Red-necked Grebe
Podiceps grisegena

Drawn from a named source but not independently confirmed. Double-check before relying on it.
Size and winter-plumage identification distinctions from horned grebe are directly confirmed against Cornell's own identification/life-history pages. Federal protection is well-established general knowledge. The genuine scarcity/difficulty-of-confirmation at the Chesapeake Bay mouth is directly corroborated via an independent regional birding source describing real observer experience ('hours of scope study... to produce' a confirmed sighting) rather than assumed. Per the brief's own caution against publishing on the strength of a single observation, this entry is deliberately framed as scarce/occasional rather than implied routine — matching its own seasonalPresence: occasional-visitor.
A federally protected diving bird, larger and heavier-billed than the more regularly-present horned grebe — a genuinely scarce Chesapeake Bay winter visitor that birders describe as needing 'hours of scope study' to confirm.
Field marks
- Nearly the size of a mallard — intermediate in size between horned grebe (much smaller) and western grebe.
- In winter: smudgy brown neck, whitish throat, and a long, heavy, mostly yellow bill — the bill size alone is the fastest distinction from horned grebe's much smaller, shorter bill.
- Longer neck than horned grebe, contributing to the size difference between the two.
- Habitat
- Open Bay water in winter, at the mouth of the Chesapeake Bay — a scarcer visitor than horned or pied-billed grebe.
Conservation context
Protected under the Migratory Bird Treaty Act; not managed as a game species.
Similar species — check before you shoot
Identification alone never establishes that a bird may legally be taken. Confirm species (and sex, where a sub-limit depends on it) before shooting.
Ethical shot selection: Given how genuinely scarce this species is in Virginia waters, any large grebe-like bird deserves careful confirmation of bill size/neck length before assuming it's anything else — but since every grebe in this guide is equally protected, the actual shoot/don't-shoot answer never changes: don't.
