“…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). Some parrot species, for example, are regarded as one of the agricultural pests in both their native and invaded areas (Mukherjee et al 2000;Kale et al 2014;Shiels et al 2018). The invasive Monk Parakeet Myiopsitta monachus in Barcelona, Spain, has been associated with damage to commercial crops such as tomato Lycopersicon esculentum, maize, and pear Pyrus communis (Senar et al 2016).…”

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.

“…In three of the visited farms, we noticed plots with heavily damaged areas around the edges. (Kale et al, 2014) and (Dawson, 1970) point out that sparrows tend to concentrate on certain areas in cereal parcels, and that they continue feeding until the food in this area is exhausted before moving to a new area. Our results also reveal a positive relationship between the density of ears per sampled square and the number of damaged ears.…”

The current study was carried out in 2016 and 2017 in eight cereal farms in Ouargla, in the north of Algerian Sahara. The damage caused by hybrid sparrows on cereals (barley and wheat) showed that the loss due to individuals of (Passer domesticus x P hispaniolensis)on cereal plots varies between the visited farms and fluctuates between 0.28% (0.22 qls / ha) and 15.6% (10.8 qls / ha). In general, the damage caused by the sparrows was found to be more important on the periphery of the plots than in the centersof these plots. A significant relationship was found between the rate of damage and the approach of cereal plots to tree blocks, and the density of ears per sampled square. A good decision on the position of cereal plots within farms seems tobe a priority to avoid sparrow attacks.

“…Sorghum is particularly important in difficult environments because of its strong ability to resist multiple abiotic stresses (Gilbert, 2009;Xie and Xu, 2019). Bird species known to consume sorghum include sparrow (Passer domesticus), parrot, pigeon (Columba livia), and Quelea quelea, among others (De Melo and Cheschini, 2012), and yield losses in sorghum caused by birds have been reported to reach as high as 52% (Kale et al, 2014). Moreover, there are few efficient control measures to protect field-grown crops from bird predation: bagging panicles and/or building anti-bird nets can require immense manpower and material investment.…”

Control of Bird Feeding Behavior by Tannin1 through Modulating the Biosynthesis of Polyphenols and Fatty Acid-Derived Volatiles in Sorghum

et al. 2019

Bird predation during seed maturation causes great loss to agricultural production. In this study, through GWAS analysis of a large-scale sorghum germplasm diversity panel, we identified that Tannin1, which encodes a WD40 protein functioning in the WD40/MYB/bHLH complex, controls bird feeding behavior in sorghum. Metabolic profiling analysis showed that a group of sorghum accessions preferred by birds contain mutated tan1-a/b alleles and accumulate significantly lower levels of anthocyanins and condensed tannin compounds. In contrast, a variety of aromatic and fatty acid-derived volatiles accumulate at significantly higher levels in these bird-preference accessions. We subsequently conducted both sparrow feeding and sparrow volatile attractant assays, which confirmed, respectively, the antifeedant and attractant functions of these differentially accumulated metabolites. In addition, the connection between the biosynthesis pathway of anthocyanin and proanthocyanidin and the pathway of fatty acid-derived volatile biosynthesis was demonstrated by discovering that Tannin1 complex modulates fatty acid biosynthesis by regulating the expression of SbGL2 in sorghum, thus affecting the accumulation of fatty acid-derived volatiles. Taken together, our study identified Tannin1 as the gene underlying the major locus controlling bird feeding behavior in sorghum, illustrating an example of the identification of an ecologically impactful molecular mechanism from field observation and providing significant insights into the chemistry of bird-plant ecological interactions.
