Intraspecific Competition of Little Heron

Competition is unavoidable when the population growth at high densities. At higher densities, resources will become limited as such the effect of intraspecific competition will happen. Intraspecific Competition refer to competition for resources within the same species.

I am fortunate enough to witness the intraspecific competition between 2 Little Heron (Butorides striatus) while I was on a birding trip at North Sulawesi.

This Little Heron happily landed near a coastal area thinking to feed while the tide is low.

Almost immediately, the other Little Heron that already started feeding earlier at the same location move in to protest to the 'intruder'.

A fierce fighting is looks set to happen...
After few rounds of chasing, eviction, display of muscle,...
The 'intruder' decided to back off.

The incumbent Little Heron managed to defense her territory and the 'intruder' just flew off to other location.
