To find the height of the oak tree, we can use the Pythagorean theorem. The situation can be described as a right triangle where:

- One leg of the triangle (the distance from the base of the tree to the bird) is 24 feet.
- The hypotenuse (the distance the bird flew to reach the top of the tree) is 30 feet.
- The other leg, which we need to find, represents the height of the tree.

According to the Pythagorean theorem:

\[
a^2 + b^2 = c^2
\]

where \(a\) and \(b\) are the legs of the triangle, and \(c\) is the hypotenuse.

In our case:
- \(a = 24\) feet (distance from the base of the tree)
- \(c = 30\) feet (the distance the bird flew)

Let \(b\) be the height of the tree. The equation becomes:

\[
24^2 + b^2 = 30^2
\]

Calculating the squares:

\[
576 + b^2 = 900
\]

Now, isolate \(b^2\):

\[
b^2 = 900 - 576
\]
\[
b^2 = 324
\]

Next, take the square root of both sides to find \(b\):

\[
b = \sqrt{324} = 18
\]

Thus, the height of the tree is \( \boxed{18} \) feet.
