Dominance And Aggression Among Hummingbirds In The Cloud Forests Of The Talamanca Mountains, Costa Rica, Crystal Sauder, Aileen Scarim Apr 2019

Dominance And Aggression Among Hummingbirds In The Cloud Forests Of The Talamanca Mountains, Costa Rica, Crystal Sauder, Aileen Scarim

Scholar Week 2016 - present

Hummingbirds (Trochilidae) are known for being aggressive and territorial. By knowing hummingbirds are not very social, nor appear to enjoy having interactions with others, we wanted to observe how multiple species of Trochilidae interact with one another. The study was completed to observe if males of different Trochilidae would be more aggressive at hummingbird feeders over females. Three different feeder locations were decided on, spread across the Savegre Valley region near the Quetzal Education Research Center (QERC). Symbols were agreed upon in order to shorthand the exact series of events that were happening while we observed the feeders. Species and ...


Food Preferences Of Red-Headed Woodpeckers (Melanerpes Erythrocephalus) And The Relationship With Season Change, Crystal Sauder Apr 2019

Food Preferences Of Red-Headed Woodpeckers (Melanerpes Erythrocephalus) And The Relationship With Season Change, Crystal Sauder

Scholar Week 2016 - present

Red-headed woodpeckers (Melanerpes erythrocephalus) used to be easy to find out in the wild, but as humans encroached on their habitats, their populations started to become impacted. They have a habitat range from Southern Canada down to the Gulf Coast. In several states their numbers are threatened due to loss of habitat. Red-headed woodpeckers prefer to live in open woodlands with dead, or dying, trees to nest in. As humans take away the dead trees from the forests, red-headed woodpeckers are losing their nesting sites. Preservation of red-headed woodpecker habitats are needed to ensure the population starts to grow, and ...


Effects Of Environmental Enrichment On Behavior In A Domestic Goat Herd, Stephanie Peramas May 2018

Effects Of Environmental Enrichment On Behavior In A Domestic Goat Herd, Stephanie Peramas

Senior Honors Projects

Animal welfare is one of the most important parts of animal management. Apart from other measures of good animal welfare, like being in good health, animal behavior can be indicative of the animal’s internal state and is often one of the first signs of improper welfare. Stereotypies, or stereotypic behavior, are commonly viewed as a symptom of improper animal welfare. Unenriched, or barren, environments associated with farmed livestock have long been associated with inducing stereotypic behavior. The addition of precise enrichment to the animals’ environment is a common remedy for stereotypic behavior. With respect to stereotypic goat behavior, few ...


Emergence Of Zoos In The U.S. And A Search For The Exotic, Austin M. Hutchinson Apr 2018

Emergence Of Zoos In The U.S. And A Search For The Exotic, Austin M. Hutchinson

Student Scholar Showcase

The emergence of zoos in twentieth century America had many factors that contributed to their mission, success, and overall exotic nature. Zoos have been a part of human civilization for centuries, but it would not be until 1876 when the first zoo would appear in the United States. Individuals craved excitement and the use of exotic animals from all over the world became an important component of what zoos would become. This era coincides with the European colonization of Sub-Saharan Africa, known as the Scramble for Africa. Animals were brought from the so-called “Dark Continent” to be put on display ...


Does Recreational Diving Impact Hawksbill Sea Turtle Sighting Rates? Preliminary Analysis For A Marine Protected Area, Honduras, Christian Hayes, Dustin S. Baumbach, Marsha K. Wright, Linda Baeza, Marta Macpui, Lidia A. Salinas, Stephen G. Dunbar Aug 2017

Does Recreational Diving Impact Hawksbill Sea Turtle Sighting Rates? Preliminary Analysis For A Marine Protected Area, Honduras, Christian Hayes, Dustin S. Baumbach, Marsha K. Wright, Linda Baeza, Marta Macpui, Lidia A. Salinas, Stephen G. Dunbar

Stephen Dunbar, PhD

Recreational diving is a form of ecotourism that is traditionally viewed as an ecologically sustainable activity prompting increased awareness for the marine environment. Still, recent studies indicate that recreational diving may cause increased spatio-temporal variability within coral ecosystems and unintended behavioral changes in marine macrofauna. Few studies however, have looked specifically at the effect of recreational diving on sea turtles. The purpose of this study was to determine if differences in dive site use and habitat composition can affect the rate of Hawksbill sea turtle (Eretmochelys imbricata) sightings in a marine protected area. From June 3 – August 31, 2014 we ...
