Monticello Park shared in the migration wave experienced today in the area. I sighted 12 species of warblers including single sightings of Cape May, Blackpoll, and Nashville. A Northern Waterthrush worked a section of the creek all morning oblivious to the birders who could easily see the fine streakings on its throat. There were at least three other waterthrushes there, one a singing Louisiana. Ovenbirds were making themselves readily seen as well as heard. It was also thrush day there--there were many Wood, Swainson's and Veeries, and at least one late Hermit. The showy migrants--Scarlet Tanager, Rose-breasted Grosbeak, Baltimore Oriole, and Indigo Bunting--put in multiple appearances as well. In the ubiquitous category were White-throated Sparrows, Yellow-rumps and Robins. All in all, close to 50 species were present and most remained active into the early afternoon. This park is unique both for the variety of passerines it produces and the exceptional, close looks it provides. I am grateful that last year's construction activity apparently has not altered the park's ability to attract migrants. My hat (i.e., birding cap) is off to those who worked so diligently to persuade local authorities to keep disturbance to the park to a minimum. Ralph Wall Great Falls, Va.
