Daily energy expenditures of free-ranging Common Loon (Gavia immer) chicks Daily energy expenditures of free-ranging Common Loon (Gavia immer) chicks
We measured the daily energy expenditure of free-living Common Loon (Gavia immer) chicks using doubly labeled water (DLW). Average body mass of chicks during the DLW measures were 425, 1,052, and 1,963 g for 10 day-old (n = 5), 21 day-old (n = 6), and 35 day-old (n = 6) chicks, respectively, and their mean daily energy expenditures (DEE) were 686 kJ day−1, 768 kJ day−1, and 1,935 kJ day...

The oral bioavailability and toxicokinetics of methylmercury in common loon (Gavia immer) chicks The oral bioavailability and toxicokinetics of methylmercury in common loon (Gavia immer) chicks
We compared the toxicokinetics of methylmercury in captive common loon chicks during two time intervals to assess the impact of feather growth on the kinetics of mercury. We also determined the oral bioavailability of methylmercury during these trials to test for age-related changes. The blood concentration-time curves for individuals dosed during feather development (initiated 35 days...

Integrating SAS and GIS software to improve habitat-use estimates from radiotelemetry data Integrating SAS and GIS software to improve habitat-use estimates from radiotelemetry data
Radiotelemetry has been used commonly to remotely determine habitat use by a variety of wildlife species. However, habitat misclassification can occur because the true location of a radiomarked animal can only be estimated. Analytical methods that provide improved estimates of habitat use from radiotelemetry location data using a subsampling approach have been proposed previously. We...

Design and performance of a rugged standard operative temperature thermometer for avian studies Design and performance of a rugged standard operative temperature thermometer for avian studies
The lack of a truly satisfactory sensor which can characterize the thermal environment at the spatial scale experienced by small endotherms has hindered study of their thermoregulatory behavior. We describe a general design for a rugged, easily constructed sensor to measure standard operative temperature, Tes. We present specific designs for adult dark-eyed juncos (Junco hyemalis) and...

Statistical and procedural issues in the use of heated taxidermic mounts Statistical and procedural issues in the use of heated taxidermic mounts
Studies using mounts have an inherently nested error structure; calibration and standardization should use the appropriate procedures and statistics. One example is that individual mount differences are nested within morphological factors related to species, age, or gender; without replication, mount differences may be confused with differences due to morphology. Also, the sensitivity of...

Metabolic response to air temperature and wind in day-old mallards and a standard operative temperature scale Metabolic response to air temperature and wind in day-old mallards and a standard operative temperature scale
Most duckling mortality occurs during the week following hatching and is often associated with cold, windy, wet weather and scattering of the brood. We estimated the thermoregulatory demands imposed by cold, windy weather on isolated 1‐d‐old mallard (Anas platyrhynchos) ducklings resting in cover. We measured O2 consumption and evaporative water loss at air temperatures from 5° to 25°C...
