Surveys were mainly conducted by 2-km-long line transect censusing in 993 quadrats (4.5 km×5 km). In addition, for 526 quadrats, census results obtained from the literature and spot censuses concerning the presence or absence of birds were also incorporated. The Lesser Cuckoo was distributed mainly in Hiyama and Oshima districts and the central part of Iburi district. These results indicate the Lesser Cuckoo to be a common summer visitor in these areas, and an irregular visitor in other areas in Hokkaido.","PeriodicalId":55867,"journal":{"name":"Journal of the Yamashina Institute for Ornithology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84539979","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}

{"title":"Estimating Population Size of the Crested Ibis Nipponia nippon Using Mark Resight Analysis","authors":"Y. Okahisa, H. Nagata, K. Ozaki","doi":"10.3312/JYIO.48.51","DOIUrl":"https://doi.org/10.3312/JYIO.48.51","url":null,"abstract":"The Crested Ibis Nipponia nippon became extinct in the wild in Japan in 1981, but was reintroduced on Sado Island in 2008, where the population has reproduced successfully since 2012. A total of 157 ibises is estimated to reside on Sado Island. To facilitate monitoring of survival and mortality, all the released individuals were individually identified through different combinations of color rings, and a uniquely numbered ring. However, because they were overlooked or present in inaccessible nests, not all wild-hatched nestlings were ringed for identification. In addition, the detection rate of the marked individuals might decline with an increase in the population size owing to the limited monitoring effort. Ministry of the Environment (MOE) has determined the number of unmarked individuals by the maximum number of simultaneous observations, and the number of marked individuals has been counted by subtracting the number of individuals that have not been observed for six months. Under such circumstances, the population size could be underestimated. To address this shortcoming, we fitted a mark-resight logit-normal model for estimating unmarked individuals, and a poisson-log model with robust design for estimating total population size including marked individuals, using program MARK. We also compared estimated numbers with observed ones. There were 8.48 unmarked individuals since the first successful reproduction in 2012. The estimated number reached a peak of 30.23 in 2014, but has gradually decreased to 20.30. In all study periods, the estimated number of unmarked individuals was larger than observed ones. However, the estimated number of marked individuals was almost the same as the observed one, but the numbers published by MOE were overestimations. At the end of September 2015, there were approximately 109 released and 41 wild-hatched individuals on Sado Island. When evaluating the reintroduction program, we recommend that the population size of the Crested 51 山階鳥学誌 (J. Yamashina Inst.

{"title":"Home Range and Habitat Use of a Male Copper Pheasant Syrmaticus soemmerringii in a Suburb in Tokyo, Japan","authors":"N. Kawaji, Toshio Hayashi, T. Matsuura","doi":"10.3312/jyio.48.29","DOIUrl":"https://doi.org/10.3312/jyio.48.29","url":null,"abstract":". The Copper Pheasant Syrmaticus soemmerringii is endemic to Japan, but nothing is known of its home range. We captured a male Copper Pheasant from the Tama Forest Science Garden in a suburb in Tokyo, Japan, and radio-tracked the bird from June 2003 to May 2004. Vegetation in the study area comprised a cherry arboretum, a mature cedar and cypress plantation, secondary evergreen broadleaved forest, mixed forest with many broadleaved trees invading the coniferous plantation area, and an arboretum planted with various tree species for exhibition. The home range, which was calculated using the minimum convex polygon method based on 138 ‒ 345 points seasonally, was smaller during summer and autumn (5.76 and 5.30 ha, respectively) than that during winter and spring (12.41 and 8.76 ha, respec-tively). The vegetation composition within the home range was significantly different from that of tracked points throughout the year. The bird spent significantly more time in the mixed forest area within its home range throughout the year, and also exhibited a significant prefer ence for the secondary broadleaved forest area throughout the year, except during autumn. However, the proportion tracked points within the cherry arboretum was significantly less than that within the entire home range throughout the year. The tracked male moved around with one female from September 2003 to March 2004, except during February. Two females and the tracked male moved together throughout the day during February 2004.","PeriodicalId":55867,"journal":{"name":"Journal of the Yamashina Institute for Ornithology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89042015","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}

We present here the first photographic evidence of a seabird, a Red-footed Booby Sula sula, capturing an airborne squid. When a school of squid took flight following disturbance by our boat, a booby flying alongside swooped and approached a flying squid from behind, caught it in the air and ascended quickly. Soon after swallowing the squid, the booby made a plunge-dive and caught another squid that had just landed in the water after a period in flight. Plunge-diving was subsequently repeated over a separate school of squid that had just re-entered the water after flight. Seabirds other than the Red-footed Booby may have frequent opportunities for finding and feeding on airborne squid.","PeriodicalId":55867,"journal":{"name":"Journal of the Yamashina Institute for Ornithology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87877121","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}
