Assessment of presence and impacts of endocrine disrupting chemicals in an obligate riparian songbird, the Louisiana Waterthrush, in areas of high-intensity hydraulic fracturing

This project involves collaborative research between me, Dr. Chung-Ho Lin, University of Missouri, Columbia, Dr. Steve Latta, The National Aviary and Mack Frantz and Dr. Petra Wood, West Virginia University. This research follows on the heels of our previous research, (Latta et al. 2015), which identified the presence of heavy metals associated with hydraulic fracturing that had bioaccumulated in the feathers of Louisiana Waterthrushes in fracking areas in the Fayetteville and Marcellus Shale Plays. During field research, we found suspiciously low reproductive success associated with small clutch size, eggs that did not hatch, and nestlings which did not thrive in birds located in fracking areas. Low reproductive success was a result of small clutch sizes, eggs that did not hatch, and nestlings which did not thrive. We believe that this may be tied to endocrine disrupting chemicals also seen in conjunction with hydraulic fracturing. Samples of feathers, eggs, and aquatic insect prey taken from areas of hydraulic fracturing and areas that served as controls are currently being testing using new methodologies created by Dr. Lin that allow for the testing of relatively light samples (feathers) for organic compounds including the endocrine disrupting chemicals as well as associated metabolites.

Effects of lunar illumination and weather on Eastern Screech-Owl, Otus asio, vocal activity

Eastern Screech-Owls (Megascops ) are nocturnal, cryptic, and difficult to detect. Broadcasts are effective for detection with consideration of moon phase, weather, and threat of predation. Reports of influence of these variables are contradictory. Our objective was to determine if luminance, the sensory perception of brightness, not previously used to predict Eastern Screech-Owl activity, was also an influential variable. Luminance was measured with a night sky brightness photometer (mag/arcsec2) along with moon phase, temperature (oC), % humidity, wind speed (mph), % cloud cover, and background noise (dB). Broadcasts of Eastern Screech-Owls were followed by broadcasts of Barred (Strix varia) and Great Horned Owls (Bubo virginianus) to determine if their presence restricted Eastern Screech-Owl response activity. Principal Components Logistic Regression (PCLR) was used to create models of best predictors. Responses were predicted by luminance, season, wind speed, and presence of Great Horned Owls. Luminance predicted Eastern Screech-Owl activity with vocalizations declining when forest became darker with peaks of response activity clustered between periods of higher and lower luminance values near a ratio of open sky to forest luminance of 0.94:1. Great Horned Owl presence resulted in a decline in Eastern Screech-Owl activity, but presence of Barred Owls did not. The lack of influence of Barred Owl presence on Eastern Screech-Owl activity along with increased frequency of response with breeding season may illustrate trade-offs between predation and predator avoidance.asio

Investigation of huddled pair roosting and associated vocalizations and behavior of pair-bonded Carolina Wrens, Thryothorus ludovicianus

The objective of this undergraduate research study is to observe and quantify roosting behavior of mated pairs of Carolina Wrens through the non-breeding season and to ascertain the function of accompanying vocal communication and to determine gender differences. Additionally, we will determine if correlations exist between huddled pair roosting, ambient temperature, and weather patterns. Methods will include techniques in bioacoustics and RFID technology. Leg bands carrying a lightweight passive integrated transponder (PIT) tag will be placed on each member of a mated pair and a roosting box placed within each pair’s territory. An antenna will be aligned to the entry of each roosting box and an RFID reader affixed to the bottom of the roosting box where it will collect data on the timing of movement of the pair in and out of the box along with hourly data on ambient temperature. Climate data will be collected via a local NOAA station. Motion-activated cameras will be used to determine the accuracy of RFID readings.

