Disturbance Caused by Aerial Waterfowl Surveys During the Nonbreeding Season

Andrew D. Gilbert, Christopher N. Jacques, Joseph D. Lancaster, Aaron P. Yetter, more

The Journal of Wildlife Management > 84 > 6 > 1063 - 1071

Aerial surveys flown at low altitudes allow detection, identification, and enumeration of waterfowl and other waterbirds, but few studies have assessed disturbance to these guilds during the nonbreeding period. Excessive disturbance can potentially increase energy expenditure and exposure to hunting mortality contrary to objectives of many waterfowl sanctuaries where surveys are conducted. We used...

Variation in True Metabolizable Energy Among Aquatic Vegetation and Ducks

Margaret C. Gross, Sarah E. McClain, Joseph D. Lancaster, Christopher N. Jacques, more

The Journal of Wildlife Management > 84 > 4 > 749 - 758

Avian diet quality is typically measured using true metabolizable energy (TME_N), which is a measure of assimilable energy of food items accounting for innate endogenous losses. Originally developed for use in the poultry industry, TME_N methods have been adapted to determine the value of natural foods consumed by waterfowl to parameterize bioenergetics models for conservation planning. Because there...

Energetic implications of floodplain wetland restoration strategies for waterfowl

Sarah E. McClain, Heath M. Hagy, Christopher S. Hine, Aaron P. Yetter, more

Restoration Ecology > 27 > 1 > 168 - 177

Modifications of the Illinois River and associated tributaries have resulted in altered hydrologic cycles and persistent river‐floodplain connections during the growing season that frequently impede the establishment of hydrophytic vegetation and have reduced value for migratory waterfowl and other waterbirds. To help guide floodplain restoration, we compared energetic carrying capacity for waterfowl...

Associations of intestinal helminth infections with health parameters of spring-migrating female lesser scaup (Aythya affinis) in the upper Midwest, USA

J. Conner England, Jeffrey M. Levengood, Josh M. Osborn, Aaron P. Yetter, more

Parasitology Research > 2018 > 117 > 6 > 1877-1890

Thousands of lesser scaup (Aythya affinis) die during spring and fall migrations through the upper Midwest, USA, from infections with Cyathocotyle bushiensis and Sphaeridiotrema spp. (Class: Trematoda) after ingesting infected intermediate hosts, such as non-native faucet snails (Bithynia tentaculata). The lesser scaup is a species of conservation concern and is highly susceptible to these infections...

Mallard survival, movements, and habitat use during autumn in Illinois

Aaron P. Yetter, Heath M. Hagy, Michelle M. Horath, Joseph D. Lancaster, more

The Journal of Wildlife Management > 82 > 1 > 182 - 191

The Illinois River Valley (IRV) in central Illinois, USA, provides migratory stopover habitat for millions of waterfowl during autumn and spring in the Mississippi Flyway. Mallards (Anas platyrhynchos) are the most abundant species of waterfowl during autumn migration and the most harvested duck in Illinois. We investigated mallard migration ecology in central Illinois, USA, to address information...

Opportunity costs influence food selection and giving‐up density of dabbling ducks

Heath M. Hagy, Joshua D. Stafford, Randolph V. Smith, Aaron P. Yetter, more

Journal of Avian Biology > 48 > 6 > 804 - 814

The interaction of animals with their food can yield insights into habitat characteristics, such as perceived predation risk and relative quality. We deployed experimental foraging patches in wetlands used by migrating dabbling ducks Anas spp. in the central Illinois River Valley to estimate variation in seed removal and giving‐up density (GUD; i.e. density of food remaining in patches following abandonment)...

Evaluating a Rapid Aerial Survey for Floating-Leaved Aquatic Vegetation

Jay A. VonBank, Andrew F. Casper, Aaron P. Yetter, Heath M. Hagy

Wetlands > 2017 > 37 > 4 > 753-762

Aerial surveys are a valuable tool for monitoring wildlife and their habitats throughout North America, but manned aerial surveys for monitoring aquatic vegetation communities have seldom been evaluated rigorously. We used a fixed-wing aircraft and modified double observer method to survey an invasive aquatic macrophyte, water hyacinth (Eichhornia crassipes), and other floating-leaved aquatic vegetation...

Waterbird response indicates floodplain wetland restoration

Heath M. Hagy, Christopher S. Hine, Michelle M. Horath, Aaron P. Yetter, more

Hydrobiologia > 2017 > 804 > 1 > 119-137

Despite extensive anthropogenic degradation of most wetlands and other aquatic habitats associated with large rivers in the Midwest, the region still supports continentally important numbers of waterbirds during autumn and spring migration; however, few data exist to evaluate wetland restoration success and identify thresholds where changes in management may be necessary to meet conservation targets...

Response of aquatic vegetation communities and other wetland cover types to floodplain restoration at Emiquon Preserve

Christopher S. Hine, Heath M. Hagy, Michelle M. Horath, Aaron P. Yetter, more

Hydrobiologia > 2017 > 804 > 1 > 59-71

More than half of the natural wetlands in the Illinois River valley (IRV) have been lost through conversion of floodplain wetlands and lakes to drainage and levee districts for agricultural production. During 2007–2013, we monitored the response of wetland vegetation communities to restoration at Emiquon Preserve, a former floodplain that was drained and farmed for more than 80 years. Spatial coverage...

Evaluating tradeoffs between sanctuary for migrating waterbirds and recreational opportunities in a restored wetland complex

Heath M. Hagy, Michelle M. Horath, Aaron P. Yetter, Christopher S. Hine, more

Hydrobiologia > 2017 > 804 > 1 > 103-118

Wetland restoration in highly modified landscapes involves balancing target ecosystem functions and values with constraints of landscape and stakeholder context. Often, a restored wetland complex cannot meet all target conditions simultaneously, and tradeoffs must be understood, evaluated, and quantified. We examined the tradeoff between providing migratory bird sanctuary and increasing public recreational...

Stopover duration of mallards during autumn in the Illinois River valley

Heath M. Hagy, Aaron P. Yetter, Kirk W. Stodola, Michelle M. Horath, more

The Journal of Wildlife Management > 78 > 4 > 747 - 752

Estimates of time spent at migratory stopovers are often used to develop habitat conservation objectives for a variety of avian species, namely waterfowl. Because of limited previous research and a need for accurate conservation planning objectives, we estimated stopover duration and factors influencing stay of mallards (Anas platyrhynchos) in Illinois using radio telemetry during autumns 2009 and...

Historical and Contemporary Characteristics and Waterfowl Use of Illinois River Valley Wetlands

Joshua D. Stafford, Michelle M. Horath, Aaron P. Yetter, Randolph V. Smith, more

Wetlands > 2010 > 30 > 3 > 565-576

Understanding changes in characteristics of floodplain wetlands over time could provide valuable information to guide management and restoration efforts. We compared characteristics of 29 Illinois River valley (IRV) wetlands mapped during two time periods between 1938–1959 and 15 wetlands re-mapped in 2005–2006. Average proportions of wetlands classified as bottomland forest, scrub-shrub, nonpersistent...
