Coin flipping

I have flipped a coin 1000 times and written down the results (heads or
tails for each flip). Now, I'm being told that at one point, and for an
unknown number of flips, the coin was switched from an unbiased to a
biased one (let's say resulting in 67% tails instead of 50%). For
example, maybe flips 725 to 780 were with the biased coin, and all
other with the unbiased. Since I don't know this, I wish to find which
range is the most probable to be biased given the list of flips. How
can I do this?