This research will establish a banded population of Carolina Wrens for future student research projects regarding mating and territorial behavior, sexual size dimorphism, winter morbidity, and daily time budgets. Data collected will be compared to a collaborator in research, Dr. Maureen McClung, at Hendrix University in Central Arkansas and with data collected previously at more northerly latitudes of the Eastern United States. We predict winter mortality will play a more critical role in the life histories of those populations as compared to the population in the bird’s southern-most range in Louisiana.con-current study of life history information of populations of Carolina Wrens with

Annual monitoring and maintenance of a banded population of avian obligate riparian and riverine indicators of ecological integrity

I have banded four hundred fourteen Louisiana Waterthrushes within the upper watershed of the Buffalo National River in the years 2005-2017. This active banded population is followed from year to year to determine the health of the population and their response to environmental changes within the watershed of the national park. The objectives of this project are to continue to maintain a banded population of Louisiana Waterthrush through annual banding attempts and to monitor these populations on streams within the Buffalo National River watershed as a continuation of my research and to make the population available to other researchers, students, and citizen scientists with an interest in the species and their environment. Also, researchers will be able to quantify stream health through of the number of waterthrush territories found along the stream and waterthrush site fidelity to streams (Marshall, 2012). I believe the continuation of this long-term project will be important in providing greater understanding of this and other riparian species and the requirements for conservation of their habitat in a rapidly changing environment. census

Elucidation of fall migration patterns of Northern Saw-whet Owls (Aegolius acadicus) in the Southeastern United States

The Northern Saw-whet Owl, Aegolius , is a boreal species known to show irruptive migration patterns. Little is known about the migratory patterns of the saw-whet owl in the southeastern United States, but they are documented to have moved as far south as Alabama, Louisiana, and Northern Florida. I joined colleagues Dr. Kimberly G. Smith and Mitchell Pruitt in Northwest Arkansas, Dr. Mia Revels in Northeastern Oklahoma, and Dana Ripper in Central Missouri in creating a series of south-central and south-eastern banding stations, Smith et al. 2017, to determine if the Northern Saw-whet Owl will migrate to and through our respective regions. This work coincides with and supports Dr. D.F. Brinker and his colleagues (www.projectowlnet.org) who have created Project Owlnet to maintain a national cooperative research effort to determine migratory owl movements. This knowledge gained from our study will be added to that of this nationally ongoing project to further elucidate the migratory habits of the Northern Saw-Whet owl along with information including distances traveled from boreal home ranges and additional supporting information for age differentiation among migrants. Elucidation of the migration of these elusive creatures is important to the conservation of habitats for migratory stopover and overwintering and is of such a scale that it requires a nationally cooperative effort. The project has both a purely scientific as well as an educational aspect. The Northern Saw-whet Owl banding stations that I will be creating will be placed as near the campus of Louisiana State University-Alexandria as possible in order to allow the station to serve not only for research, but to stir student interest in wildlife biology.

Geolocators and waterthrush migration

The goal of this project was to elucidate the routes of migratory pathways and over-wintering sites of a Neotropical migrant, the Louisiana Waterthrush using color and federal banding and the placement of geolocators. Migratory birds are suffering widespread decline, and, though they are often well-studied on their breeding grounds, we know little of what becomes of them during their migrations, during migratory stopovers, and on wintering grounds in Central and South America. Though these birds may be protected in breeding areas in North America, this may not be the case on migratory stopover sites and wintering grounds. The destruction of habitat and increasing uncontrolled use of pesticides on wintering grounds are among many reasons considered suspect for the decline of migratory birds overall. Scientists for many years have used color and federal banding in hopes that birds will be recaptured along their migration routes and on breeding and wintering sites such that pieces of the puzzle individual migratory routes may be better understood such that the species might be better protected overall. However, these efforts, along with satellite tracking and stable isotope studies, have not been proven to be highly successful. Only recently have geolocators become light enough to be carried by migratory songbirds, opening a doorway for study and insight.birds,

