A bird stands on a dc electric line.?

A bird stands on a dc electric transmission line carrying 2460 A (Fig. 18-34). The line has 2.8 multiplied by 10-5 resistance per meter and the bird's feet are 4.0 cm apart. What is the potential difference between the bird's feet? I got an answer of 0.00246 V and it is not correct. Please help.
