“…Schafer et al (1983) also demonstrated an avoidance of 1.0% thiram by passerines. Treating seeds with thiram (0.5%), however, did not reduce house crow (Corvus splendens) damage to sprouting sunflowers (Dhindsa et al, 1991). Whether the difference in the extent of seed protection among these studies reflects bird species tested, thiram concentrations, treatment conditions, or a combination of these and other factors is unknown.…”

Direct seeding is a potential method for reforestation of pines on many southern sites. The success of direct seeding, however, depends, at least in part, in reducing seed predation by birds and rodents. We conducted a series of tests to assess the efficacy of' capsicum and thiram in reducing mouse damage to longleaf pine (Pinus palustris) seeds. House mice (Mus musculus) predation was reduced (P < 0.05) by treating seeds with either capsicum or thiram or a mixture of the two ingredients. Deer mice (Peromyscus nranicufutus) avoided seeds treated with a mixture of capsicum and thiram. We conclude that the capsicum and thiram mixture should be pursued as a potential repellent to protect longleaf pine seeds from animal predation when these seeds are used in direct seeding efforts to establish southern pine forests.

“…Bird damage to crops has been reported worldwide: in European countries, America,, Africa and Asia . In German agriculture, damage to seeds and seedlings up to the four‐leaf stage of maize ( Zea mays L.) and other crops is mainly caused by pheasants ( Phasianus colchicus ), corvids and pigeons , .…”

Bird damage to seeds and seedlings of corn and other crops is widespread in organic farming because no adequate seed protection is available. In this study we systematically tested the effect of seed treatments with three synthetically-produced substances known to affect bird feeding behavior (anthraquinone, pulegone and methylanthranilate) in different concentrations. There was no negative effect on the germination of seeds for all seed treatments. Their repellent effect was tested by food and seedling choice (treated versus untreated) experiments with pigeons (Columba livia) in aviaries. The best treatment variants in these trails were additionally tested regarding plant growth in the field where wild birds had unlimited access.In aviaries, untreated seeds were clearly preferred over treated seeds by pigeons. The highest feeding deterrence effect occurred with the treatment variants 7.5% pulegone and 0.5% methylanthranilate. In these cases less than 5% of the daily consumption was treated seeds. In contrast, however, there was no treatment effect on seedlings. The same number of seedlings grown from treated and untreated seeds remained intact.Further replications and field experiments with additional treatment variants are being conducted at the moment. The repellent effects of some of the treatment variants indicate that further studies with the same compounds but based on plants and benefit-cost-analyses should be done to yield a bird repellent to be used for organic seed protection.

House crows (Corvus splendens) have become well-established in Ismailia Governorate, Egypt, where they pose several and serious impacts on native biodiversity, ecosystems and humans health. However, there is a lack of literature on the status and effects of invasive birds in Egypt. Over the past 10 years in Ismailia, House crow have increased at a rate approaching (60000 birds) 15% per annum; if this were allowed to continue, the population now 10909 birds and will exceed more by 2014, probably accompanied by an increase in geographical distribution in all Suez canal regions and an exacerbation of the problems caused. Population control is recommended, involving improvements in urban hygiene and the capture of adult crows using stupefying baits. Suitable baits and stupefacient doses were identified and these should be used annually, just before the breeding season. Control should be accompanied by studies of relevant aspects of the biology of house crows in Ismailia Governorate.  Index Terms-environmental impact, non-native invasive species, house crow birds, risk management, ismailia-egypt
