Nissley and his team braved the Arctic’s freezing temperatures on Southampton Island in Canada’s north Hudson Bay to gain a better understanding of several factors that could have an impact on the declining population of the Atlantic brant, including where they nest for the summer and whether other geese species, whose populations are increasing, could be negatively impacting the brants’ nesting success.
