Based on the ideal free distribution theory, you may predict that

A) the birds that are able to secure a territory on the preferred habitat have the highest reproductive success.
B) this shorebird exhibits sex-biased dispersal; while one sex remains on the preferred habitat, the other sex disperses amongst the other areas in order to reduce inbreeding.
C) the most preferred habitat also has the highest amount of intraspecific competition.
D) birds already established on the preferred habitat are in better condition and thus able to maintain their territories from any intruders.
