Gradualism is when a change takes place over time. Punctuated equilibrium is when nothing changes for a very long time, then suddenly something new appears, after which another long period of no change occurs.
The gradualism model of evolution states that change occurs gradually over time. On the other hand, the punctuated equilibrium model states that change occurs suddenly or rapidly.

A combination of both gradualism and punctuated equilibrium best explains the pace of evolutionary change
punctuated equilibrium
Gradualism proposes that evolution occurs through a slow and continuous process, with small changes accumulating over time. Punctuated equilibrium, on the other hand, suggests that evolution happens in rapid bursts of change separated by long periods of little to no change. Both theories address the concept of how species evolve over time, but they differ in the pace and patterns of these changes.

No, it happens in small leaps. This is called punctuated equilibrium. Gradualism is actually the answer to the question though punctuated equilibrium is also another tempo of evolutionary change.
When someone does not believe in intelligent creation, it can believe in anything. Gradualism and punctuated equilibrium are two ways in which the evolution of a species can occur. Those terms were created when no missing link were never found. In the 1800's scientists were looking for missing links believing there were missing waiting to be dug up. Then came the punctuated equilibrium term when no missing was found.
over several thousand years the birds descendants evolve webbed feet and begin to feed on fish. is this an example of gradualism or punctuated equilibrium?

Punctuated equilibrium is commonly contrasted against phyletic gradualism, the belief that evolution generally occurs uniformly and by the steady and gradual transformation of whole lineages (called anagenesis). In this view, evolution is seen as generally smooth and continuous.
