On 12 November 2018, while on a routine evening bird survey of the island, the SEFI crew encountered a third-cycle Lesser Black-backed Gull. This was a first island record for the species and one of only a handful that show up in California every year. Interestingly, we noticed that this bird was missing its left toes, a unique trait that makes it possible to track sightings of this individual in other locations. Sure enough, when the word was put out to the local birding community we discovered that the same bird had been spotted in Foster City, California last April!
