The Bajamar Star is an early O star that ionizes the North America/PelicanNebulae. In projection, it is near the geometric center of the H II region, butappears to lie outside any of the main stellar subgroups. Furthermore, in GaiaDR2, there were slight discrepancies between this star and the rest of thesystem in parallax (2$\sigma$ larger) and relative tangential velocity (~6km/s). Using Gaia EDR3, we find that the parallax discrepancy has disappeared,but the velocity difference remains. These results are consistent with the starhaving escaped from a subgroup.