Fifteen male Louisiana Waterthrushes on 4 streams in the watershed of the Upper Buffalo National River were banded with color bands and fitted with geolocators. Two birds were color-banded, but not fitted with a geolocator as a result of one being female and therefore likely having reduced site fidelity compared to the males and the second becoming stressed during the fitting procedure and thus being released to avoid any harm to the bird. Birds were monitored after having carried the geolocators and appeared to continue normal and healthy activities. Seven of 15 birds were recaptured the following year. All birds recaptured that were still wearing geolocators showed detrimental impacts of the geolocators through skin abrasions and bruising around the thighs as well as layers of epithelial tissue and feathers collector around the string of the geolocator harness. As a result, I highly suggest that teetering birds such as the Louisiana Waterthrush should be avoided as subjects for geolocator studies using the above method of outfitting the birds with harnesses and geolocators.

Observations of individual discrimination of humans by rural Northern Mockingbirds (Mimus polyglottos)

A study was conducted with an undergraduate research student to accomplish her required research project for a course in Ecology. Our objective was to determine if rural Northern Mockingbirds could recognize individuals by having different individuals create an indication of posing different levels of threat. Previous research at The University of Georgia found that the birds could recognize different student researchers and attributed this ability to the fact that the mockingbirds were urban. We were interested to see if mockingbirds that could be considered rural as opposed to urban would have the same abilities. Methods included having an individual approached a mockingbird nest once every day for four consecutive days, thus posing a greater threat to the nest, and recording the number of alarm calls, number of attacks, and the flush distances for each trial. Afterward, a different individual approached the nest on the final day. The first and fifth trials were compared first through fourth trials were compared to see if the mockingbird became increasingly defensive of the nest with the same intruder. There was no difference in responses of the birds to the intruders they encountered for the first time. However, the number of alarm calls and attacks showed a significant regression from the first through the fourth trial with the same individual posing an increasingly greater perceived risk of threat. This supported the hypothesis that rural Northern Mockingbirds were able to recognize individual humans similar to urban Northern Mockingbirds.

Assessment for contamination of streams and riparian habitat by toxins associated with non-traditional gas extraction techniques: bioaccumulation among trophic levels in aquatic, terrestrial, and at the aquatic-terrestrial interface of watershed streams

The goal of this project was to determine if contaminants such as barium and strontium associated with hydraulic fracturing of shale layers through ‘fracking’ compounds and resulting flowback or produced water are entering surface and groundwater, settling in sediment and microbes, including benthic algae, being assimilated by benthic macroinvertebrates, and then being bioaccumulated within populations of Louisiana Waterthrushes, which depend upon macroinvertebrates as their primary food source. My role in this study is at the trophic level where we wished to determine if contaminant bioaccumulation was occurring in breeding Louisiana Waterthrushes and their offspring. Waterthrushes maintain linear breeding territories along headwater streams and have high site fidelity across years. They have a single molt that occurs on the breeding territory previous to fall migration. Contaminants, if present, are sequestered within the growing feathers. Once a feather finishes growth, its blood supply atrophies, and feathers become an archive of toxins within the bird’s body at the time of molt. Thus, we have access to a reliable historical record of bioaccumulation of contaminant concentrations that can be collected at any time in the year between one molt and the next. The same physiological sequestration of toxins occurs in nestling feather development. Comparisons were made between streams with different densities of gas wells within their catchments and streams without wells. Our findings were complemented by those of a similarly designed study in the Marcellus Shale. This allowed more powerful regional comparisons to be made of geological differences. We worked in concert with the Dartmouth Toxic Metals Superfund Research Program, New Hampshire, to assure a high quality of analysis of feather samples. We found that waterthrushes in both the Marcellus and Fayetteville Shale regions, on territories within catchments associated with hydraulic fracturing, had accumulated contaminants associated with ‘fracking’ in the form of barium and strontium. We also found significantly higher levels of these metals when comparing current samples with those collected from historical samples taken from the same catchments previous to the beginning of fracking operations.

