“…The average infestation levels of rodents and birds over the period of the crop growth was prominent in the no-protection eld plots than the protected plots and as a result the damage experienced from these infestations was more prominent under the no-protection eld plots which consequently resulted into a heavy crop loss estimate. This nding is in accordance with Khan et al (2015) who reported the effectiveness of eld protection against avian pests and other crop invaders in rice elds as it considerably reduce losses. The estimated grain yield loss in this study resulted from the combined infestations and damage induced by birds and rodents to the rice varieties and it negates the records of De May et al (2012) who reported the yield loss done by birds to cereal crops to be between 13% − 30%, Sarwar, (2015) who reported a crop loss by rodents to be about 6.06% and Kasso, (2012) who reported about 50% crop loss caused by rodents to rice crop grown in West Africa.…”

Rice (Oryza sativa L.) belongs to the family poaceae and has become the most popular food. Cultivation of this crop is been faced with the menace of vertebrate pests of which birds and rodents are the most implicated. This research, carried out during the 2020 and 2021 cropping seasons was to identify the bird and rodent pest species associated with lowland rice, determine their infestation status and quantify the losses induced. The experiment was a split-plot arrangement fitted into a Randomized Complete Block Design. Main plots were protection and no-protection, sub-plots were four rice varieties: Ofada, NERICA-L-34, ARICA-3, and WITA-4. Data collected were subjected to Analysis of Variance (p ≤ 0.05) and means were compared using Least Significant Difference (LSD). The bird pests identified were: Passeriformes - Ploceus melanocephalus Linnaeus (Ploceidae), Ploceus cuculatus Muller (Ploceidae) and Spermestes cucullatus Swainson (Estrildidae) while the rodent pest identified was Thryonomys swinderialus Fitzinger (Thryonomyidae). In 2020 and 2021, the infestation levels of birds and rodents were significantly (p < 0.05) higher under the no-protection plots (1.21 and 5.24) and (2.31 and 2.62) than the protected plots (0.00 and 0.56) and (0.00 and 0.18) respectively, the estimated bird- and rodent-induced losses ranged between 85.59% − 92.01% and 83.44% − 95.98% in 2020 and 2021, respectively. In conclusion, bird and rodent pests cause significant loss to rice crops and therefore, protection measures are recommended for optimum grain yield.

“…Studying the feeding ecology of invasive bird species has facilitated understanding of their species-specific diets around the world (Khan 2003;Fraticelli 2014). This has enabled a better understanding of the impacts posed by introduced bird species, especially on crops of economic importance such as apple Malus domestica, citrus Citrus spp., cherry Prunus cerasus, yellow guava Psidium guajava, mango Mangifera indica, sunflower Helianthus annuus, and maize Zea mays (Ahmad et al 2011;Canavelli et al 2013;Fraticelli 2014;Symes 2014;Menchetti and Mori 2014).…”

The Rose-ringed Parakeet Psittacula krameri is one of the world's commonest invasive bird species and has established in the South African urban landscapes. However, relatively little is known about the feeding biology of parakeets here. We surveyed areas in eThekwini Municipality, Durban, South Africa, to determine their feeding sites and the related land-use types. Patterns of the association were explored using Correspondence Analysis to determine parakeets' diet across seasons and interaction between different tree species fed on by parakeets and other bird species. Dietary items were determined visually using binoculars. We identified a total of 63 feeding sites with many in the urban built land-use cover type. The parakeets' diet differed significantly across the seasons with spring accounting for 33% of annual food items. We identified 31 fruiting/flowering tree species fed on by the parakeets, with fleshy fruits and flowers accounting for 58% and 19%, respectively. Native tree species (63%) were mostly relied on when compared with non-native (27%). They also fed on carpenter ants Camponotus cinctellus which contributed 3% of their diet. The forest fever-berry Croton sylvaticus (fleshy fruits) and African star-chestnut Sterculia africana (flowers) were the most preferred tree species in autumn and summer. The observed number of bird species that communally fed with parakeets were significantly different across the sampled seasons. The diets for the Common Myna Acridotheres tristis and the Speckled Mousebird Colius striatus overlapped with parakeets for most tree species. Parakeets were observed actively feeding in the early mornings and late afternoons before roosting. Our study supports that parakeets are generalist-opportunistic feeders. The assessment of Rose-ringed Parakeets feeding ecology may help understand their potential impact on native tree and bird species within an urban landscape.

“…It is reported to be invasive in countries such as Hong Kong , Singapore (Brook et al, 2003), Ismailia Governorate, Egypt (Kamel, 2014), Tanzania (Shimba and Jonah, 2016) and South Africa (Nxele and Shivambu, 2018). In its native Pakistan (Khan, 2003) and India (Dhindsa et al, 1991), it is regarded as a native invasive pest species.…”

Invasive birds: global trends and impacts

2020

View full text Add to dashboard Cite

This 381-paged book covers the biology, ecology, impact and management of 34 common alien invasive species, with reviews on the history and context of avian introductions and invasions in five major regions (Oceania, Africa, Europe (including the Middle East, Asia and South America)), as well as management challenges and the potential of citizen science for monitoring alien birds. The book pitches at the introductory level and is ideal for readers to gain a quick and comprehensive view of the current status of global avian invasions. It has brought the records and research of avian invasion one step ahead of other alien invasive animal taxa. Many chapters contain distribution maps and data tables on the diet and morphology of the species, providing a good reference for the species and its management issues. Each chapter also contains a rich list of references that could help readers dive further into the topic.
