Acta Ornithologica (AO) zostały założone w 1933 r., pod nazwą Acta Ornithologica Musei Zoologici Polonici. Było to wtedy pierwsze pismo ornitologiczne w Polsce i jedno z pierwszych w tej części Europy. Od tamtych czasów w ciągu 70 lat AO zachowały, z przerwą (1939-1948) spowodowaną wojną, kontynuację jako czasopismo redagowane i wydawane w tej samej instytucji działającej początkowo pod nazwą Państwowego Muzeum Zoologicznego, a obecnie jest to Muzeum i Instytut Zoologii Polskiej Akademii Nauk. AO w całej swojej historii były głównym polskim czasopismem ornitologicznym, zyskując również stopniowo charakter międzynarodowy. W 2003 r. AO osiągnęły status czasopisma objętego wykazem Current Contents filadelfijskiego Instytutu Informacji Naukowej (Institute for Scientific Information, Thomson Scientific). W ciągu 70 lat istnienia AO można wyróżnić sześć okresów, w czasie których czasopismo było tworzone przez różne zespoły redakcyjne (Tab. 1, Appendix 1), kształtujące jego formę i treść stosownie do aktualnych potrzeb naukowych i warunków działania. Ogólna liczba prac opublikowanych w rozpatrywanym czasie wydawania AO wyniosła 614. Średnia liczba prac wydawanych rocznie wzrosła od 6 (1933-1939) do 25 (1999-2003), gdy AO osiągnęły pełną regularność edycji. Do lat 1980., a szczególnie w latach 1949-1973, najczęstszym językiem publikacji był polski (Tab. 1). Później stopniowo znaczenia nabierał angielski, który od 1993 r. stał wyłącznym (z polskimi streszczeniami) językiem publikacji w AO. Do lat 1990s prace o tematyce faunistycznej miały w AO dominujący udział, liczne były też prace dotyczące wędrówek (Tab. 2). Od tego okresu wzrósł udział prac o tematyce ekologicznej oraz dotyczących ochrony i zagrożeń awifauny. Opublikowano też szereg zbiorów tematycznych i konferencyjnych (Appendix 2). Udział prac zagranicznych autorów który wynosił do lat 1990. kilka procent (Tab. 3), wzrósł w okresie 1999-2003 do 21% (+ 9% prac współautorów zagranicznych). Dotychczas prace oparte na materiale zagranicznym stanowiły w różnych okresach 6%-26%, natomiast ostatnio (1999-2003) ich udział wyniósł połowę (Tab. 4). W obu tych porównaniach (Tab. 3 i 4) pominięto publikacje zawarte w zbiorach materiałów z międzynarodowych konferencji. W dystrybucji AO ponad połowę stanowią (2003) odbiorcy zagraniczni z 53 krajów.

During the years 1991-2000,101 bird species were recorded in the city of La Plata, Argentina, 47 of which were breeding ones. The most abundant species were: Zenaida auriculata, Columba livia, Funarius rufus, Pitangus sul- phuratus, Zonotrichia capensis and Passer domesticus. Columba maculosa, C. picazuro, Fumarius rufus, Turdus rufiventris and Molothrus bonariensis have increased in number, while Passer domesticus has decreased. Zonotrichia capensis may successfully compete for food with Passer domesticus. Sturnus vulgaris and Acridotheres cristatellus are new species in the breeding avifauna of La Plata city.

During a four-year study of the breeding biology and ecology of an atypical population of Barn Swallows nesting in 13 abandoned post-war bomb shelters, the unexpected presence of foreign juveniles in active nests with nestlings was recorded on eight occasions. In five cases, single birds were noted, and in the other three, two foreign individuals were observed. The average age of the nestlings joined by foreign juveniles was 11.6 days (SE = 1.08, range 8-16), while the average age of the latter birds recorded with the nestlings was 23.2 ± 1.02 days (range 20-25). The mean distance between the hatching and parasitised nests was 0.9 ± 0.11 m (range 0.5-1.2). This unusual behaviour in swallows seems to be deliberate and is aimed at choosing a nest with nestlings in order to obtain extra food from experienced adult birds rather than an error caused by the darkness in the shelter.

In addition to the well-known limiting effect of cavity abundance on the density of hole-nesting passerines, other aspects of cavity availability may shape their communities as well. Notably, where there is a considerable aggregation of cavities, territory-holders may prevent the occupation of the nearest cavities by other birds, whereas a supply of diverse cavities may reduce interspecific competition. We used multivariate general linear models to explore whether, and how, variables describing the supply of small cavities are related to the density and diversity of hole-nest- ing passerine communities in 33 hemiboreal old forest stands. The total density of 12 species (1.3 ± 0.8 pairs/ha) increased with cavity density and diversity, but was not affected by cavity aggregation. As expected, cavity diversity also promoted bird diversity; indeed, the densities of different species were positively related to the densities of different cavity types. The results indicate that segregation in nest-cavity selection affects the co-occurrence of passerine species and, at the mean densities of small tree-cavities in the region (2.3/ha), cavity aggregation does not markedly reduce their availability. In conservation management, therefore, it is important to maintain a diverse supply of cavities in addition to their abundance, in order to sustain hole-nester communities.

