes natural or anthropic. This study was realized in fragments of the Amazon Rainforest, and the main objective was to analyze the behavior of frugivorous and omnivorous birds in three different stages of ecological succession. In forest environments where a vertical stratification of resources occurs, these species are distributed occupying a in a high diversity of trophic niches. The diversity and density of the frugivorous and omnivorous birds in the forest fragments in medium and advanced stage of ecological succession could be directly correlated not only with the structure of the forest, but also to the fact that these birds feed almost exclusively on abundant and easy to find food sources - shrub and tree fruit of certain vegetable species that are naturally abundant in the rainforest understory layer.

Content available Michael Longley and Birds
100%
EN
The following essay attempts to shed some light on Michael Longley’s poems about birds, which form a fairly complicated network of mutual enhancements and cross-references. Some of them are purely descriptive lyrics. Such poems are likely to have the name of a given species or a specific individual representative of that species in the title. Others make references to birds or use them for their own agenda, which often transcends the parameters of pure description. Sometimes birds perform an evocative function (“Snow Geese”), prompt the poet to explore the murky mysteries of iniquity (“The Goose”), judge human affairs from the avian vantage (“Aftermath”), or raise ecological problems (“Kestrel”). Most of the time, however, Longley is careful not to intrude upon their baffling otherness. Many of his bird poems are suffused with an aura of subtle yet suggestive eroticism, a conflation of the avian and the amorous.

Objectives: To evaluate the risk factors for the development of occupational allergy to birds among Polish zoo garden keepers. Methods: A total of 200 bird zookeepers employed in the Polish zoo gardens in Łódź, Warsaw, Gdańsk, Chorzów and Płock and exposed occupationally to bird allergens were examined using a questionnaire, skin prick tests (SPTs) to common allergens and bird allergens, spirometry and cytograms of nasal swab. The level of total IgE in serum and serum-specific IgE to parrot, canary, pigeon feathers and serum were also evaluated. Results: Eight percent of bird zookeepers were sensitized to at least one of the bird allergens. The most frequent allergens yielding positive SPT results were D. farinae - 32 cases (16%), D. pteronyssinus - 30 cases (15%) and grass pollens (16.5%). In the studied group, allergen-specific IgE against bird allergens occurred with the following frequency: 87 (43.5%) against canary feathers and/or serum, 80 (40%) against parrot feathers and/or serum and 82 (41%) against pigeon feathers and/or serum. Occupational allergy was diagnosed in 39 (26.5%) cases, occupational rhinitis was present in 22 (15%) cases, occupational asthma in 20 (13.6%) subjects, occupational conjunctivitis in 18 (12.2%) cases, whereas occupational skin diseases in 11 (7.5%) cases. More eosinophils were found in nose swab cytograms among bird zookeepers with occupational airway allergy. Conclusions: The findings indicate that occupational allergy to birds is an important health problem among zoo bird keepers in Poland.

The main purpose of this article is to draw attention to one of the motifs which appear regularly in literature concerning the Nazi concentration camps. In many memoirs of ex-convicts the concentration camp is represented as a place „where birds did not sing” – an area domed by an empty, silent sky, „a sky without birds”. The author of this paper examines this phenomenon from many perspectives, drawing on various types of sources. The voices of the imprisoned are surprisingly juxtaposed with ornithological research conducted by Günther Niethammer, a scientist and, simultaneously, one of the SS guards in the Auschwitz concentration camp. This article is part of ever-growing contemporary research on the topoi of concentration camp literature and Holocaust literature. Ecocriticism and environmentalism constitute an important inspiration for his text, and a post-anthropocentric perspective allows the author to extend the scope of historicity to include the non-human beings, such as animals, plants and the landscape.

The aim of the article is to indicate a recurring motif in the writings devoted to Nazi concentration camps. In many of the accounts of male and female internees the camp was described as a place “where birds did not sing”. As a territory over which there spun an empty silent sky. “A Birdless Sky”. The author of the study, utilising various sources, attempted to study the phenomenon from different perspectives. The results of scientific ornithological studies conducted by Günther Niethammer, a scientist and an SS guard at KL Auschwitz proved a rather unexpected point of reference for the voices of the internees. The presented article refers to the increasingly lively contemporary research into the topics of Lager and Holocaust literatures. Ecocriticism and environmentalism have been some of the more significant inspirations of the proposed discussion. By introducing a post-anthropocentric perspective, the author was able to expand the historical field to include non-human beings (animals, plants, landscapes).

Superstitions have their origins at the beginning of human civilization and makeup part of the very essence of human intellect. Indigenous peoples, due to their ethnic diversity, contributed in different ways with many cultural aspects. Religious beliefs and superstitions play an important role within Indigenous culture. The objective of this study was to accomplish a survey of the superstitions of some Indigenous peoples of the Amazon about certain species of birds. The method for collecting the data was used open and semi-structured interviews with Indigenous people from the Arara, Tenharim, Kayabi, and Apiaká ethnic groups.

