- If the sex cycle is broken by loss
of nest or eggs the new cycle will
restart with the minimum or no amorous
courtship. A [male symbol] may regularly copulate one
female + regularly court another.
In #2. Courtship is self stimulatory
The more actively a bird courts the sooner
the various sequences of love phases are
passed through even with a sluggish
partner. Mutual defence of a nest territory,
mutual nest building + the existence of
close contact with a nest raiding fight all
act as stimulation to shortening the
period between advertising + marriage. Thus
it is total energy expended toward or
together with the partner that is important.
3. From 5-6 weeks young cormorants
develop a lot of sexual behaviour that
is spontaneous + not directed - the vacuum
phase - These gradually become a form
of greeting between siblings - the bond
expressing phase.
Siblings who roost together continue
this greeting + spend more + more time at
home together. Those that are alone or
lose their siblings cease coming home
very early in their growth.
Close contact with amorous greeting
is essential. Sibling birds that roost 6 ft [feet]
apart do not form or maintain pairs.
A separation of 6 days results in
failure to recognize a former
sibling associate.
_______
A very interesting display of
living + dead foraminifera by
[space left blank] of U. [university] of Col. [Colorado] Dept [Department] of
Palaeontology. Moving discs that
pass slowly under the microscope is an
excellent idea. The protoplasmic streaming
of the pseudopods of living Algromia
laticollaris [underlined] was most obvious +
interesting as also were the
magnificent micro x ray photos of
the internal structure of shells. There
were some beautiful demonstrations of
mitosis + meiosis with figures
beautifully clear.
