As part of my MSc project, in which I am
look ing at factors that affect breed ing success
of African Penguins on Robben Island, I am
looking at the effects of habitat choice, nest
type and shad ing on breed ing success, as well
as assessing the impact that choice of habitat
has on micro-climates experienced by incu-
bating parents. As mass-abandonment of
clutches early in the season is common, I
want to establish whether this is due to
extreme heat stress experienced by all nest
deserters, or whether it is triggered by the
behaviour of neighbours in some instances.
My hypothesis is that, in many cases,
nest deser tion is in fact not directly related to
heat stress but rather indirectly so, as it is a
reaction to the departure of nearby birds who
