A Sabines Gull was acting quite tame and feeding close to where we stood until this crow landed behind it (of all the places it could have landed....the crow was maybe 10+ feet behind it but was enough for the gull to take off, so that tells me gull and crow have had previous encounters). The Sabines Gull took flight soon as it did that. So, we were left to watch the crow and take a photo of it.
