+1 on the hops adding to head retention. (I have read it in quite a few articles lately)
However, I suspect the Pale Ale is Dry Hopped, while the others are not. My guess is that there are more micro hop particles floating around than the other beers, giving nucleation sites for the foam to start. You could filter/fine more to reduce the head problem if this is the case, but it will also effect the flavor of the Pale Ale as some of those particles is what gives you the bright hop flavor.
I would try a different hose length and/or dialing the PSI down when serving as a start...
