“…This is also supported by our estimation of surface seeds in fields. However, it is acknowledged that some birds dehusk seeds and that this behaviour is mainly observed in small species (body weight < 50 g) and chiefly in the specialized granivores (finches, sparrows and buntings) (Avery et al 1997; Prosser and Hart 2005), Thus, the ingestion of imidacloprid together with the consumption of treated seeds may be reduced by this behaviour for small granivorous farmland birds.…”

The large-scale use of neonicotinoid insecticides has raised growing concerns about their potential adverse effects on farmland birds, and more generally on biodiversity. Imidacloprid, the first neonicotinoid commercialized, has been identified as posing a risk for seed-eating birds when it is used as seed treatment of some crops since the consumption of a few dressed seeds could cause mortality. But evidence of direct effects in the field is lacking. Here, we reviewed the 103 wildlife mortality incidents reported by the French SAGIR Network from 1995 to 2014, for which toxicological analyses detected imidacloprid residues. One hundred and one incidents totalling at least 734 dead animals were consistent with an agricultural use as seed treatment. Grey partridges (Perdix perdix) and “pigeons” (Columba palumbus, Columba livia and Columba oenas) were the main species found. More than 70% of incidents occurred during autumn cereal sowings. Furthermore, since there is no biomarker for diagnosing neonicotinoid poisonings, we developed a diagnostic approach to estimate the degree of certainty that these mortalities were due to imidacloprid poisoning. By this way, the probability that mortality was due to poisoning by imidacloprid-treated seeds was ranked as at least “likely” in 70% of incidents. As a result, this work provides clear evidence to risk managers that lethal effects due to the consumption by birds of imidacloprid-treated seeds regularly occur in the field. This in turn raises the question of the effectiveness of the two main factors (seed burying and imidacloprid-treated seeds avoidance) that are supposed to make the risk to birds negligible. Risk factors and the relevance of mitigation measures are discussed.Electronic supplementary materialThe online version of this article (doi:10.1007/s11356-016-8272-y) contains supplementary material, which is available to authorized users.

“…The U.S. Department of Interior's National wildlife medical institution reported that fifty of the documented cases of lethal poisoning of birds are caused by ops and CMs (Madison, 1993). The possible route of exposure of these pesticides is the consumption of seeds or insects contaminated on their surface with lethal amounts of pesticide (Prosser and Hart, 2005). Organophosphates are involved in 335 separate mortality events inflicting the deaths of about birds in the USA between 1980 and 2000 (Fleischli et al, 2004).…”

Contaminants in Agriculture and Environment: Health Risks and Remediation

View full text Add to dashboard Cite

Avifauna is one of the successful diverse and evolutionary groups and occurs in the tropics in large numbers as compared to temperate zone. Fluctuation in the diversity of birds provides early warning of environmental problems. The threats to their community structure due to various reasons. Agricultural pesticides have been shown to affect 87 percent of the bird species that are threatened globally. Over the past four decades, many farmland avian species have shown alarming declines in numbers and/or range. Approximately five million plenty of pesticides are used annually in the world, of which about seventieth is used for agriculture causing decline in avian population in the agro-agriculture ecosystem. In this review an attempt has been made to focus on the effects of pesticide applications on birds. The possible health effects of pesticide applications on avifauna has been discussed as well.

Exposure of farmland birds to pesticides: a need for data Knowledge of bird exposure is an essential preliminary step to further investigate the overall potential impact of pesticides on avian reproduction (Engelman et al, 2012;Prosser and Hart, 2005).

Estimating exposure of wild birds to plant protection products is of key importance in the risk assessment process evaluating their harmful potential. In this paper, we propose an ecologically-relevant methodology to estimate potential exposure to active substances (ASs) of a farmland focal bird, the gray partridge Perdix perdix. It is based on bird habitat use of fields at the time of pesticide applications. It accounts for spatio-temporal heterogeneity at population and landscape scales. We identify and quantify the potential exposure to 179 ASs of 140 clutches during pre-laying, laying, and incubation phases, and of 75 coveys. The data come from a large scale field study combining radiotelemetry and a farmer survey. They were collected in 12 different representative sites. The proportion of clutches potentially exposed to a given chemical was ≥5% for 32 ASs; prothioconazole and epoxiconazole ranking first. 71% of clutches were potentially exposed to ≥1 AS and 67% to ≥2 ASs. Mixtures involved 2 to 22 ASs. They emerged from commercial formulations, tank mixtures, bird habitat use, and combinations. ASs were fungicides (53%), herbicides (25%), and insecticides (16%) used on a variety of crops in April-June, when ground-nesting birds are breeding. The European Food Safety Authority conclusions report a long-term first-tier toxicity-to-exposure ratio (TERlt) <5 for 11 out of 19 documented ASs, and higher-tier TERlt <5 for 5 out of 10 ASs. This suggests a potential risk for bird reproduction in farmlands. Globally 13% of coveys were potentially exposed to 18 ASs during the first month (1-4 coveys per AS). The use of our field data in future research and risk assessment is discussed.
