Subject: [MASSBIRD] Cuttyhunk Island - Unofficial CBC - Sedge Wren

My son Corvus Sylvia and I completed an unofficial CBC of the island today. Owling component yielded no owls. Weather quite variable from sunny to snow flurries.
Winds 12-30 kts.
Temps 20-40 F
54 species
Distance 11.3 miles. Measured on App. 10 hours

We covered almost all areas of the island over the period. All effort were made to avoid overlap and we feel confident that we were successful. Much of the berry crop is almost gone from the island. Eaten mainly by the large flock of Starlings that is still present. Good sea ducks around the island.

Rarest bird Sedge Wren. Late or species high counts for Chipping Sparrow, Brown Thrasher, Virginia Rail, Merlin, Gray Catbird, Song Sparrow, Black Scoter and Common Goldeneye.

Funniest find only 1 Dark-eyed Junco all by itself at the West end in an area I tend to find single odd species.

Winter Wren 1
Sedge Wren 1 Very Rare late date. Possible latest winter record for Massachusetts. Last record found is Jan 3. Positive ID seen by both observers three times at close ranges (5-10 feet). Unfortunately no photos. The bird only did short flights and quickly perched then dove into grass. Found in area within 300 yds of the my last sighing this Fall. Habitat same tall grass border to marshy area. Small pale bird with weak flight. Soft mottling over body. Longish tail. Exactly as seen on other bird seen and photographed on 11/2/2019. Bird was first flushed within 5 feet of me and I had eyeball view in fight with bright sun over my shoulder that confirmed ID. We were able to flush it two more times at close range so other observer could see it and confirm. No doubt.
