The birds also ""balk" quietly to each other and rub beaks gently and 
preen each other. I believe that these are actions of an already mated 
pair. In addition the adult will "talk" to an egg or to the young, either 
while sitting beside it or before settling down on it, as if reasuring it 
that everything was all right. 
It is interesting to watch the young being fed. The adult regurgitates 
some partially digested food in liquid form, after the young has indicated 
its desire by pecking ana biting at the adult’s bill and running its little 
'bill up and down the great big one. The adult then opens the bill and lets 
the food run down the lower mandible and the chick sticks its head sideways 
into the parent’s bill and scoops up the food with its lower mandible. The 
chick frequently gets a certain amount of the oily food on its head in the 
process. The parent can be observed tc swallow, probably the excess, after 
_ the chick has fed. 
s previously mentioned. Bob and I tagged 5 seals today north of the 
small boat landing on the west s3de of the island between f700 and 1800. The 
data is as follows. Animals which appear to be under 100 pounds I shall 
call yearlings, those still in black pelage are juveniles, and all others are 
adults. It is easy to sex animals by poking them to make them roll over and 
then observing the genital openings. The female aparently has a common cloaca 
type opening for both the vagina and urethra, and the anus. The male has a 
conspicuous penile opening on the venter one to two feet away from the anus, 
#2 yearling - not sexed (only half the tag remained on the animal) 
#3 yearling - male
