    Description of Habitat

    Rocky Ridge located in Westminster, VT has a north - south alignment and is situated due west of Interstate 91. Ridge elevation is approximately 1,100 ft msl. Vegetation is predominantly forest.

    Behaviors Observed

    Observers were located at Boggy Meadows Farm off River Road South in Walpole, NH. Bird was first sighted flying south along ridgeline. Maximum observation distance even with aid of scope presented an identification challenge. Enough detail was seen (large all black bird with wings held at a slight dihedral) leading to an initial identification of Turkey Vulture; however, bouts of soaring were interrupted by brief series of quick, shallow (choppy) wing flaps. It became apparent that the bird was drifting toward us and with continued observation our initial identification was doubted and a Black Vulture became more likely.

    Description of Vocalizations

    None.

    Verbal Narrative & Description of Observation

    As distance between observers and bird closed visual details came into view. Eventually the bird flew within close range and photos (attached) were taken.

    Relative Size & Shape

    Larger than Common Raven.

    Head

    Bird short necked with naked, all dark head.

    Feet & Bill

    Not noted.

    Upper Back

    Not clearly visible from observers' vantage point..

    Lower Back & Rump

    Not clearly visible from observers' vantage point.

    Wings

    Wings were broad but not as elongated as those of Turkey Vulture. Outer primary feathers formed obvious "fingers" which were more or less of uniform length giving wings a squared-off (blunted) appearance. Wings were black except for decidedly white outer primaries.

    Breast, Belly, Flanks, Under Tail Coverts

    All black.

    Tail

    Tail broad and short; no markings.

    IMPORTANT: What similar species were eliminated when making the identification and how was this bird different?

    Flight behavior, overall body shape, and white outer primaries eliminated Turkey Vulture.

    Other Notes & Comments

    Observation was made while conducting the Saxtons River CBC. Even though the observers were in NH , the bird when first spotted and for several minutes before flying crossing the Connecticut River (state line) was in VT. Sighting was initially submitted to eBird. Report is generated from that filing, analysis of photos taken, and memory. Photos include the two originals and respective blow ups.
