September started with a bang today, when a Western Bonelli's Warbler was discovered in the plantation at 7:30 this morning. After showing sporadically for an hour, it conveniently flew into one of the mist nets, and was ringed at the observatory shortly after. This represents the rarest bird of the year so far, with only six previous records on the island.
The most notable small passerines seen included a Swift, seven Grey Wagtails, two Tree Pipits and a Reed Warbler. The Wryneck was also present.
