Upon arriving at the Bashakill this morning it was immediately evident that there had been a turnover of birds last night. In fact, it was the most significant night of migration we’ve experienced this spring. I entered the parking area at the Pine Boat Launch, finding a female FOS RED-BREASTED MERGANSER feeding just off shore. There were many of the regular ducks present. As I walked out to the tower, I spotted two Hermit Thrush feeding in the pines. I had hoped for a Pine Warbler, but had no luck. Upon my return to the launch, I couldn’t find the merganser. I had notified a number of friends of the birds presence so I continued to look for it. I went out the Stop Sign Trail, where I had another FOS, RING-NECKED PHEASANT. From there I went to Haven Road. Here there were many ducks that we’ve been seeing regularly. From there, I headed to the Main Boat Launch and the Birch Trail. Once on the Birch Trail, I heard my second new species at the Bash, a YELLOW-BELLIED SAPSUCKER drumming in a dead tree. Its Morse code style of tapping easily recognized. Out on the trail I found many Eastern Phoebes, which were abundant everywhere today. Once I was done there, I headed to the Deli Fields to try again for PINE WARBLER. I found perhaps as many as three of these birds! I then decided to head back to Haven Road, the hottest spot on the kill, to see if anything new had come in there. I found a flock of sparrows that included two FOS species. A gorgeous VESPER SPARROW and two SAVANNAH SPARROWS! I let many of my birding friends know about the birds and by afternoons end, eleven people had seen the sparrows on Haven Road!
