Le but de cette Ligne directrice est de déterminer les effets sur la reproduction d'une substance administrée avec de la nourriture aux oiseaux. Des oiseaux sont alimentés par un régime contenant la substance d'essai à différentes concentrations pendant une période de moins de 20 semaines. Un minimum de trois concentrations alimentaires de la substance d'essai est exigé. La concentration maximum d'essai recommandée est de 1000 ppm. Les oiseaux peuvent être répartis dans les cages, soit en couple (au moins 12 cages par groupe d'essai), soit un mâle et deux ou trois femelles (au moins 8-12 cages par groupe) Les oiseaux sont amenés, par modification de la photopériode, à pondre des oeufs. Les oeufs sont rassemblés sur une période de dix semaines, artificiellement incubés et éclosent, et les jeunes sont élevés pendant 14 jours. Les équipements appropriés pour élever des oiseaux, de préférence en local clos, sont nécessaires. On observe la mortalité des adultes, la production d'oeufs, les oeufs fêlés, l'épaisseur de la coquille (au moins deux oeufs de chaque cage), la viabilité, l’éclosabilité et les effets sur de jeunes oiseaux pendant l'étude.

Today, according to the US Fish and Wildlife Service, more than fifty million Americans feed birds around their homes, and over the last sixty years, billions of pounds of birdseed have filled millions of feeders in backyards everywhere. Feeding Wild Birds in America tells why and how a modest act of provision has become such a pervasive, popular, and often passionate aspect of people's lives. Each chapter provides details on one or more bird-feeding development or trend including the "discovery" of seeds, the invention of different kinds of feeders, and the creation of new companies.

Les conventions internationales qui visent à combattre les problèmes d’environnement mondiaux -- communément appelées Accords multilatéraux sur l’environnement (AME) -- ont souvent recours, entre autres instruments, à des mesures commerciales. En fait, ce terme recouvre des dispositions diverses, qui vont de la simple notification des mouvements transfrontières à l’utilisation de sanctions commerciales imposées à un pays pour qu’il change de comportement en matière d’environnement. Le recours à de telles mesures dans le cadre des AME n'a pas été sans susciter des controverses dans les milieux responsables de la politique commerciale et de la politique de l’environnement. Pour démêler l'écheveau complexe de ces problèmes qui touchent tant au commerce qu'à l'environnement, la Session conjointe des experts des échanges et de l’environnement de l’OCDE a analysé l’utilisation de mesures commerciales à travers les exemples concrets qu'offrent trois AME adoptés par un grand nombre de pays : CITES (sur les espèces menacées d’extinction), le Protocole de Montréal (sur les substances qui appauvrissent la couche d’ozone) et la Convention de Bâle (sur les déchets dangereux). Si les études de cas révèlent, comme on pouvait s’y attendre, des expériences très diverses, certains problèmes et grands thèmes communs s'en dégagent, ainsi qu’une série d’enseignements ; ils sont synthétisés dans le dernier chapitre de ce volume.

International conventions designed to combat global environmental problems -- known as Multilateral Environmental Agreements or MEAs -- often use trade measures, among other instruments. But in fact the term trade measures covers a variety of provisions, ranging from simple reporting requirements of transboundary movements to the use of trade sanctions imposed to change a country’s environmental behaviour. MEA use of trade measures has not been without controversy in both trade policy and environment policy circles. In order to try and disentangle the various strands of this important set of trade and environment issues, the OECD Joint Session of Trade and Environment Experts focused on the actual experience with the use of trade measures in three universally subscribed MEAs -- CITES (on endangered species), the Montreal Protocol (on ozone layer depleting substances) and the Basel Convention (on hazardous wastes). Whilst the case studies unsurprisingly reveal varying experiences, common issues and main themes, as well as a series of lessons learned, could nonetheless be drawn together from the case study analyses and have been assembled in the concluding chapter of this volume.
