* This bird had been flying for a considerable time, hence the high temperature. For 
this reason, in calculating the mean temperature of the cormorant, this figure is excluded. 
+ On November 23, a pair (male and female) of velvet scoter ducks (CEdemia fusca) were 
shot, but the notes of the body temperature have been lost.
