Using Light-Level Geolocation to Investigate the Carry-Over Effects of Long-Distance Migration on the Reproductive Success of Dunlin (Calidris Alpina Hudsonia)
Avian migration strategies can have lasting effects on individual fitness in subsequent seasons. These carry-over effects are difficult to study in migratory species because of the geographical separation between breeding and non-breeding sites. I used light-level geolocation to examine, for the …

When the Map Fails the Territory: Hidden State Models, Complex Traits and the Evolution of Bird Migration
… datasets (Chapter ref{ch:1}). Taking bird migration as an example of a hard-to-measure complex trait, I then develop new continuous metrics of bird movement from large-scale community science (eBird) data, using entropy-based measures and phylogenetically aligned component analysis (PACA) …

The nocturnal flight calls of migratory songbirds: interspecific variation in the “zeep” complex and intraspecific variation across North America
… short vocalizations, produced primarily during migration. Although these calls offer a unique opportunity for studying avian migration, there has been little research into many aspects of these calls, such as the species-specificity of the calls of closely related taxa, or variation in calls …

Holocene guano influences on eutrophication and lacustrine ecology at Kettle Lake, North Dakota
… the response of these systems to both future avian influence and climate variability. Here, I examine the influence of climate-forced avian migration on nitrogen cycling at Kettle Lake, North Dakota throughout the Holocene. I investigate this influence using stable nitrogen isotope values …

Migratory Stopover of Songbirds in the Western Lake Erie Basin
… migrants to minimize time and energy spent in migration and maximize fitness. Migrants should therefore attempt to select stopover habitat that affords them suitable safety, shelter, and food. A better understanding of habitat attributes that support high numbers of migrant landbirds during …
