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 …

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 …
