About 11:45 am, I was at my desk when I saw a Pine Warbler on the Bubbler rock via the Bubbler cam! This was the first time for this species to investigate the water feature, making it Bubbler Bird #112 (+1 hybrid). I ran downstairs to confirm my sighting when it circled back and I was able to get one photo. It's another harbinger of spring after a very long winter. By afternoon, I was pretty sure there were at least 2 birds. I took a few more photos of one feeding in the pond cypress and then perching briefly on a tree trunk. Look in the gallery for the photos!