Completed: Doctoral Research, Spring 2012

To integrate the study of behavior with ecology, biodiversity, and community and ecosystem dynamics, my doctoral research was dedicated to understanding the behavior of territoriality in both its behavioral and ecological frameworks. Territoriality can be defined in light of behavior as the action of defense of an area to exclude others, or it can be defined ecologically as the outcome of the behavior of defense in which an area is exclusively occupied. The first definition is useful to those interested in how territories are established and maintained. The second is useful to those interested in the allocation of resources among individuals and how of resources in a changing environment can, in turn, change the dynamics of the territory itself.allocation

The above two studies were dedicated to establishment and defense of territories via individually unique songs of the Louisiana Waterthrush, and to determine if birds had the ability to recognize neighbors, strangers, and neighbors at incorrect boundaries. A suite of 23 territorial males was color-banded and followed over a period of four years. Males showed high levels of site fidelity to territories. Their abilities for discrimination of neighbors and strangers were tested using playback and recordings of behavioral and vocal responses. Behavioral responses were analyzed using ethograms. Songs were analyzed using current techniques in bioacoustics. Significant differences were found in the birds’ responses to different categories of individuals, suggesting their ability to discriminate.understanding the

Ph.D. Dissertation: Ch. 4 Leaf-pulling by Louisiana Waterthrushes: prey availability due to a unique foraging maneuver in a stream environment

The Louisiana Waterthrush is a riverine specialist and an obligate riparian species in that it relies almost entirely upon aquatic invertebrates as prey. My objective for this study was to simulate the birds’ foraging maneuver in light of optimal foraging theory and to determine if density, biomass, and assemblage of prey differed among configurations of leaves within the stream environment and if these variables were affected by the degree of anthropogenic change occurring in territories on different streams. I concluded that an optimally foraging Louisiana Waterthrush would be more successful pulling leaves from centers of shallow riffles in healthy stream reaches within constraints of nutrient availability of prey and the potential of its own predation. In addition, I found that differences in biomass, density, and distribution of taxa occurred among territories with different degrees of nutrient and sediment input such that in more polluted reaches success of foraging may correlate foraging choices with the ubiquitous nature of pollution-tolerant taxa and facultative taxa seeking refuge across multiple areas of the stream environment.

Ph.D. Dissertation: Ch. 5 Louisiana Waterthrushes, (Parkesia motacilla), of the Buffalo National River watershed and their relationship to a changing riparian habitat

This study was devoted to the conservation of the Louisiana Waterthrush and the watershed of the Buffalo National River. Eighty-nine percent of the river’s watershed lacks federal and state protection status. Much of the watershed is being harvested for timber and cleared and used for cattle pasture and chicken farming. These practices, along with increased road and urban development, are resulting in increased pollution, increased run-off rates with more sediment entering the river, and floods peaking at higher levels. I used habitat assessment and bioassessment metrics indicative of organic pollution and comparisons of pollution-tolerant and intolerant taxa to determine significant functional relationships between these variables and the lengths of waterthrush territories with longer territories found in more polluted reaches. My results suggest that Louisiana Waterthrushes could be incorporated into bioassessment metrics as indicators of stream ecological integrity in the watershed of the Buffalo National River.

Behavior and chip note vocalizations of female hooded warblers, Wilsonia Citrina, during nest defense

The objective of my master’s research was to determine if vocalizations and behavior differ with respect to experience of females, types of predators and timing of nesting cycles. In the presence of a predator, black rat snake or grey squirrel, experienced females moved onto nests silently, and inexperienced females usually moved onto the nest while vocalizing. Experienced females also varied their vocalizations in the presence of a more dangerous predator, while inexperienced females were more likely to vocalize in the same manner regardless of the degree of threat posed by the predator. Lengths of intervals between vocalizations decreased as nest cycle progressed and, therefore, with parental investment. Results indicated behaviors and vocalizations of females change in subsequent nesting seasons and that they learn to differentiate between predators and events with experience.
