Aims To investigate the effects of sex, weather conditions, seasonality, and breeding stage on body mass of the Village Weaver Ploceus cucullatus and Northern Red Bishop Euplectes franciscanus in Amurum Forest Reserve, Central Nigeria. Methods Biometric data were extracted from a Constant Effort Sites database of over 15 years and daily rainfall and temperature data were obtained from Jos Metrological Center. We used a general linear mixed model to determine the effects of sex, rainfall, temperature, and season on body mass variation of the two species within and across years, and differences in body mass of females of the two species within and across years with daily rainfall and temperature, and season during the different incubation stages. Results The body mass of males was higher than that of females in both species. Daily rainfall and mean temperature were negatively related to body mass in Village Weavers, while in Northern Red Bishops rainfall was positively related to body mass. In both species, female body mass varied according to brood patch status: female Village Weavers were heavier during the egg-laying stage compared to the non-breeding season; female Northern Red Bishops weighed more at incubation or brooding stages and less during the chick rearing stage when compared to the non-breeding season. The body mass of females did not correlate with daily rainfall and temperature, or season. Conclusions Our results showed the effect of sex on body mass in both species of weaver. The variation in body mass of these species during breeding, and with local weather conditions, suggests how the species manage body mass within a tropical African environment.","PeriodicalId":55353,"journal":{"name":"Bird Study","volume":"69 1","pages":"83 - 89"},"PeriodicalIF":0.7,"publicationDate":"2022-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49211803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods We draw on field experience and case studies to illustrate how potential climate change impacts on invertebrates may cascade to affect bird populations and identify some key research gaps for urgent consideration. Results We highlight four invertebrate groups which may be sensitive to the impacts of climate change and that have the potential to impact bird populations that feed on them: soil invertebrates, foliar invertebrates, aerial insects, and aquatic invertebrates. Conclusion Our ability to understand these impacts is hampered by a lack of extensive long-term monitoring data for many invertebrates, and invertebrate data collected at scales that can be related to bird populations. We call for collaboration between entomologists and ornithologists, both non-vocational and professional, to support new empirical research and long-term monitoring initiatives to better link changes in insect populations and birds to inform future decision-making. This will be particularly important to understand likely future increasing climate change pressures on birds.","PeriodicalId":55353,"journal":{"name":"Bird Study","volume":"69 1","pages":"59 - 71"},"PeriodicalIF":0.7,"publicationDate":"2022-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41421826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aims To determine the composition Common Kingfisher diet in an area recently colonized by non-native fish species, and to compare estimated prey size during the winter to that of fish fed to nestlings during the breeding season. Methods The diet was studied by analysis of pellets collected from the River Duero (lentic, still water) and River Pisuerga (lotic, riverine) in central Spain. Fish size (total length and biomass) calculated from paired remains contained in each pellet. Results Prey items were almost exclusively fish (94.9% of all prey), with a small proportion of non-native Red Swamp Crayfish Procambarus clarkii (4.9%) and aquatic insects (0.2%). The diet consisted of only five species of fish, all of which were non-native. The Common Bleak Alburnus alburnus and Eastern Mosquitofish Gambusia holbrooki were the prey captured most often in the River Pisuerga and River Duero, respectively. Estimated length of fish prey ranged from 1.5 to 10.5 cm, but 53.6% of individuals were between 3 and 5 cm. Mean biomass of the fish consumed was also small (1.08 g per fish). Mean values of both fish total length and biomass were lower than the measurements reported elsewhere in Europe during the breeding season. Conclusion Native fish species have disappeared from the diet of Common Kingfishers in our study area, probably because the non-native species are more common.","PeriodicalId":55353,"journal":{"name":"Bird Study","volume":"69 1","pages":"97 - 102"},"PeriodicalIF":0.7,"publicationDate":"2022-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44392762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aims To investigate bird species richness patterns across different habitat types in Czechia, Central Europe. Methods Data from a national breeding bird monitoring scheme in Czechia, based on mapping of positions of individual birds along transects, were used to express the number of species in habitat polygons. Each polygon was represented by one of the eight habitat types (coniferous, mixed and deciduous forest, cropland, grassland and other open habitat types, urban habitat, and wetland) obtained by detailed country-wide vegetation mapping. Species richness of individual polygons was related to polygon habitat type and area by linear mixed effects models, taking the surrounding land cover composition into account. Results Bird species richness was highest in forest, as predicted, and respective forest habitat types did not differ from each other. Urban habitat hosted a similar number of species as forest. Species richness varied greatly between different open habitat types: cropland was the most species-poor of all the habitat types considered, whereas grassland and other types of open habitats hosted significantly more species, albeit fewer than forests, and did not differ from wetland. Slopes of species-area relationships in respective habitat types largely followed the patterns in species richness. Conclusions The observed patterns are partly driven by natural habitat characteristics, such as high vertical stratification of forest vegetation facilitating coexistence of a higher number of species. However, biogeography may also play a role, for example, and the relatively short time periods for colonization from Eastern European source areas may underpin lower bird species richness in grasslands. In addition, human interventions may drive the steep slope of the species-area relationship in forest, presumably caused by mosaic harvesting, as well as the shallow slope of this relationship in cropland and wetland, as a result of their intensive exploitation.","PeriodicalId":55353,"journal":{"name":"Bird Study","volume":"69 1","pages":"72 - 82"},"PeriodicalIF":0.7,"publicationDate":"2022-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42781436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aims To describe for the first time a commensal relationship between the Red-billed Chough and the Barn Owl during the breeding period. Methods During systematic monitoring of 90 nest boxes installed for Barn Owls in Navarre, northern Spain, it was found that in some boxes, Barn Owls and Red-billed Choughs nested simultaneously (inside and on top of the box, respectively). The clutch size, breeding success, and the number of fledglings of each species were compared when nesting together versus separately during the breeding period of 2015 and 2017. Results About one-third of the nest boxes observed during the study were simultaneously used by both Barn Owls and Red-billed Choughs. No relationship was found between the composition of the habitat around the boxes and the degree of occupancy for either species. Nest box sharing had no significant effect on the breeding output of Barn Owls, but improved the breeding performance of Red-billed Choughs by increasing the number of fledglings in relation to clutch size. Conclusion Barn Owls can provide benefits to Red-billed Choughs by controlling the populations of rodents, which could act as nest predators. Given that Barn Owls apparently do not obtain benefits nor incur any costs by the association with Red-billed Choughs, this interaction may be defined as commensalism. To our knowledge, this is the first documented nesting association between a corvid and an owl species.","PeriodicalId":55353,"journal":{"name":"Bird Study","volume":"69 1","pages":"90 - 96"},"PeriodicalIF":0.7,"publicationDate":"2022-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58617214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
