We investigate iterated applications of a dynamic known as birational rowmotion on rectangular posets, i.e. the product of two chains. We obtain a combinatorial formula stated in terms of the weighted enumeration of non-intersecting lattice paths. This work began at the 2015 AIM (American Institute of Mathematics) Workshop on Dynamical Algebraic Combinatorics. We thank AIM for its hospitality.
