In this study, we describe the nest size characteristics and the breeding attempt of Little Crake (Zapornia parva) in the abandoned nest of Common Coot (Fulica atra) at the small mid-field pond in the Masurian Lake District, northeast Poland. Based on the 6-year study during five breeding seasons, we found 123 nests of Little Crake, but such an instance was observed only once. To the best of our knowledge, this observation is the first record of the use of the same nest by two species of rallids. We discuss what could force crakes to make such a decision, why this breeding attempt failed and why such instances are so rare in marsh-nesting species. The nest size in mid-field ponds localized in northern Poland was slightly smaller than that recorded in fishponds in the Czech Republic, but larger than the records obtained in lakes in Germany and Russia.

Overexploitation of resources represents a major factor in biodiversity loss. The illegal capture and trade of wildlife species pose a serious threat to them. Algeria is a party to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) since 1982, thereby joining the dynamics of wild fauna and flora protection. The list of wildlife species was last updated by Executive Decree No. 12-235 of 24 May 2012. In Algeria, songbirds are greatly appreciated as pet animals by pet enthusiasts. Unfortunately, habitat loss as a result of repeated forest fires in the Mediterranean region and the illegal capture of these birds cause severe damage to wild populations. The European goldfinch is the preferred species of bird enthusiasts because of its beautiful colours and its very particular singing abilities. Other species like the European serin (Serinus serinus) are, however, used for breeding with the European goldfinch and thus the creation of hybrids. For the purposes of assessing both the impact on populations and the economic impact of the illegal capture and trade of wild birds, a survey has been conducted on the bird market held, on a weekly basis, in the city of Guelma. According to the results, between 3000 and 12,000 European goldfinches are caught every year and around 1200 are sold solely on this market. As far as the European serin is concerned, the capture is estimated at over 1000 birds. The economic impact of this activity only for the sale of recently caught animals is estimated at more than USD80,000 per year.

This study examined foraging niche partitioning among coexisting species of shorebirds on a sandy beach dominated by a single food type, Horseshoe Crab (Limulus polyphemus) eggs, where use of foraging microhabitats of limited variety is temporarily restricted due to tidal cycle. The major goal of the study was to examine whether co-occurring species differed in selection of foraging microhabitats and use of feeding techniques. Ruddy Turnstone (Arenaria interpres), Red Knot (Calidris canutus), and Sanderling (Calidris alba) foraged significantly more on sand and gravel compared to pools and swash zone, Semipalmated Sandpiper (Calidris pusilla) foraged significantly more on sand and gravel compared to swash zone, but not significantly more compared to pools, while differences in use of microhabitats by Dunlin (Calidris alpina), and Short-billed Dowitcher (Limnodromus griseus) were non-significant. Turnstones used digging and turning stones, and pecking significantly more than probing, Semipalmated Sandpipers used pecking significantly more than probing, while all other species used probing significantly more than pecking. Knots and Sanderlings had the highest level of overlap both in use of microhabitats and foraging techniques, while turnstones and dowitchers had the lowest. Ruddy Turnstones were the only birds that used digging and turning stones to obtain food and these two foraging methods seemed to be the most important variables discriminating turnstones from other co-occurring shorebirds. However, despite the slight differences in use of foraging methods and microhabitats by different species, this study documented weak partitioning among shorebirds, particularly between sandpipers and dowitchers. These results indicate that the short-term absence of clear niche partitioning on a local scale may occur in shorebird communities.

Seed dispersal by birds is a pivotal ecosystem function worldwide; yet, the rapid and ongoing global biodiversity loss poses a major threat to this essential ecosystem service. Seed dispersal effectiveness (SDE) is a key outcome of the interaction, represented by the product of seed dispersal quantity (number of seed dispersed) and quality (probability of recruitment of dispersed seeds). Therefore, identifying functional equivalent species in terms of SDE should become a key issue for bird conservation, since the effects of local extinctions on seed dispersal services may be weakened by remaining equivalent species. However, a method to quantitatively identify functional equivalent species in frugivorous bird assemblages is still lacking. To estimate SDE overlap between seed dispersers and assess whether two species may be functionally equivalent, I apply a novel nonparametric niche overlap index based on kernel functions and null models to test its statistical significance. For each bird species, I account for intraspecific variation in seed dispersal effectiveness to obtain a distribution of seed dispersal effectiveness values, an often neglected source of variation in seed dispersal assemblages. Non-significant differences in seed dispersal effectiveness overlap support the hypothesis that two species are functional equivalent, thus playing similar functional roles. The model proposed is applicable to any other quantity or quality component and is independent from the method or sampling design used to quantify SDE. The identification of functional equivalent species in seed dispersal assemblages adds to the theoretical framework of seed dispersal effectiveness and offers new insights into the ecology of the seed dispersal service provided by birds.

The brood size in the Finnish Northern Goshawks seems to be associated with the breeding habitat and the availability of suitable prey. In this study, we examined these relationships in three study areas of different landscape structure in southern Finland, including a recently colonized urban area. The most abundant prey categories found in the food remains of the goshawk included corvids, turdids, columbids, gallinaceous birds, and squirrels. Corvids dominated in the diet samples of all the study areas. The number of turdids and columbids in the samples was significantly higher in both the rural and the urban habitats than in the wilderness area. The number of gallinaceous birds was significantly higher in the wilderness area than in other habitats. Gallinaceous birds, particularly tetraonids, the traditional staple food of the Northern Goshawk in Finland, seemed to be largely compensated by corvids in the wilderness area and by corvids and columbids in the rural and urban areas. The amount of corvids in prey showed a positive relationship with brood size, suggesting some particular importance of this prey in the goshawk diet. In all, diet seemed to explain partly between-landscape variations in the brood size of the goshawk. The brood size was significantly higher in the urban landscape than elsewhere.

