Sunset at 7:28 pm. 52 F, wind SE 8. Parked on Heritage Lane and followed the Partridge Island Trail to the last island at Partridge. After 6:30 pm, I was at the back of the last island facing east with views of the rail bed and the east side of the middle island and Linda and Andy were on the opposite side of the last island with views of the first island. This was a multi-site survey night with Dave Williams and Constance Lapite observing from the rail bed. A large group of over 260 Rusty Blackbirds continues to stage to roost at Partridge Island, arriving tonight just after 7 pm and flying to roost on the east side of the rail bed after 7:25 pm (sunset at 7:28 pm). The Rusty Blackbirds staging to roost at Partridge Island represent only a portion of the total number of Rusty Blackbirds roosting in the marsh.

    Comments: The first three RUBL arrived on the first island at Partridge at 6:28 pm. Unfortunately we were also on the first island at Partridge and even though we retreated back to the last island they only stayed and sang for a few minutes before flying toward the rail bed. Rusty Blackbird numbers began to build on the back of the middle island at Partridge after 7 pm and were counted when they flew to roost between 7:25 pm and 7:36 pm. Close views through binoculars of 60 staging on the closest trees to me showed greater than 95% RUBL.

  23. Number observed: 30

    Comments: Common Grackles fly to roost earlier than Rusty Blackbirds. Between 7:15 pm and 7:23 pm, 20 Common Grackles left the trees at Partridge.
