Behavioral Observations: Foraging And Aggression Of Neotropical Migrants And Resident Birds In Panama, Jessica M. Johnston, Samuel B. King, Ryan A. Levering
Behavioral Observations: Foraging And Aggression Of Neotropical Migrants And Resident Birds In Panama, Jessica M. Johnston, Samuel B. King, Ryan A. Levering
Rice Rivers Center Research Symposium
Lyons suggests that foraging data in songbirds can be an indicator of food abundance, with higher attack rate= higher habitat quality; higher foraging speed= lower habitat quality (2005). Territorial behavior such as interspecific aggression among songbirds may also be related to food availability. Previous studies have documented variation in the extent of territorial and aggressive behaviors among resident and Neotropical migratory species on tropical wintering grounds. This research gathered foraging and aggression data at two coastal angroves sites in central Panama, one on the Caribbean Coast (Galeta) and one on the Pacific Coast (Juan Diaz-East). Foraging data was used an …
Stopover Decisions Of Migratory Shorebirds: An Assessment Of Habitat Use, Food Availability, Behavior And Phenology, Ryan Stutzman
Stopover Decisions Of Migratory Shorebirds: An Assessment Of Habitat Use, Food Availability, Behavior And Phenology, Ryan Stutzman
School of Natural Resources: Dissertations, Theses, and Student Research
Habitat loss and alteration from land use change, species invasion, and more recently, climate change has reduced biodiversity and ecosystem function worldwide. Habitat decisions have important implications to individual fitness as well as population dynamics and community structure. Resource limitation, predation, competition, and unfavorable abiotic conditions all have the potential to influence survival and future reproductive potential. Understanding how changes to ecosystem structure and function impact species and populations of conservation concern is essential for conservation delivery to be effective. Similar to many migratory species, shorebird populations are declining worldwide and declines may be related to the loss of important …
Population Dynamics, Chick Diet, And Foraging Behavior Of The Razorbill (Alca Torda) At Matinicus Rock, Maine, Katherine E. Kauffman
Population Dynamics, Chick Diet, And Foraging Behavior Of The Razorbill (Alca Torda) At Matinicus Rock, Maine, Katherine E. Kauffman
Masters Theses 1911 - February 2014
During the summers of 2007-2009, I studied the population growth and reproductive and foraging ecology of the Razorbill (Alca torda) at Matinicus Rock (MR), Maine. This medium-sized marine bird in the family Alcidae (auks) was extirpated from the Gulf of Maine in the late 19th century by hunting, collecting, and colony disturbance. Following legislation protecting seabirds and their nesting habitats, the Razorbill has recolonized probable former nesting habitat in the Gulf of Maine during the past several decades. Six small colonies comprise the Maine population, which is listed as threatened and forms the southern extension of the …
