Every day now, there are migratory birds in my yard. Bathing and drinking from little puddles in the boulders. Eating from all the seed heads. Picking in the gravel. Last Tuesday there were, white crown sparrows and warblers. Among them this one. If anyone out there can identify it, i will be happy to know. Thanks.
ps. Sept 15 2009. Thanks Mary. It is very possible an Orange-crowned Warbler!
