RUBL did not perch on middle island - they flew to 3rd island and to 4th island the. The RUBL came in on a different trajectory (11° - almost due North) than previously observed. We observed that RUBL vocalizations had two distinct patterns tonight. Upon arrival RUBL would perch in trees on the 2nd island and sing a “kerglee” song. However, after most RUBL had come in, the vocalization changed to a “squiggle” type call; just before the flock began to fly from Islands 2 & 3 towards the final roosting area. RUBL went to roost (7:02 pm) at the same location in the marsh by the Rail Trail as reported in previous checklists. Photo courtesy of Brad Smith. Both sound recordings were captured by Gino Ellison.