This article is about a short story entitled Wilga (The Oriole) (1925). This work was written shortly before the writer’s death and is his elegiac farewell to his home in Konstancin, an expression of love to his daughter Monica and a kind of his literary summary and a testament. An important part of the discussion is focused on how the writer used his own autobiography in his artistic works and how he is relying on his memory while creating the literary image. This article also focuses on ornithological knowledge of the writer which is an important fact that has not been given enough attention in relation to Żeromski’s works. It was reconstructed on the basis of his Diaries, Memoirs and literary works. The presented findings can serve as an aid in developing a monograph on the birds themes in the works of the author of The Labors of Sisyphus.

Gołębie dziobią sobie spokojnie rozrzucone okruchy, nieświadome tego, jak wielkie grozi im niebezpieczeństwo. Z „gołębiego” dziada pradziada czuły się niemal bezpieczne w mieście – obawiały się jedynie samochodów i kotów. Teraz atak przychodzi z powietrza. Atak niebywale szybki.

The objective of this study accomplished a knowledge survey of the Bororo indigenous on the birds of natural occurrence in their territory, Meruri village, who is located in the Mato Grosso State, Brazil, in the Savannah biome, and also the relationship of the indigenous with these birds. As the method for collect, the data were used open and semi-structured interviews. Twenty-two indigenous were interviewed, both genres and different ages. The interviewees mentioned 96 species of birds and they showed wide ecological knowledge regarding these birds. Such relationships are complex, being evidenced by a mythical interaction between the man and the elements of nature. These birds are important elements in the creation of stories, legends, in the Bororo ceremonies and arts. The oral transmission of knowledge occurs across generations.

Darwinian theory of sexual selection and its development up to the present state of knowledge are sketched. The most important results of empirical studies on sexual selection in the Swallow Hirundo rustica are reviewed. The Swallow is a socially monogamous, slightly sexually dimorphic avian species. Long tail streamers are considered as sexual ornaments of males. Female preference for long and symmetric male tails has been inferred on both observational and experimental grounds. Experimental elongation of the tail causes short-term benefits and long-term costs in male reproductive performance. Behavioural consequences of sexual selection acting in the Swallow are discussed. An aerodynamic role of male tail streamers is also considered.

Zagrożenia środowiskowe dla lotnictwa to przede wszystkim kolizje statków powietrznych z ptakami. Wiele państw zrzeszonych w ICAO, w tym Polska, współpracuje ze sobą w ramach WBA (World Birdstrike Organization). Ostatnia Konferencja ICAO/WBA/CARSAMPAF była efektywnym forum wymiany informacji i wspólnej analizy zaleceń, wymagań zawartych w dokumentach IGAO, FAA oraz EASA. Dla zwiększenia efektywności zarządzania ryzykiem środowiskowym niezbędne są standaryzacja oceny ryzyka kolizji z ptakami oraz regularne i zróżnicowane szkolenia dla personelu lotnisk. Olbrzymia większość kolizji z ptakami ma miejsce na lotnisku i w jego najbliższym otoczeniu. Procedury minimalizowania ryzyka obejmują przede wszystkim działania proaktywne (zarządzanie siedliskami) oraz reaktywne (przepłaszanie ptaków), powinny być one częścią systemu zarządzania bezpieczeństwie (SMS). Działania te wymagają także zaangażowania m.in. pilotów, kontrolerów ruchu, władzy lotniczej, linii lotniczych, biologów oraz organów mających wpływ na zarządzanie otoczeniem lotnisk. Bardzo ważne jest również dostosowanie działań minimalizujących ryzyko kolizji ze zwierzętami do regulacji dotyczących ochrony środowiska, gdyż prawie wszystkie gatunki ptaków podlegają ścisłej ochronie w Polsce. Największe i najważniejsze dla bezpieczeństwa lotnictwa gatunki ptaków obejmują swoim zasięgiem olbrzymie obszary kontynentów, współpraca w ramach regionalnych organizacji, w tym WBA-Europe, jest niezbędne dla efektywniejszych działań minimalizujących zagrożenia. W Polsce powyższymi zagadnieniami zajmuje się Komitet ds. zderzeń statków powietrznych ze zwierzętami, który analizuje zagrożenia, proponuje zmiany w zapisach prawnych oraz działania wspomagające lotniska cywilne i wojskowe w minimalizowaniu ryzyka kolizji.

