Abstract The global pet trade provides a pathway for introduced species to invade new environments. Most studies use data as an indirect proxy propagule pressure exerted by the trade. Instead, we quantify reported rate of loss captive birds, assess factors that might influence this rate, simulate survival and retrieval birds overall cumulative on environment. We used online listings lost estimate exerts establishment bird in Aotearoa–New Zealand. Listings from two popular websites were monitored daily over 3.5 years, information was recorded frequency, location, composition characteristics events. investigated range may events, such season human population size. also developed simulation approach investigate Auckland, New Zealand's largest city. A total 1205 at least 33 nationwide during our monitoring period, 92% which parrots. found higher areas size median income, lower winter months. Simulation results predict any given month Auckland there is average 491 escaped including 136 potential breeding pairs, seven chance one locality has male/female pair large exceeds 80%.

Pigeon racing in South Africa: Exploring the socio-economic nature and extent of this 'unknown sport'

Geosport for Society, Год журнала: 2024, Номер 20(1), С. 25 - 45

Опубликована: Апрель 9, 2024

This research addresses the paucity of academic exploration into pigeon racing, a globally recognized sport with limited scholarly attention. While prior studies focused on ornithology and medicine, this paper pioneers comprehensive examination from geographical perspective. Employing quantitative methodology, study surveyed 712 members South African National Pigeon Organization (SANPO), providing nuanced understanding demographics, organizational structures, subjective values, economic impacts within racing. The study's findings reveal dominance males in sport, its multi-generational nature, widespread participation across diverse income groups. SANPO, 3,540 members, emerges as crucial entity sport's landscape. categorizes fanciers small, medium, large groups based bird ownership, presenting insights their socio-demographic context motivations. Pigeon-related activities are explored, emphasizing familial youth development aspects. analysis highlights industry's substantial job creation estimates total worth between R528,968,608 R1,620,390,112. By shedding light understudied aims to stimulate further provide foundation for informed discussions cultural, economic, social aspects

Опубликована: Май 9, 2024

The global increase in the pet trade and ownership of birds has heightened introduction emerging invasive vertebrate species. We analyzed online databases lost, found, sighted non-native bird reports South Africa to evaluate statuses, investigate geographic patterns, assess species trends, determine factors associated with lost birds. identified a total 1467 case representing 77 across nine families from websites (n = 3) Facebook pages 13). Most were within large cities, populated provinces, including Gauteng, KwaZulu-Natal, Western Cape. Psittacidae, Psittaculidae, Cacatuidae most dominant families, African grey (Psittacus erithacus), Cockatiel (Nymphicus hollandicus), Rose-ringed parakeet (Psittacula krameri) among top reported as lost. Lower-priced commonly there was no association between species’ price likelihood being found. In addition, we found positive relationship number shops, human population size, docility. There sharp cases 2019 onwards; however, males more frequently Our findings highlight challenges regulating monitoring need address kept conservation efforts. Online resources can be effective tools for passive surveillance species, especially potentially ones.

The global trade of non-native pet birds has increased in recent decades, and this accelerated the introduction invasive wild. This study employed ensemble species distribution modelling (eSDM) to assess potential habitat suitability environmental predictor variables influencing bird reported lost sighted South Africa. We used data information on found from previous studies establish describe scenarios how may transition captivity Our revealed that models fitted performed well predicting for African grey (

Citizen science survey of non-native Rose-ringed Parakeets Psittacula krameri in the Durban metropole, KwaZulu-Natal, South Africa

African Zoology, Год журнала: 2022, Номер 57(2), С. 90 - 97

Опубликована: Апрель 3, 2022

The Rose-ringed Parakeet Psittacula krameri (Scopoli, 1769) has become invasive in several countries, including South Africa, mainly through the pet trade releases and escapees. We conducted an online questionnaire survey targeting residents Durban, eThekwini Municipality, KwaZulu-Natal, Africa. aimed to determine distribution, habitat diet of Parakeet. also determined if public perceived parakeets as pests control measures were supported. found that many parakeet sightings reported Durban North, primarily around shopping centres. Approximately 64.5% respondents provided feeding stations for parakeets, with most providing seeds grains. A total 173 (55.4%) considered a pest. chase nine bird species, which seven native two non-natives. Most stated should not be controlled. However, those who supported their suggested shooting destruction eggs. concluded distribution is likely expanding associated anthropogenic activities this urban landscape. perceptions may make management difficult.

A Snapshot of the Global Trade of South African Native Vertebrate Species Not Listed on CITES

The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) aims to prevent the overexploitation species by controlling their trade. However, there is currently no international regulatory framework protect trade non-CITES species. We examined LEMIS database, online trade, scientific literature with aim identifying compiling a list South African native traded as pets wildlife products. found that are 223 products 95 pets. Mammals birds were most taxa for products, while reptiles amphibians mostly At least, not facing extinction, categorized Least Concern. some endemic have an unknown population size, Sclerophrys pantherina Neamblysomus gunningi being Endangered. pet involves 10 countries, USA, Czech Republic, UK largest importers. 20 USA major importer.

Conservation status and threats to lovebirds: knowledge gaps and research priorities

Lovebirds (genus Agapornis of family Psittaculidae) are a group small, colourful parrot species endemic to sub-Saharan Africa and Madagascar, two-thirds which considered have declining populations. Effective conservation efforts hampered by lack information, particularly for occurring in regions that received little research attention. We combined expert knowledge with review the primary grey literature identify key gaps priority actions this birds. Published studies were found be largely concentrated on lovebird populations southern and, lesser extent East Africa, therefore mostly concern members 'white eye-ring' clade. Some species, such as Black-collared Lovebird swindernianus, remain very poorly studied, even basic information georeferenced occurrence records. Several historically taken from wild large numbers international pet trade, leading population declines. Although trade lovebirds has been much reduced compared historical levels, considerable still captured local without any monitoring Habitat change continues drive declines range some those habitat specialists, Nyasa A. lilianae Black-cheeked nigrigenis.
