This paper provides an overview of the results of a satellite telemetry study of Red Kites tagged in Austria, Slovakia and the Czech Republic. This is the first comprehensive study on the phenology of the species in Croatia. Between September 2014 and October 2018, a total of 39 tagged individuals have been recorded in Croatia and spent a collective total of 1484 days here. Red Kites mainly occurred in Croatia from September to March, while few birds remained here during the summer. Birds nesting in central Europe migrate through Croatia in broad front, appearing in all parts of the country, moving SW to wintering grounds in Italy, while fewer individuals follow the SE direction to Greece. Furthermore, the wintering behaviour of four tagged Red Kites were recorded using communal roosts in the continental part of Croatia. During the early spring of 2018, a female Red Kite tagged in the Czech Republic was suspected of breeding in Eastern Slavonia and later in the season the nesting was confirmed south of the town of Đakovo, even though it was unsuccessful.","PeriodicalId":159346,"journal":{"name":"Vol. 54 (2019)","volume":"82 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":"124798136","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}

Over the past year (2019), I have been studying egg dimensions of Great Tit Parus major in a deciduous forest in Mokrice and Krušljevo Selo area, in north-western Croatia. This species is secondary hole-nesting passerine and all studied Great Tits bred in nestboxes. The effect of laying order (or laying sequence) on egg dimensions was analysed in clutches with 11 eggs (the modal clutch size in research area in study period) and only first clutches included. Average egg length, egg breadth, egg volume and elongation index (egg shape) of 110 eggs (10 clutches) was 17.35 mm, 13.47 mm, 1609.64 mm3 and 1.29, respectively. In this study, there was no general trend of increasing or decreasing length, breadth and egg volume (egg size) in relation to the laying order (all p > 0.05). However, a negative correlation between egg shape and laying sequence was significant.","PeriodicalId":159346,"journal":{"name":"Vol. 54 (2019)","volume":"28 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":"133925491","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}

It is considered that only S. crassirostris breeds in Croatia. The data collected on this species in Croatia, however, is inconsistent as some ornithologists still use either name. In order to discern whether both species oc-cur in Croatia, I conducted a study of citizen science data and a review of skins in three museum collections. There was a specimen of S. hortensis in the collection of the Institute of Ornithology, collected on the island of Brač in 1964. Citizen science data yielded no verifiable observations of S. hortensis in Croatia. Bill length was an unreliable distinction characteristic between the two species, while plumage characteristics proved useful only for adult birds. Reliable distinction characteristics are thus song, tail and moult pattern and mt-DNA. Detailed studies of Orphean Warblers’ distribution and characteristics in Croatia and Italy are recommended.","PeriodicalId":159346,"journal":{"name":"Vol. 54 (2019)","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":"126237233","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}

The European Roller has been found at four sites situated along the Adriatic coast: Marlera I and Šandalja II in the northern Adriatic, and Vela Spila and Markova Spilja on the southern part. The oldest find is from Marlera I, which dates back to the Late Pleistocene (Marine Isotope Stage 3 MIS 3) and the youngest are the Holocene (MIS 1) finds at Vela Spila and Markova Spilja. Immature bones were found in Vela Spila deposits, indicating breeding during the Late Pleistocene in the southern Adriatic. So far, the European Roller has not been determined in deposits from continental Croatia.","PeriodicalId":159346,"journal":{"name":"Vol. 54 (2019)","volume":"41 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":"126040715","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}
