I compared some breeding characteristics (laying date, clutch size, number of hatchlings and number of fledglings) of first clutches of the Common Starling for different nestbox sizes. There was no any statistically significant difference found between parameters for “normal nestboxes” with a floor area of 256 cm² and “small nestboxes” with a floor area of 121 cm² (all comparisons with p > 0.05). My results are aligned with those papers that have illustrated no connection between breeding performance parameters and nestbox size in secondary hole-nesting passerines.","PeriodicalId":330055,"journal":{"name":"Vol. 56 (2021)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128267981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Jurinović","doi":"10.21857/yvjrdcl2wy","DOIUrl":"https://doi.org/10.21857/yvjrdcl2wy","url":null,"abstract":"The Caspian Gull is a breeding species of eastern Europe and central Asia, whose breeding range has over the last 100 years been expanding to western parts of Europe. It is regularly seen on migration and wintering in Croatia. Since the historical literature data for Larus cachinnans in Croatia mainly refer to the Yellow-legged Gull, the aim of this research was to determine the origin of Caspian Gulls wintering in Croatia. Recoveries from the Prudinec rubbish dump in Zagreb and the ones ob-tained from the ringing archive of the Institute of Ornithology, Croatian Academy of Sciences and Arts have been analysed. Ringed individuals seen in Croatia belong to the populations from central and eastern Europe, and the first ringed individual from the Black Sea population has been recorded. Compared to the available literature data, four new countries of origin of Caspian Gulls seen in Croatia have been recorded: Lithuania, the Czech Republic, Hungary, and Romania. The longest distance from the place of recovery (Croatia) to the place where the individual has been ringed (Ukraine) is 1507 kilometres. Ringed individuals were recorded in Croatia from October to March.","PeriodicalId":330055,"journal":{"name":"Vol. 56 (2021)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126533378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here the results related to the population trend and reproduction parameters and phenomena called colony shifting based on a 40-year research (1981 – 2021) are presented. The population declined from about 110-150 pairs in 10 colonies in 1981 to 78-95 pairs in 6 colonies in 1999, and subsequently increased to 141-150 pairs in 6 colonies in 2013. Since 1999, there have been no Griffons nesting in Paklenica, and it is possible that they all shifted to Kvarner, where 13% increase was recorded in 2000. In 2021, the total number was about 120 pairs on 5 islands: Cres, Plavnik, Krk, Prvić and Pag. Population density was estimated at 32.5 adult individuals/100 km 2 and 13.75 breeding pairs/100 km 2 .

In the field survey on Lastovo and the islet of Mrčara in July 2017, the occurrence of four owl species was confirmed: the Eurasian Scops Otus scops , the Little Athene noctua , the Long-eared Asio otus and the Tawny Owl, while the occurrence of the Eagle Owl Bubo bubo is uncertain according to the literature review. The most frequently recorded owl species was the Eurasian Scops Owl. The successful breeding of the Tawny Owl on Lastovo was confirmed for the first time. Its diet was dominated by mammals, with 97% of prey by number, and 99% by biomass. By far the most common prey was the Long-tailed Field Mouse Apodemus sylvaticus , as well as the Black Rat Rattus rattus in terms of biomass. Birds were of marginal importance as prey of the Tawny Owl, at least in the summer months.","PeriodicalId":330055,"journal":{"name":"Vol. 56 (2021)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129665138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
