List of the Birds of the Vicinity of the Guest House 
In the following list, common birds which have been described 
rather fully in the preceding chapter will be mentioned only 
briefly, to avoid repetition; and only such comments will be given 
here as will more fully describe species mentioned briefly in the 
preceding list. It is intended that these two chapters shall consti- 
tute an introduction to the summer birds of the Palisades Interstate 
Park. 
1. Bluebied. Sicilia sialis sialis (Linn.) 
The Bluebird is apparently not common in the Park. My first 
notice of it was at Blauvelt, June 21, beyond the limits of the 
region described in this report, where a family was observed work- 
ing around the building of the military training grounds, and occa- 
sionally their subdued warbles were heard. On July 31 an adult 
Bluebird and two others were seen at Kanahwauke Lake, on the 
telephone wire. One of the juveniles uttered a short warble in a 
quiet, plaintive tone. On August 1 I found Bluebirds frequenting 
an old pasture hillside near Jolmsontown, outside of the Park 
property. 
2. Robin. Planesticus migratorius migratorius (Linn.) 
The Robin is common everywhere in the Guest House neighbor- 
hood. At the camps on the various ponds and lakes it nests in 
familiar places, often on beams of porches, corners of cabins regu- 
larly in use, or any site it fancies along trails, roads, or near out- 
buildings. On June 13 I found a Robin’s nest in the edge of the 
woods near the Guest House garage. It was made in a hollow of 
the fork of a dead chestnut tree, about four feet from the ground.