The Hazel Grouse (Tetrastes bonasia) is considered an indicator of the naturalness and heterogeneity of the forest environment. This species occurs in various woods and forages on a variety of plants. The aim of this study was to verify the hypothesis that, in Norway spruce-dominated forest stands, the Hazel Grouse compensates for habitat poverty using non-forest areas and harsh topography, which deliver food resources and shelter for the birds. We compared 14 environmental and topographic variables in forest patches occupied and unoccupied by the Hazel Grouse in the Tatra Mountains (South Poland). Multivariate modelling showed that crucial factors for Hazel Grouse occurrence in spruce-dominated high-mountain forests were southern or western exposures, the presence of streams or glades and a multilayer forest structure with lower plant species richness in the undergrowth layer. Moreover, this species avoided clearcuts and depended either on wild sites (with a high share of deadwood and treefall gaps in mature stands at higher altitudes) or juvenile stands. The results of our study confirmed that gaps in forests and diverse topography could compensate the Hazel Grouse for habitat deficiency. These findings may be important for effective protection of this species in high-mountain spruce-only dominated forests.

Several North African wetlands are classified as wetlands of international importance (Ramsar sites and Important Bird Area) because thousands of Shelducks (Tadorna tadorna) winter in these habitats. However, Shelduck’s patterns of habitat use in these protected wetlands during the wintering season are still hindered by lack of information in arid and semi-arid regions regarding population dynamics and the effects of climate variables. This ornithological survey aims to study population dynamics and temporal patterns of diurnal activities of the Shelduck at two Ramsar and Important Bird Area sites (Chott Tinsilt and Sebkhet Ezzemoul) with respect to the effect of climatic parameters of the habitat in order to deepen our understanding of wintering strategies and habitat use. Populations were weekly censused from 06:00 to 19:00 during the entire wintering season (September 2015–May 2016). Diurnal behavioural activities were monitored at the same rate, and then the variation of time budget was tested using generalized linear model to determine the effects of climate variables and conspecific density dependence. The Shelduck was observed at both sites from the end of November and remained there until the total desiccation of both lakes in early May. Trends of Shelduck’s population dynamics differed between the two sites. Generalized linear models revealed the significant effects of temperature, wind speed and number of snowy days on population dynamics. Feeding was the main diurnal activity of the Shelduck at both sites with 80.2% of time budget at Chott Tinsilt (mainly feeding at lake shores) and 82% at Sebkhet Ezzemoul (mainly feeding in water). The generalized linear models showed that the variation of time budget allocated to different diurnal activities was not density-dependent, but rather it was negatively affected by the increase of air temperature. Significant effects of the interaction between population size and some climatic variables were found and discussed. During the whole wintering season, Chott Tinsilt and Sebkhet Ezzemoul play an important ecological role since they offer a wide-ranging diurnal forging habitat and a shelter for thousands of this waterfowl.

The Brolga (Antigone rubicunda) is a large Australian crane species with a broad distribution spanning from the tropical north to the south-eastern regions of the continent. Brolga populations throughout New South Wales, Victoria and South Australia have been in decline since the early twentieth century, with the species being listed as vulnerable in each state. To aid future conservation of the species, its taxonomic status needs to be validated, and patterns of gene flow and population connectivity across the species distribution need to be understood. To assist future genetic studies, we developed a suite of polymorphic microsatellite markers and the complete mitochondrial genome sequence by next-generation sequencing. A total of 18 polymorphic loci were characterised using DNA extractions from 47 individuals, comprising 30 and 17 individuals from Victoria and northern Australia, respectively. We observed moderate genetic variation across loci with only a single locus deviating significantly from Hardy–Weinberg equilibrium. De novo and reference-based genome assemblies were used to assemble the A. rubicunda mitochondrial genome sequence, which consists of 16,700 base pairs, and a typical metazoan mitochondrial gene content and arrangement. We test these new markers by conducting a preliminary analysis of genetic structure between south-eastern and northern Australian Brolga populations. Mitochondrial analyses provided evidence of shared haplotypes across the species range supporting the conspecific status of extant populations, while microsatellite markers indicated weak but significant genetic differentiation suggesting gene flow is limited. We discuss the implications of these findings and the benefits that these genetic markers will provide for future population genetic research on this iconic Australian bird species.

We discuss the implications of these findings and the benefits that these genetic markers will provide for future population genetic research on this iconic Australian bird species.","PeriodicalId":55408,"journal":{"name":"Avian Biology Research","volume":"12 1","pages":"49 - 58"},"PeriodicalIF":0.6,"publicationDate":"2019-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/1758155919832142","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47917361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The vegetation structure surrounding nest sites is a crucial component of habitat quality and may have large effects on avian breeding performance. Habitat quality reflects the extent to which the environmental characteristics of an area correspond to the preferred habitat characteristics of the species. The concentration of haemoglobin is considered a simple biochemical indicator of nestling body condition. We present results concerning the effects of variation in habitat characteristics on the concentration of haemoglobin in the blood of 14-day-old nestlings and breeding success of European Pied Flycatchers (Ficedula hypoleuca) in a mature mixed deciduous forest in central Poland. The haemoglobin concentration of nestlings was higher when there were more native oaks and deciduous, native trees on the territory. Breeding success was reduced by the number of alien oak (the Red Oak, Quercus rubra) and other alien deciduous trees, but increased by the number of native oaks in the territory. This study was conducted on only one site so further research is needed to examine the broader applicability of our results. Our data support the idea that haemoglobin concentration may serve as a simple indicator of body condition in nestlings and is useful in field ecophysiology studies of European Pied Flycatchers.
