Resource partitioning between sympatric seabird species increases during chick‐rearing by Barger, Christopher P., Young, Rebecca C., Will, Alexis, Ito, Motohiro, Kitaysky, Alexander S.

“…Partitioning of resources by competing species of seabirds may increase during periods of food shortages and elevated energy demands. Here, we examined whether…”

An efficient method for sampling aerial arthropods at nest sites of an insectivorous songbird in steep decline by Haberski, Adam, Hagelin, Julie C., Barger, Christopher P., Sikes, Derek S., DuBour, Kristin A.

“…The decline of aerial insectivorous birds has been hypothesized to stem, in part, from a decline in aerial arthropod prey, underscoring the need for long-term…”
