The following weekend I headed out to the west end. My goal was the Morris Island Conservation Area, but I decided to stop in at the Bill Mason Center first while I waited for it to warm up. Although the morning was sunny, it was cool enough to need a jacket. Few birds were singing as I entered the marsh. I heard no Swamp Sparrows, Common Yellowthroats, or Yellow Warblers, although I saw two Yellow Warblers on my walk. I also saw a Rose-breasted Grosbeak and a couple of robins in the marsh, but no rails or grackles or Red-winged Blackbirds. The blackbirds have left their nesting territories and can be found in large flocks in cornfields and other agricultural areas, returning to roost in nearby wetlands at night.
