Pesticides Make Migrating Birds Lose their Way

Guest Blog post by Dr. Bridget Stutchbury

Pesticides are widely recognized as a risk to birds that forage in agricultural environments especially during migration. Since many current use insecticides are potent neurotoxins, we speculated that they could have behavioural effects in small songbirds landing in agricultural fields during their journey north if they consume tainted seeds or granules when they stop to fuel.

So we designed a study to test whether low level exposure to 2 widely used insecticides – imidacloprid  (a neonicotinoid) and chlorpyrifos  (an organophosphate) could disrupt the migratory ability of a wild-caught songbird. White-crowned sparrows, a common seed eater, were captured on migration and held in captivity at the Facility for Applied Avian Research at the University of Saskatchewan. After acclimation, we exposed the birds to either a low or high dose of either imidacloprid or chlorpyrifos at concentrations they could realistically encounter in the environment, and tested their orientation in a series of Emlen funnel migration trials before dosing, during the 3 day exposure, and during the recovery period.

What surprised us was how sensitive and rapid the effects were, particularly to imidacloprid.

The birds showed a significant loss of body mass and signs of acute poisoning (lethargy and loss of appetite). The migration trials also showed that birds completely failed to orient or changed their northward orientation, whereas controls continued to behave as expected.  While the chlorpyrifos treated birds did not show toxicity in terms of weight loss, they too lost their migratory orientation.   In the wild, we calculated that these effects would be seen if the birds consumed just a few treated seeds or granules mistaken as grit.

We were encouraged that most birds survived, and could recover following the cessation of dosing, but the effects we saw were severe enough that the birds would likely experience migratory delays or changes in their flight routes that could reduce their chance of survival or cause a missed breeding opportunity.

Since these chemicals are used over vast areas of North America and the timing of application directly overlaps with spring migration, the results of this study raises serious concern about the risk of increasing use of seed and granular pesticide treatments to millions of migrating songbirds.

The Ortolan Bunting Will Finally Be Off the Menu in France!

 “We have won our battle against Ortolan Bunting trapping and the phenomenon is basically wiped out from Les Landes.”

 THE MESSENGER took audiences into the fields of Les Landes, in south-west West France, to witness the illegal hunting of Ortolan Bunting, a practise that was decimating local populations.  Now, the Ortolan Bunting will finally be off the menu in France!  No other European songbird has declined as rapidly in recent years, with an overall decline of 84% since 1980 due to poaching and intensive agriculture – this, despite hunting of the species being forbidden by French law since 1999 when it became a protected species.   Because the Ortolan dish is considered a cultural tradition, authorities had often turned a blind eye to the activities of poachers.

For the past 10 years, LPO (League for the Protection of the Oiseaux) the BirdLife International partner in France has been fighting this illegal practice on the ground, and also in the air, where alongside CABS (Committee Against Bird Slaughter), they have been identifying trapping sites and releasing the birds, before alerting the authorities. Until recently, these interventions were the only way to identify and prosecute the poachers, who operated with the blessing of local elected officials and hunting officials, and who claimed that the state “tolerated” these practices. Indeed the authorities wouldn’t file charges for installations of 30 traps or less. More on the practise and new developments in this article from Bird Life International.  

The French Ministry of the Environment requested  guidelines to study the Ortolans on a continental scale. 

Frédéric Jiguet from Museum National D’Histoire Naturelle in Paris, (featured in The Messenger) partnered with other scientists from more than 12 countries across EU to conduct the study.  He also worked in partnership with ONCFS (French Hunting & Wildlife National Office).  

REVBanner-KeyMsg-2F-Jiguet-Quote

Frédéric Jiguet and his colleagues research work helped convince French Ecology Minister, Nicolas Hulot, to call for a definitive end to the hunting.  This was followed up in the field with a high pressure from the police this past fall, so there are now very few poachers.

The main conclusions are that the numbers migrating by south-west France are estimated on average   only 81,000 pairs (300,000 individuals including juveniles), with a recent decline estimated between -20% and -30%, while the overall trend of birds using the western flyway, or the eastern flyway, is a decline of lower amplitude estimated between -10% and -20%. The birds flying by south-west come mainly from Poland (probably 75%), the others coming mainly from Germany and Sweden, and also from Norway (where there are only astonishingly only 10 breeding pairs left) – so almost only from EU countries.   The first pages of the report are a summary of overall results, then detailed parts on each techniques.  (genetics, isotopes, geolocators).

The Messenger Takes Flight in the UK!

SongbirdSOS Productions Inc. and  Films à Cinq are pleased to announce that our award-winning feature documentary THE MESSENGER directed by Su Rynard is taking flight in the UK.  It is being released into UK cinemas, starting October 26th.   This cinematically beautiful and poignant documentary is essential viewing for anyone who cares about the environment and nature.  THE MESSENGER explores mankind’s deep-seated connection to the world’s songbirds and the devastating impact humans have had on bird species. It is an enlightening introduction to the global scientific research being done to further bird conservation.  The release of the film is timely, as more than a quarter of the UK Birds are in serious decline. * 

The UK tour of THE MESSENGER starts at Purbeck Film Festival in Wareham October 26, before travelling to Nottingham, Oswestry, Suffolk, Manchester and Liverpool.

On her drive to make the film director Su Rynard commented, “Birds are our ‘early warning system’ and this was one of the inspirations behind the film. Since ancient times we have looked to birds to foretell the future. Changes in the flights or songs of birds can signal the coming of storms, the change of season, or the dawn of a new day. A decline in the numbers or health of birds points to changes in the environment. Now is a critical time for the world’s climate and ecosystems. Birds have something to tell us, and I wanted to amplify their message.”

Screenings will feature guest hosts, including the Wildlife Trust and the RSPB.

Bird & Wild, a Bird Friendly coffee company is providing goodie bags at select screenings.  Bird & Wild is one of the UK’s only Smithsonian certified Bird Friendly® coffee roasters and it is on a mission to help protect migrating birds and support the RSPB, while offering triple certified, great tasting Fairtrade organic coffee, one cup at a time.

Canadian producer Joanne Jackson says ” We are excited to be working with Nottingham based PIPOCA for the UK release. Sally Hodgson from PIPOCA has tremendous experience releasing films that make an impact with audiences.  We believe THE MESSENGER will find an enthusiastic audience in the UK, because as any committed ‘twitcher’ or nature lover will attest, the sport of Birdwatching is a very popular past-time in the UK.”