The Blue Chaffinch is a passerine endemic to the Canary Islands and comprises two subspecies, one found on Tenerife (Fringilla teydea teydea) and the other on Gran Canaria (F. t. polatzeki). Even though the status of the Gran Canaria subspecies is endangered due to habitat loss and fragmentation, knowledge of its life history is anecdotal. We studied its breeding ecology during the years 1991-2004. New data are presented on breeding phenology, number of broods per year, egg biometrics, nest-site characteristics, breeding site fidelity and breeding success. In general, the breeding biology of the two subspecies were similar, with discrepancies in some previously reported traits, such as egg laying interval and frequency of second clutches. The Blue Chaffinch breeds earlier on Gran Canaria than on Tenerife: nests were begun mainly in the second fortnight of May. We did not find any relationship between the onset of egg laying and rainfall in March. However, the onset of the breeding period was negatively correlated with mean April temperature. The Blue Chaffinch showed preferences for a south-easterly nest orientation and for nest placement at the end of branches, where the nest is hidden by pine needles. Nests were located at various heights, from 5.5 to 23.8 m above the ground. 33% of females produced two broods a year. We found no differences in nest site characteristics between successful and unsuccessful nests, which suggests that other factors may be affecting the vulnerability of nests. The main cause of nesting failure (73.9%) was predation, due mostly to the Great Spotted Woodpecker.

Studies carried out in the vicinity of Rogów in central Poland showed a 47% rise in the population density of the Common Buzzard, inasmuch as the average number of breeding pairs in the study area of 105 km² increased from 18.2 in the years 1982-1991 to 26.7 in the years 2001-2003. Furthermore, an upward trend was observed for each separately investigated forest complex. Possible mechanisms underpinning this increase in density are discussed.

During seven winter seasons (1993/1994-1999/2000) 107 roadside counts (28 km each) in agricultural area of south-western Poland were conducted. From among 1526 Buzzards, 1293 were recorded in winter months (November-February) and 233 in March. Birds were non-randomly distributed on nine vegetation types met along the transect route. Permanent papilionaceous crops, along with cereal stubbles, margin habitats, meadows and maize stubbles were preferentially used, whereas bare tillage and winter cereals were avoided. In general, Buzzards preferred habitats of the least amount in the studied area and avoided those which dominated. These data support the idea of high importance of small landscape structures for the biodiversity protection in intensively used farmland. During winter months, most Buzzards (59.5%) were perched when first sighted, most often on trees and in the middle part of their height. The percent of birds sitting on the ground amounted to 34.7%. The smallest amount of individuals (5.8%) was observed flying (flap-sailing, hovering and soaring), however this activity significantly increased in March (up to 17.1%). The significance of various hunting methods for wintering Buzzards is discussed. Even though it is a typical perch hunting raptor, the method of hunting from the ground seems to be particularly suitable for the conditions of winter farmland: common scarcity of perches, poor and low vegetation, local and temporary prey concentrations.

In the Water Rail the patterns of the two main types of vocalization were quite different: the announcement call was uttered throughout the breeding season with two peaks, one in April and the other in early June, but the courtship call occurred only in the pre-laying period. The vocalization period of the Little Crake is short but intensive, peaking before the start of incubation. In general, Water Rails produced more vocalizations in the evening than in the morning. The vocal activity of the Little Crake peaked at dawn. In both species a peak in vocal output occurred shortly before sunrise and before sunset.

The first stage of the Siberian Knot's autumn migration between its breeding grounds in Taimyr, Siberia and the W European tidal flats is still poorly understood, despite our expanding knowledge of this species. This paper analyses data (1988-1995) on the numbers of Knots and the timing of their migration in the Puck Bay region of the Baltic Sea (N Poland). The timing varied greatly between seasons. The timing of adult migration is linked to breeding success. In seasons with low breeding success both males and females leave the breeding grounds earlier, and the correlation between the mean date of adult migration and the number of juveniles is consistent with this phenology. The differences between the departure dates from the Taimyr breeding grounds provided by published sources and the dates of arrival at Puck Bay suggest that Knots cross the northern tundra regions very quickly (at least, the earliest birds to arrive do so). The numbers of juvenile Knots turning up on the Polish coast appear to depend not only on the lemming cycle in the breeding grounds, but also on other factors, like local weather conditions, which could influence the number of juveniles observed.
