Studies show that field management and flooding cycles influence the reproductive parameters of these birds. L'Albufera de València, on the east coast of the Iberian Peninsula, has large areas of rice fields and is home to the third largest breeding colony of herons in Spain. Changes in water and rice field management that have occurred since the colony was last assessed (1990) may have affected the colony's reproductive performance. Clutch and brood size, and hatching, nesting and breeding success were estimated for Grey Heron Ardea cinerea, Purple Heron Ardea purpurea, Cattle Egret Bubulcus ibis, Little Egret Egretta garzetta, Squacco Heron Ardeola ralloides (Ardeidae) and Glossy Ibis Plegadis falcinellus (Threskiornithidae) in 2015–2017. The extent of flooding and cultivation of rice fields was assessed from February 2016 to June 2017. Reproductive parameters were related to the state of the rice fields. All reproductive output parameters were lower than those reported in the literature. In 2016, laying started earlier (at the end of April), when the fields were still dry and hatching started from May, after flooding. In 2017, peak hatching occurred in June, when the fields were sown. A significant relationship was found between breeding success and the area of sown fields, except for the Squacco Heron. We found that birds that initiated egg laying closer to the date of flooding had a relatively higher breeding success for the Little Egret, Glossy Ibis, Cattle Egret and Purple Heron. The success of nesting populations in this type of artificial wetland requires water management plans that synchronize flooding regimes and maintenance of flooded areas with the biological requirements of these species.","PeriodicalId":55463,"journal":{"name":"Ardea","volume":"109 1","pages":"149 - 165"},"PeriodicalIF":0.4,"publicationDate":"2021-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42570527","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}

These include shorter fallow periods between ‘jhum’ (shifting cultivation) cycles which give less time for forests to recoup, along with encroachment, logging and other developmental activities. This is leading to widespread habitat loss and degradation. In such a scenario, Community Reserves that largely make up the Protected Area network in Northeast India could likely act as refugia for several species. Our study explored how owls use these Reserves in the Garo Hills in Meghalaya. We conducted three temporal replicates in thirty-three 500 × 500 m grids between January and March 2020. Ecologically relevant site and sampling covariates were quantified in each grid along with owl counts. Occupancy and N-mixture models revealed that wind speed, temperature, humidity and survey start time had the greatest effect on the detection probability of owls. On the other hand, occupancy and abundance were most influenced by slope, distance to water body, disturbance and tree structural characteristics (girth and tree height heterogeneity). With these findings, we highlight the importance of preserving water bodies and old-growth forests in Community Reserves of the Garo Hills landscape, which seem to be acting as refugia for the Brown Wood-owl Strix leptogrammica, an old-growth forest specialist thought to be currently in decline.","PeriodicalId":55463,"journal":{"name":"Ardea","volume":"109 1","pages":"185 - 199"},"PeriodicalIF":0.4,"publicationDate":"2021-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47361529","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}

Diet specialization has been reported in many raptor species and it may be an important driver of intraspecific population structure. Here, we quantify the diet of Peregrine Falcons Falco peregrinus from five breeding territories on an island determined from prey remains collected over four breeding seasons. Three prey species accounted for 69.8% of total prey frequency, with Manx Shearwater Puffinus puffinus being the primary prey accounting for 47.3% by frequency and 40.8% by biomass. European Herring Gull Larus argentatus was the second most important prey species by frequency (13.8%) and biomass (29.8%) followed by Feral Pigeon Columba livia (frequency: 8.7%, biomass: 7.0%). Prey frequency on specific prey groups varied substantially between breeding pairs and months. Two pairs specialized on Manx Shearwater, one pair specialized on Herring Gull and Manx Shearwater, with the remaining two pairs having a relatively generalist diet of Manx Shearwaters, Feral Pigeon and small passerines. Prey frequency on Manx Shearwaters increased throughout the breeding season with a peak in total diet frequency of 63.8% in July, with a concurrent decrease in Herring Gull prey frequency. Higher percentage of Manx Shearwater in the diet explained 87% of the variation in a narrower dietary breadth for the Peregrine pairs. Our results suggest individual diet specialization may be one of multiple factors important for understanding population density in insular raptor populations.","PeriodicalId":55463,"journal":{"name":"Ardea","volume":"110 1","pages":"1 - 9"},"PeriodicalIF":0.4,"publicationDate":"2021-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49451877","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}

Using partial mitochondrial ND2 and ND3 gene sequences from populations throughout the distribution ranges and ecological niche modelling, we investigated the genetic structure and biogeographic history of these bird species. Two well-differentiated and supported clades in each species indicated a reciprocal monophyly with no gene flow between birds in the Zagros Mountains and other populations. Ecological niche modelling suggested population contraction in their potential habitat during the Last Glacial Maximum. The genetic differentiation in Zagros Mountains indicates that the post-glacial colonization of most of the Rock Nuthatch distribution range occurred from refugia located elsewhere than the Zagros Mountains. Given that Rock Nuthatches in the Zagros Mountains have long constituted an isolated population, there may be two phylogenetic species within each Rock Nuthatch species.

