פרטי השורה
At least 3 out of 4 responded with typical grunt calls to PB and these were on the inland side of the tributary to Marsh Creek. One of the 3 was observed as it came out to look at us (or the rail making the calls!), and also responded to my vocalization using the "3-stoogies Curly" call. The fourth was on the river side close to where phragmites started and only responded with repeated "ki-dek"s for several minutes (heard as we departed and later when were in Marsh Creek half way to Little Marsh Creek). The VIRA habitat here was different from the typical Choptank R marsh habitats we encountered today. It consisted of low to middle sized bushes (1-3 feet) with a broad-leaf grass type (12-24 inches) interspersed throughout. The bushes made up about 40% of the habitat area. There were irregular openings and spacings between the plants (which had root clumps; the tide was starting to fall) that the rail we observed would walk through. The size of the habitat was limited, probably no more than 2 acres and closer to 1 acre. In contrast, mainly tall (3 to 7 feet) phragmites dominated the balance of this marsh and the MAWR and Red-winged BBs used these phragmites areas - we did not observe wrens or blackbirds in the VIRA habitat. Interestingly, towards drier land where the bushes got bigger and where trees began, sang the Song Sparrow.
