    Description of Habitat

    Birds located in dense underbrush. Moved around in a small around of about forty feet by ten feet. Older growth forest on opposite side of trail. No other birds in immediate vicinity. Could hear Eastern Wood-Pewee from forest, but it was some distance away.

    Behaviors Observed

    Juvenile bird seen begging and following adult male Hooded Warbler. Witnessed the adult feeding the juvenile nine times, although feeding also seemed to occur several times while vegetation blocked view. Adult male gleaning insects and delivering them to juvenile. No self-feeding behavior observed by juvenile.

    Description of Vocalizations

    Adult male gave near-constant "chip" notes. Loud and emphatic. At one point the juvenile came very close to me and the adult's vocalization changed to a much thinner, quieter chip note, which silenced the juvenile.
    Juvenile's vocalizations more rapid, less musical. Would increase in intensity as adult approached with food.

    Verbal Narrative & Description of Observation

    Adult male feeding juvenile. Watched juvenile for an hour. Olive back to crown, unmarked wings, yellow underparts from throat to undertail, white outer tail feathers, dark lores, large eye and bill. Watched male feed juvenile nine times. Juvenile was very vocal almost the whole time. Witnessed begging, with wings slightly outstretched and tail frequently flared. Tail-flicking noted in both adult and juvenile.

    Relative Size & Shape

    Mid-sized warbler. Stocky with longish, squared tail.

    Head

    Crown yellowish olive. Cheeks yellow. Eye large and dark. Throat yellow. Nape olive-yellow. Dark lores.

    Feet & Bill

    Short, stocky looking legs. Pink feet. Bill large for warbler. Lower mandible lighter than top.

    Upper Back

    Olive. Unstreaked

    Lower Back & Rump

    Olive, unstreaked.

    Wings

    Dark gray. No wing bars or patches. Juvenile often held wings in downward position, tips nearing half-way to tip of tail.

    Breast, Belly, Flanks, Under Tail Coverts

    Yellow beneath from throat to under tail coverts.

    Tail

    Long, square tail. White outer tail feathers. Frequent tail-flicking and splaying.

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

    There was some concern that perhaps the male Hooded Warbler had hybridized with a local Blue-winged or Golden-winged Warbler, so I familiarized myself with all the important field marks of the Hooded juvenile and went into my search with an open mind. This juvenile warbler had all pertinent field marks for a Hooded to my satisfaction. The white outer tail feathers, dark lores, unmarked wings, all yellow underparts and olive back are diagnostic for the species. The behavior was consistent with Hooded Warbler, including the frequent fanning of the tail and tail-flicking.

    Other Notes & Comments

    This report is meant to document the juvenile Hooded Warbler, as I believe the adult male has already been accepted.
