Red-footed Booby ; (l Oct) Found an adult bird brooding a Great Frigatebird nestling- 
Caught four pairz of adults. In each case one bird was slightly smaller especially 
the diameter of the neck. These birds also had green on the bill and a higher pitched 
voice. The difference in the voice was clear. Jeff caught two birds and I was able to 
tell that they were a pair even though ik® my head was down.

sex this species at least 50^ of the time and with practive even as well as Blue¬

acting very much like a bird with its young.
