Fish and Wildlife Biologist | U.S. Fish and Wildlife Service, Ventura Field Office, Ventura, CA
May 2019 — Aug. 2019
Directorate Fellow | U.S. Fish and Wildlife Service, Attwater Prairie Chicken NWR, Eagle Lake, TX
Conducted a variety of monitoring projects related to the recovery of the endangered Attwater’s Prairie Chicken (APC). The main objective of the fellowship was to create a novel electronic system allowing data entry in the field to transfer directly to the refuge's existing Microsoft Access databases. These databases store data collected from captive-bred APCs when they are brought to the refuge for release. I validated the system by visiting captive breeding facilities to test the workflow while transporting birds that were ready for release. As a Directorate Fellow I was an integral part of the APC recovery effort, and the work I produced will aid in making future management decisions.
Various monitoring projects occur on the refuge during the summer, and I also was responsible for:
Monitoring locations of APC hens and their broods of chicks.
Collecting and process vegetation and insect samples.
Using radio telemetry techniques to track released APCs daily and collect location and mortality data.
Monitoring APCs awaiting release in acclimation pens on the refuge, and feeding the birds daily plus identifying signs of disease.

Influence of behavioral phenotype and fire history during pre-breeding, extra-territorial forays by yearling Florida Scrub-Jays (Aphelocoma coerulescens)
Investigated habitat selection by yearling Florida Scrub-Jays to test the hypothesis that pre-breeding jays direct their forays to areas with different time-since-fire (TSF) intervals to reduce competition and to potentially match habitat to their suite of behavioral attributes. I examined how preferences for habitat relative to TSF were influenced by a jay’s personality type and the TSF on its home territory. Fieldwork included playing territorial calls across a sampling grid and recording the identity of responding jays, and conducting behavioral trials to assess behavioral phenotype along a bold-shy axis. I found that yearling jays select either overgrown or optimal habitat, and that TSF of habitat used during forays is strongly predicted by home territory TSF.
2015
A GIS Framework for Quantitatively Mapping Songbird Territories
Using ESRI ArcGIS 10.2.2 I developed a geodatabase and associated tools for quantitatively mapping and analyzing songbird territories. To demonstrate the functionality of this methodology I incorporated data from more than 50 songbird censuses I conducted on a 30-acre study plot located in the southern portion of the Point Reyes National Seashore in Marin County, CA. The resulting outputs accurately reflected the shape and size of territories held by seven songbird species breeding within the study area.

Visualizing Shifting Mean Centers and Distributions of Avian Observations in Middle Tennessee
Using ESRI ArcGIS 10.1 and data from eBird (an online database of bird sightings) I mapped spatiotemporal variation in the distribution of bird sightings across eight middle Tennessee counties over 14 years. I created a geodatabase consisting of 64 feature classes to test the hypothesis that variation in the distribution of selected records from 2000 to 2014 corresponds to human population trends. By calculating (in two-year intervals) mean centers of coordinates associated with sightings of six focal species I determined directional shifts in the number of birds sighted over time using spatial analysis tools. I examined the following species:
Brown-headed Cowbird (Molothrus ater)
Carolina Wren (Thryothorus ludovicianus)
Downy Woodpecker (Picoides pubescens)
Mourning Dove (Zenaida macroura)
Northern Cardinal (Cardinalis cardinalis)
Yellow-rumped Warbler (Setophaga coronata)
TTU Campus Basemap and Geodatabase Project

Acquiring and attaching photographs of the fronts, sides, and entrances of campus buildings to their respective feature classes, as well as editing their attribute information
Gathering and incorporating data (e.g., building names, addresses, number of floors, etc.) into the geodatabase
