NOTE: This cache was placed for the NoVAGO Spring Fling - Redux Event GC1BHNG. The coordinates listed on the cache page are "bogus". In order to find this mystery cache you will first have to complete the cache named “Rock n Robin” GC1BNXF, the actual cache coordinates for this cache are listed at the top of the log in the final stage of “Rock n Robin".
A cache placed in Algonkian Regional Park, Loudoun County, Virginia. The park is managed by the Northern Virginia Regional Park Authority (NVRPA). Park hours are dawn to dusk, do NOT hunt this cache at night. You may have noticed that something was “missing” at the final stage of Rock n Robin (the Robin's nest was missing!!!), well this is it!!
Nesting habitat: Diversified: residential gardens, woodlands, urban parks, etc.
Robins were forest-nesting species but have, over time, become especially adapted to cities and open areas. They now commonly nest in gardens and parks although they can be found in just about any type of habitat, apart from swamps and marshes.
Nest support: Diversified: trees, bushes, vines, stumps, buildings (e.g., roof gutters), fences, open nest boxes, etc.
In trees, the nest is often found in a fork or on a strong branch. Robins nest early, sometimes before leaves are out. For this reason, the first clutch is often put in coniferous trees (e.g., spruce, cedar; well-hidden from predators) while the second one will often be in deciduous trees (e.g., maple, hawthorn). Interestingly, Robins can also establish their nest in open nest boxes (boxes without one of the panels) anchored to a tree or a building.
Nest description:
Variable material used: twigs, dry grass, mud, scraps of cloth, etc.
Only females build the cup-shaped nest; up to six days may be required. Twigs and grasses are placed in a cup-shape and are held together by mud. Strings, scraps of cloth and pieces of paper are also often used. The inside of the nest is covered with fresh grass.
Side note: If you continue past Robin’s Nest (there is a paved path close by) you’ll come upon the trailhead for the newly designated Algonkian Regional Park Sanctuary Trail. From that trailhead on....access is limited to the path only, NO off-trail excursions!! Although it looks like a great area to place caches...the wording on the sign at the trailhead would indicate otherwise. Explore the area, but please follow the guidelines/instructions listed on the sign. See photo of sign at the Sanctuary Trail trailhead.

NOTICE: Please be respectful of the posted park hours. If you enter the park after hours you are trespassing. If you are stopped you can be ticketed or arrested and will put the future of geocaching in the parks in jeopardy.