Waterbirds are an exception however, since midwinter surveys have been implemented in most areas of the world for over four decades. The Dalmatian Pelican Pelecanus crispus is a globally threatened emblematic wetland species of the Palearctic, with a wide distribution in Europe and Asia. Its global population is divided into three distinct groups that coincide with the Black Sea-Mediterranean Flyway, the Central Asian Flyway and the East Asian Flyway. In this study we used International Waterfowl Census data to assess long-term changes in the wintering population of the Dalmatian Pelican pertaining to the Black Sea-Mediterranean Flyway. We report national and regional population trends in SE Europe and Turkey and explore spatiotemporal patterns in the wintering numbers and distribution of the species in relation to climate variability during the last two decades. Our key findings suggest that during the past 30 years the abundance of wintering Pelicans increased across the entire study area. Within the eastern subpopulation this increase was most accentuated in the northern edge of the species' wintering distribution, which was associated with a local warming trend, and was coupled with a north-eastern shift in the distribution pattern, yet not driven by climate conditions. Other contributing factors, such as winter site fidelity, local food availability, finer scale climatic and habitat conditions, but also carry-over effects should be considered in future studies. Given the advancement of first laying dates in Dalmatian Pelicans in almost all breeding sites and the strict timing of IWC counts, we also propose the implementation of species-specific winter surveys, independently from IWC, to obtain a more thorough understanding of the dynamics of the Dalmatian Pelican's wintering population.","PeriodicalId":55463,"journal":{"name":"Ardea","volume":"109 1","pages":"1 - 23"},"PeriodicalIF":0.4,"publicationDate":"2021-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45242947","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}

It is traditionally considered to be one of the most complex problems in the taxonomy of Palearctic birds. We present new data on the genetics, morphology and bioacoustics of the Chiffchaff taxa found in Turkey, the Caucasus, Transcaucasia and Kopet Dagh: ‘greenish' brevirostris, caucasicus, menzbieri and ‘brownish' lorenzii. In southern Turkey, two Chiffchaffs were identified which carried a novel haplotype, recently discovered in Northern Israel. Both individuals from Turkey looked somewhat brighter and more yellowish than typical brevirostris, but their song clearly corresponded to the brevirostris dialect. The form brevirostris, inhabiting the western and central regions of Northern Turkey, was found to be the most distinct among all ‘greenish’ taxa, due to its small body size, wing formula and distinct vocal dialect. Paradoxically, the mitochondrial DNA of brevirostris is almost identical with caucasicus, whereas, in this respect, menzbieri is different from both. We believe that this paradox can be explained if we suppose that caucasicus originated during the ancient hybridization of brevirostris and menzbieri. The relationships between brevirostris and lorenzii, in the mountainous regions of eastern Turkey, show the mismatch between phenotypic and genotypic traits in some individuals that could also be a result of hybridization.","PeriodicalId":55463,"journal":{"name":"Ardea","volume":"109 1","pages":"1 - 16"},"PeriodicalIF":0.4,"publicationDate":"2021-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45891777","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}

At these locations, we used fixed-width transects to estimate its abundance and densities in different habitats for eight months. We monitored its reproductive biology, through behavioural observations and nest tracing during 12 months. The species was only present in plain areas with sparse short vegetation, using grassland, cropland or a mix of the two. Population densities varied significantly between habitats, being high (5.7 birds/ha) in extensive grasslands and medium to low in mixed cropland-grassland (1.1 birds/ha) and cropland (0.41 birds/ha). These differences may be related to the presence of grazing, flooding dynamics, the density of perennial forbs, the size of the grassland fields and the detrimental effect of toxic pesticides used for crop production. We estimated that 133 to 230 (95% CI) individuals (mostly adults), inhabit the entire reservoir. This is a significant number since it may represent 13–23% of the Colombian Horned Lark population.