Wildlife hazard for aviation concerns mostly bird strike risk to aircrafts. The last ICAO/ WBA/CARSAMPAF meeting was very effective concerning information exchange and analyzing of regulation and recommendations of ICAO, FAA, EASA documents. Standardization of bird strike risk assessment and annual training program for the aerodrome personnel are essential for effective wildlife hazard management plan (WHMP). Majority of bird strike occurs on or in close vicinity of an aerodrome. WHMP should be a part of SMS and cover mostly proactive (habitats management) and reactive (birds harassment) procedures. The cooperation with pilots, ATC, regulators, airlines, biologists is essential for wildlife risk mitigation. Almost all birds species are strictly protected in Poland therefore adjustment for nature protection regulation in WHMP is very important. The most important birds for aviation safety are widely distributed on vast areas, thus international cooperation (like WBA-Europe) within larger areas is essential for effective wildlife risk mitigation. Polish Wildlife Strike Committee is dealing with the wildlife hazard management issues.

Content available Wpływ hałasu drogowego na ptaki
75%
PL
Szybki rozwój sieci drogowej oraz infrastruktury z nią związanej wywiera silną presję na środowisko oraz żywe organizmy, wykorzystujące siedliska zlokalizowane w pobliżu dróg. Negatywne skutki tego procesu polegają na utracie i fragmentacji siedlisk użytkowanych przez zwierzęta. Osobnym zagadnieniem jest wzrost zanieczyszczeń powietrza i gleby w sąsiedztwie szlaków komunikacyjnych. Ważnym problemem jest oddziaływanie hałasu na zwierzęta egzystujące w pobliżu dróg, w tym szczególnie na ptaki. Hałas generowany przez pojazdy zakłóca komunikację dźwiękową ptaków zwłaszcza w okresie formowania się par i wczesnej inkubacji jaj. Zasadnicze funkcje śpiewu ptaków to sygnalizacja rywalom własnego gatunku zajęcia terytorium oraz co najważniejsze przywabienie partnera. Hałaśliwe „tło” w sąsiedztwie drogi powoduje trudności w porozumiewaniu się osobników. Ogólnie zjawisko zakłócania komunikacji głosowej pomiędzy osobnikami przez hałas drogowy, wywołuje tzw. „maskowanie” ważnych sygnałów biologicznych. Najbardziej wrażliwe na wpływ hałasu drogowego okazują się gatunki wydające dźwięki o niskim paśmie częstotliwości ze względu na skuteczność ich maskowania przez hałas charakteryzujący się podobnym spektrum częstotliwości. W efekcie działania hałasu drogowego powstają zmiany w natężeniu a nawet częstotliwości śpiewu ptaków. Niektórzy autorzy zwracają również uwagę na modyfikujący wpływ czynników klimatycznych oraz struktury i typu siedliska w rozprzestrzenianiu się hałasu. Większość wykonanych dotychczas badań dotyczy okresu lęgowego, a tylko nieliczne prace zajmują się oddziaływaniem hałasu na ptaki w okresie migracji lub w okresie zimowania. Najczęściej podejmowanym zagadnieniem przez badaczy jest ocena zagęszczeń lęgowych ptaków przy drodze. W większości badań zaobserwowano spadek liczebności i bogactwa gatunkowego osobników w sąsiedztwie szlaków komunikacyjnych. Jednak niektóre gatunki ptaków, ze względu na tzw. „efekt krawędzi”, który modyfikuje zasobność bazy pokarmowej oraz mikroklimat, występują w większych zagęszczeniach właśnie przy drogach. Ważnym zagadnieniem jest również modyfikujący wpływ hałasu na drapieżnictwo przy drogach.

The dynamic development of road infrastructure negatively influences the natural environment and animals using habitats near roads. The main negative effects of this process are primarily: loss and fragmentation of habitats. Another problem is an increase in pollutants and noise intensity in the vicinity of roads. An important problem is negative influence of traffic noise on animals and especially birds. Road noise generate by vehicles disturb vocal communication between birds, mainly in the time of pair formation and early incubation period. Difficulties in communication evoked by noise seem to be one of the main problems in functioning in noisy surroundings. The main functions of birds’ singing are related with territorial defence and mating a partner. Another important effect on birds’ functioning near roads results in the masking of important biological signals due to noise . Masking important signals for territorial defence or partner selection can have as a consequence a negative influence on reproductive success. Species of birds which emit low frequency sounds are particularly exposed to this negative impact. As a results of traffic noise the changes in the volume and frequency of emitted sounds during singing are observed. Some authors pay attention to such factors as local climate or habitat and vegetation structure, because they have an important influence on the propagation of traffic noise. Most of the studies carried out previously concerns the breeding season, and only a few works to describe the impact of noise on birds during migration or wintering. The most frequently reported problem for researchers is to assess the densities of breeding birds near the roadside. The majority of species react with a drop in numbers at roadsides. There are species which are also known to appear with higher density at roadsides. Usually this is related with a richer plant vegetation structure at roadsides and the appearance of the so-called “edge effect”. Some results indicate that bird density at forest peripheries can reach values 40% higher than in the deep forest. An explanation of causes for such a state of matters are the higher numbers of invertebrates found at forest edges. The important factor influencing bird populations breeding at roadsides is also nest predation. Noise and visual disturbance can modifying predator pressure near roads.
