The Weaver birds from the African savanna exhibit a trade-off between risking starvation and being hunted by predators. As a result the birds that are of medium weight have the selective advantage and make up the majority of the population.

Which type of natural selection is at work here?

stabilizing selection

Stabilizing selection.

It favors intermediate phenotypes (medium weight) and selects against both extremes (too light → starvation; too heavy → predation), reducing variation around the mean.
