The volume of Snowy Plover Charadrius alexandrinus alexandrinus eggs w
as measured using an egg volumeter. The volumeter was tested both indo
ors and outdoors using steel balls and real eggs, respectively. Both m
easurements showed that the volumeter is accurate. The volume of Snowy
Plover eggs was 8.4 +/- 0.4 cm(3). It is suggested that a simple devi
ce be used to measure volume because the error of the volumeter is sma
ll (0.06 cm(3)) and the device is easy to use in the field.
