Gabrielle saw a total of 5 + 4 + 3 = 12 birds.
Chase saw a total of 2 + 3 + 5 = 10 birds.
The difference between the number of birds Gabrielle and Chase saw is 12 - 10 = 2 birds.
To find the percentage difference, we need to divide the difference by the number of birds Chase saw and multiply by 100.
So, the percentage difference is 2/10 * 100 = 20%
Therefore, Gabrielle saw 20% more birds than Chase.
#### 20
The answer is: 20
