About 25 people attended the weekly walk at Dyke Marsh, sponsored by the Friends of Dyke Marsh. We walk is open to all, and meets in the Belle Haven picnic area at 8am. We were fortunate today in having a bevy of trip leaders in attendance, including Rich Rieger, Larry Meade, Ed Eder, and Sherm Suter. That plus some other sharp-eyed attendees resulted in a list of 69 species, without the benefit of many migrants. We had pretty good success viewing water birds from the picnic area, including a large flock of blue-winged teal which contained an early green-winged teal, shorebirds on the distant mudflats, several pied-billed grebes, a large flock of Caspian terns on the mudflats, and large numbers or great blue herons and great egrets. We also saw a distant peregrine falcon perched on the Wilson bridge. From the marina we saw a black tern in close to breeding plumage flying over the hydrilla mat. Also viewed around the marina were green heron, yellow and Nashville warblers and an American redstart. The wildlife trail was rather quiet, although we did see black-and-white warbler, Baltimore oriole, red-eyed vireo, and great-crested flycatcher. From the end of the boardwalk we saw a spotted sandpiper, and on the way back we heard a blue grosbeak. A complete list is below.
