Détails de l'observation
Group of black headed gulls flying over the pond. First alerted to their presence by their calls, which sounded much more like Franklin’s than Bonaparte’s. The birds appeared larger than Bonaparte’s as well, though hard to tell from a distance. Photos, though mediocre, show no white leading edge of primaries and a clear white trailing edge of the wing. I also managed to get a very poor quality audio recording.
