dr. momorrissey's s study is the first to look into this issue in canada. >> we have a field study that's trying to understand how neonicotinoids potentially get into wetlands and whether or not they affect aquatic invertebrates, which are the base of the food chain for all kinds of other wildlife species, and in particular, birds. so we're trying to link these 3 different things, um, from the--from the pesticide on the field to the wetlands to the bugs, and ultimately to the birds.s. we've found that neonicotinoids across the board have a range of toxicity for the different insect species. but for a certain group, and particularly the mayflies and the midges, these species are extremely sensitive to neonicotinoids. >> the chicks, the young birds, need that supply of insects. as do the, uh, the female birds, the hens, when they're laying their eggs. they need that high protein source. and there's some critical points in birds' life where insects are key and critical.l. and if the--t-the amount, the availability of insects is reduced, it has been shown that that affects reproduction. >> so
