[All photographs copyright, Gary Nunn 2014] – This Yellow-throated Warbler Setophaga dominica was first found by Ed Ervin on 09 June 2014 in the University City neighborhood of San Diego. Luckily the bird stuck around and news came out that it was still present on 18 June 2014. I drove over to the location on Genesee Avenue, between Nobel Drive and Decoro Street, and sure enough it could be heard singing from the Torrey Pines outside the apartment complex. I quickly tracked it down singing intermittently from both the pine and other ornamental tree tops in the area. It was remarkably aggressive and sometimes kept busy attacking its own reflection in apartment windows! This bird appears to show characters of the western type albilora with the white supraloral stripe and extensive black coloration of the fore crown.
