They are listed as Vulnerable internationally with habitat loss being the primary threat to the species. They nest in natural tree hollows in large forest hardwoods which were the target of historical, exploitative harvesting, and which continue to be harvested legally but on a smaller scale. The breeding biology of the species has been described for the central population, but not yet for the southern population, in the Eastern Cape province, where the stronghold of the population resides. There, few nest sites have been located, and the study of the breeding behaviour and biology is a key knowledge gap in the species in need of conservation. This study aims to characterise natural nesting sites in the Eastern Cape, describe breeding behaviour and investigate breeding success during 2017–2021. A total of 43 nesting sites were located of which 20 were occupied. No pairs attempted breeding in 2019 and breeding success was estimated to be 58%. As found in other parts of the range, Cape Parrots in the study area nest in existing hollows predominantly in large, mature, yellowwood Afrocarpus falcatus trees. Parrots also nest in exotic species. They showed no preference for nest orientation and nested as close as 69 m away from their nearest neighbour. Most nest cavities were inaccessible by field researchers and could only be monitored from the ground, but new methods were found that facilitated the inspection of some nests that were unsafe to climb. Nest characteristics and breeding behaviour information gathered in this study provide a practical foundation for the optimisation of the design and installation of more nest boxes in future, to assist in conservation efforts of this threatened species.","PeriodicalId":201369,"journal":{"name":"Afrotropical Bird Biology: Journal of the Natural History of African Birds","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121157756","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 56 km2 area of study was selected based on access from tracks and follows no formal boundaries. The site comprises a 10 km stretch of ocean beach, coastal dunes with patchy thicket forest, and low lying wet grasslands inland to the Incomati River. The wetlands have complex hydrology offering diverse salinity and temporal conditions. The peninsula of Praia de Macaneta is also included in the study site but with few data. Improved access to the site in Oct 2016 enabled over 200 field ornithological visits Oct 2016-Oct 2020 and the sightings are analysed and reported herein. A total of 295 species was recorded including eight Globally Threatened birds (three Endangered, five Near-threatened) and Internationally Important numbers of White-breasted Cormorant Phalacrocorax carbo and Whiskered Terns Chlidonias hybrida were found. Three new birds for Mozambique were discovered; Sharp-tailed Sandpiper Calidris acuminata (first for Africa), White-rumped Sandpiper C. fuscicollis and Pearl-breasted Swallow Hirundo dimidiate. An annotated checklist of selected species is presented. The Sharp-tailed Sandpiper in particular drew much birder interest with 254 international visitor days over the 12 weeks of its first visit Feb-Apr 2018, contributing over US$12,000 into the local economy. The bird returned for two further seasons but it was not possible to gather further data.","PeriodicalId":201369,"journal":{"name":"Afrotropical Bird Biology: Journal of the Natural History of African Birds","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127478210","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}

Little is known about the species’ vocalizations and song flight, and published descriptions are vague or confus-ing. Here I provide a detailed description of vocalizations and song flights as recorded between 2012 and 2019 in Limpopo Province, South Africa. Vocalizations were recorded using a digital recorder for calls in flight and occasionally on the ground, or were obtained from a video camera placed near the nest to record vocalizations that would be impossible to record from a distance. Twelve categories of vocalizations were identified, eight of them described here for the first time. The majority of the eight newly described vocalizations were obtained from video footage. A more detailed description of the song flight is also provided and should clarify some of the confusing descriptions provided in the literature. Knowledge of the flight song of Pink-billed Lark is valuable to locate and identify the species and will be an asset for moni-toring programmes and SABAP2.","PeriodicalId":201369,"journal":{"name":"Afrotropical Bird Biology: Journal of the Natural History of African Birds","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128118602","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}
