Here we present an account of the urban bird diversity of Stellenbosch, South Africa, derived from daily observations of species presence collected during the initial two stages of the country’s nationwide COVID-19 lockdown period (66 days). A total of 38 bird species were observed during this time, including sightings of urban hunting behavior for birds of prey and greenspace foraging in general. The most commonly seen taxa were typical human-commensal species, including sparrows and doves. Many species were encountered far less frequently, with 21 of the 38 species being observed on less than 10 days. This was most notable for birds of prey (n = 6 species from Accipitriformes and Falconiformes) or African swifts (n = 2 species from Apodiformes), which were recorded only a few times for any given species. Our account provides some relatively niche information regarding the presence of birds from a single city block in South Africa and notes interesting observations of urban foraging behaviour, but also underscores the value of birdwatching during times of uncertainty.","PeriodicalId":155392,"journal":{"name":"Biodiversity Observations","volume":"123 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123070943","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 one of the most invasive ecological pests in the world and threatens native flora, agriculture, human and animal health outside its natural range. While dry and semi-arid climatic re-gions are supposed to be immune to its invasion, our data show that this is not always the case. Ranthambhore National Park is dry, de-ciduous forest located in semi-arid part of western India. We have observed the progressive invasion of L. fulica in this fragile land-scape since its first introduction in 2010. Subsequently, it has spread over a large area at an alarming rate. We discuss the observations on behaviour and the factors responsible for the rapid spread of L. fulica in the park.","PeriodicalId":155392,"journal":{"name":"Biodiversity Observations","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127071916","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}

Nest usurpation may result from a population increase of the usurping species and the limited availability of suitable nesting sites. With raptors, interspecific competition for nesting sites with other non-raptor bird species is a rarely documented phenomenon, particularly when it results in mixed interspecific clutches and misdirected reproductive behaviours. I observed a pair of Common Kestrels Falco tinnunculus, without its own clutch, incubating a clutch of two feral pigeon Columba livia eggs. The incubation occurred in the feral pigeons’ nest in southern xerophytic scrub on Tenerife Island during the 2020 breeding season. We checked the focal kestrel territory from 18 March to 20 May once a week. To our knowledge, this represents the first record of a Common Kestrel pair incubating eggs in the non-raptor bird species’ nest in the wild. We discuss some factors which could influence kestrels to display this behaviour.","PeriodicalId":155392,"journal":{"name":"Biodiversity Observations","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131231464","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}
