Vocalizations Of Adult American Kestrels (falco Sparverius): Effect Of Breeding Stage, Sex, And Context On Call Use And Characteristics
… uttered by males and females during different breeding stages and different behavioral contexts. In addition, I conducted playback experiments using the whine, chitter, and klee calls, and presentation experiments with models (study skins) of conspecifics and potential nest predators (human). I …

The causes and consequences of variation in the cloacal microbiome of tree swallows (Tachycineta bicolor)
… microbiome diversity vary with host age or breeding stage? Are there fitness consequences associated with differences in reproductive microbiome diversity? To explore these questions, I studied tree swallows (Tachycineta bicolor), a socially monogamous bird in which both females and males …

Plasticity and partitioning of foraging behaviour among and within sympatric Pygocelis penguin populations
Central-place foragers, such as breeding seabirds, need to adjust their foraging behaviours in response to the growth and development of their offspring. As a result, they need to return to their nests regularly. These breeding constraints limit their foraging ranges. In the Southern Ocean, …

Validating Body Condition Indices As Indicators Of Individual Quality: Does Condition Explain Intraspecific Variation In Reproductive Success And Survival Among Crimson Finches (Neochmia Phaeton)?
… for reproductive success and survival over four breeding seasons. My study population is well suited for this research because individuals forage in common areas and do not hold territories such that variation in condition between individuals is not confounded by differences in habitat quality. …

Piping plover habitat and demography following storm-induced and engineered landscape change
… survival of plover broods. We evaluated whether breeding stage (pre-breeding, nesting, brooding, post-breeding), simple breeding stage (breeding, not-breeding), or instantaneous behavior class (parental, non-parental) best explained habitat selection during the 5-month plover breeding season. We …

Factors Associated with Space Use and Reproductive Success of American Kestrels in Northern Virginia, USA
Understanding how breeding-season space use varies across individuals and landscapes can provides insight into the resource requirements of species. My thesis evaluated the space use of American kestrels (Falco sparverius), a species of conservation concern, and tested whether their movement …
