Détails de l'observation
A stocky, big-headed hummer with proportionately short bill, and a smoothly margined large central red gorget patch. An immature male Ruby-throated Hummingbird is rather similar, but usually lacks as large a gorget patch and if so the patch will not be as smoothly margined and typically more basally located. A white supercilium is present, which is usually lacking in Archilochus hummers. The bird has a "vest" with a rather "chickenwire" pattern formed by fairly well developed pale fringes to the flank feathers, a pattern usually not as well developed in an immature Archilochus. The tail appears unforked, unlike an immature male Archilochus. In some of the attached photos, P6 appears much too blunt for a male Archilochus. The lower orbital feathers are not as dark as those of immature male RTHU's, whose dark orbital feathers will become a component of the dark "mask" of an adult. Observed at private address.
