Offspring Retrieval Behaviors After Brood Loss In The Convict Cichlid, Heather Witherspoon Govert Jan 2015

Offspring Retrieval Behaviors After Brood Loss In The Convict Cichlid, Heather Witherspoon Govert

Online Theses and Dissertations

Parents provide care for their young in several different ways. One of these is searching for and retrieving any young that may become displaced from their nest. In monogamous biparental species, parents may share care of their young, including retrieval efforts. Convict cichlids (Amatitlania siquia) are an example of a monogamous biparental fish that show shared parental care of young. In the wild, these cichlids defend nests and search for missing young in response to complete or catastrophic brood loss. This retrieval behavior is important for both parents because parents, especially the males, have been observed to abandon their mate …

Effects Of Supplemental Food On The Behavior, Aggression, And Paternity Status Of Male Indigo Buntings (Passerina Cyanea), Bradley Mcleod Jan 2015

Effects Of Supplemental Food On The Behavior, Aggression, And Paternity Status Of Male Indigo Buntings (Passerina Cyanea), Bradley Mcleod

Online Theses and Dissertations

Breeding is an energetically costly activity for birds. If energy-limited, birds may alter their time budgets, reducing time spent in some activities and spending more time in others. To date, no experimental study has investigated the possible effect of food availability on male mate guarding behavior. Additionally, previous results from food supplementation studies are mixed. My objectives were to determine how food supplementation might influence the breeding behavior of male Indigo Buntings (Passerina cyanea). I predicted that, compared to non-supplemented males, food-supplemented males would: 1) spend less time foraging, 2) spend more time singing, 3) spend more time mate guarding, …

Flight Vocalizations And Displays Of Adult Chimney Swifts (Chaetura Pelagica): Description And Function, Louise Ann Peppe Jan 2015

Flight Vocalizations And Displays Of Adult Chimney Swifts (Chaetura Pelagica): Description And Function, Louise Ann Peppe

Online Theses and Dissertations

The vocalizations of many songbirds have been well documented and analyzed, but less is known about the vocal behavior of many non-passerines, including swifts. While flying alone as well as during aerial displays with conspecifics, Chimney Swifts (Chaetura pelagica) often utter a twitter call consisting of a series of high-frequency chip notes. However, little is known about the possible function(s) of swift flight displays and their twitter call. My objectives were to record, analyze, and document the aerial behaviors and associated vocalizations of adult Chimney Swifts. I studied swifts at the Blue Grass Army Depot in Madison County, Kentucky, where …

Reproductive Biology Of Syntopic Blackside Dace And Southern Redbelly Dace In Two Kentucky Streams, Brajaan Hayes Jan 2015

Reproductive Biology Of Syntopic Blackside Dace And Southern Redbelly Dace In Two Kentucky Streams, Brajaan Hayes

Online Theses and Dissertations

When a rare endemic species and an ecologically similar, but more cosmopolitan species share habitat, understanding how they interact with each other is important for conservation efforts. This is especially true if both species rely on the same spawning habitat, which could potentially lead to competitive displacement or hybridization. It is known that the federally threatened Blackside Dace and common Southern Redbelly Dace are ecologically similar species, occur syntopically in Kentucky in the upper Cumberland River basin, and utilize some of the same host species for nest sites; however, it is unclear if the two fish species are spawning site …

Fate Of Captive-Reared Bobwhite Quail Released In Central Kentucky, Adam Carter Jan 2015

Fate Of Captive-Reared Bobwhite Quail Released In Central Kentucky, Adam Carter

Online Theses and Dissertations

The fate of pen-raised bobwhite quail (Colinus virginianus) released onto two farms (Site 1 and 2) and a reclaimed coal surface mine (Site 3) in south-central Kentucky during the summers of 2008 and 2009 was assessed. Of the 57 bobwhite quail radio-tagged and released in this study, the fate of 26 (45%) was unknown because the telemetry signal was lost and the birds could not be located. Within 34 days after release, mortality of the remaining 31 radio-tagged birds was 100%. Raptors, coyotes, and mesomammal predators were responsible for most (84%) of the identified quail mortality; accounting for the deaths …

Effect Of Variation In Nestling Hunger Levels On The Begging Behavior Of Nestlings And The Provisioning Behavior Of Adult American Kestrels, Katheryn Ann Watson Jan 2015

Effect Of Variation In Nestling Hunger Levels On The Begging Behavior Of Nestlings And The Provisioning Behavior Of Adult American Kestrels, Katheryn Ann Watson

Online Theses and Dissertations

Little is known about how variation in nestling begging intensity influences the behavior of adult raptors and how responses of adult males and females to such variation might differ. My objective was to manipulate the begging intensity of nestling American Kestrels (Falco sparverius) and examine the responses of adult males and females. I studied 12 pairs of kestrels nesting in nest boxes from 1 March to 1 July 2014 at the Blue Grass Army Depot, Madison County, Kentucky. Nest boxes were modified with a separate compartment for a camcorder to record nestling behavior, and a second camcorder was placed outside …
