We give the asymptotic distribution of the zeros of Jacobi-Pi\~neiro
polynomials and multiple Laguerre polynomials of the first kind. We use the
nearest neighbor recurrence relations for these polynomials and a recent result
on the ratio asymptotics of multiple orthogonal polynomials. We show how these
asymptotic zero distributions are related to the Fuss-Catalan distribution.Comment: 19 pages, 2 figures. Some minor corrections and four new references
