There are only Yellow Warblers on this side of the orchard, so we move on to the sidewalk below the White Pines. The beauty of the apple blossoms is enhanced by their contrast with the gnarled limbs of these old and dying trees. As we emerge into the wet meadow we're met with the chatter of a House Wren and from the orchard beyond an Eastern Bluebird calls. We're lucky today: a Tufted Titmouse and a Pine Siskin are among the birds at the trays. But before we squeeze through a broken place we check at the top of the rise to our right the backyard feeders of several houses. Following the fence we soon come to the open meadow and abandoned orchard to our left. A Brown Thrasher sings ahead along the forest margin.

Since then monitoring was expanded to include grasslands in other parks including Antietam National Battlefield (ANTI) (89 plots), Harpers Ferry National Historical Park (HAFE) (26 plots) and Monocacy National Battlefield (MONO) (68 plots). The protocol was applied at these points and worked well. During the 2014 field season 44 grassland monitoring plots were established at Manassas National Battlefield Park. In 2014 the protocol was tested to see if it could be applied for monitoring grassland birds. In addition, temperature, humidity, and weather conditions were also recorded. Species detections were recorded at each location as well as whether the bird was observed within 50m or between 50 & 100m from the observer.
Each site was visited twice per year by alternate trained observers. Point counts were conducted at roughly 384 forest locations annually across 11 National Parks during the breeding seasons from 2007 - 2016. Data were collected following the protocol outlined by Dawson and Efford (2006). These data represent the first ten years of data collection (2007-2016) on avian abundance/density and distribution in the National Capital Region as part of the Inventory and Monitoring Program.
