The charge character of Andreev bound states (ABSs) in a three-terminal semiconductor-superconductor hybrid nanowire was measured using local and nonlocal tunneling spectroscopy. The device is fabricated using an epitaxial InAs/Al two-dimensional heterostructure with several gate-defined side probes. ABSs give rise to distinct local and nonlocal conductance signatures which evolve as a function of magnetic field and gate voltage. At high magnetic fields, ABSs are found to oscillate around zero as a function of gate voltage, with modifications of their charge consistent with expectations for the total Bardeen-Cooper-Schrieffer charge of ABSs.
