Assigning harvested waterfowl to geographic origin using feather δ2H isoscapes: What is the best analytical approach?
TL;DR: In this paper , the authors evaluated the strength of the relationships between δ2Hp values from three commonly used isoscapes and known-origin values three published datasets and one collected as part of this study, also grouping these data into foraging guilds.
Journal ArticleDOI
Birds of a feather don’t always flock together: variation in molt origins and movement patterns of winter finches in Ontario
TL;DR: Observed variation in breeding origins and movement patterns suggests each species employs a different migration strategy; therefore, future research and conservation efforts might be more beneficial if directed at individual species of winter finch.
Journal ArticleDOI
Stored fuel's importance for migrating monarch butterflies: Implications for conserving all migrant animals
TL;DR: Hobson et al. as discussed by the authors explored why stored fuel is critical to migrating animals, such as monarch butterflies, and pointed out that in times of current and predicted climate change, the added burdens of weather extremes add to the many threats facing migrants.
