Résumé :	Development of minimally invasive techniques to collect blood in free-living birds is desirable for both ethical and conservation reasons. We describe a new, simple technique for collecting blood samples from waterfowl eggs that involves recovering blood from a small hemorrhage after puncturing the shell of eggs showing the first signs of hatching. This technique allowed us to obtain a large number of blood samples from hatchling Greater Snow Geese (Chen caerulescens atlantica) and did not require the sacrifice or retention of any individuals, thus minimizing stress. High-quality blood samples for genetic Studies were obtained, with no adverse effects on either embryos or the post-hatch survival of young geese.
