Margaret C. MacCluskie Paul L. Flint 1995 <p><span>Previous studies of waterfowl have measured nest attendance and nest temperature separately using a variety of methods. A device was developed that monitors nest attendance and temperature simultaneously. The device consists of an artificial egg with a microswitch that records nest attendance and a thermistor probe that records temperature. Data are stored in a single-channel data logger. The device described measures the length of incubation breaks, and nest cooling and warming rates.</span></p> application/pdf en Wiley A device for simultaneously measuring nest attendance and nest temperature in waterfowl article
