The red-necked grebe (Podiceps grisegena) is an aquatic bird found in the temperate regions of the northern hemisphere. A migratory bird, its wintering habitat is largely restricted to calm waters just beyond the waves around ocean coasts, although some birds may winter on large lakes. Grebes prefer shallow bodies of fresh water such as lakes, marshes or fish-ponds as breeding sites.
The red-necked grebe is a fairly drab dusky-grey bird in winter. During the breeding season, it acquires the distinctive red neck plumage, black cap and contrasting pale grey face from which its name was derived. It also has an elaborate courtship display and a variety of loud mating calls. Once paired, it builds a nest from water plants on top of floating vegetation in a shallow lake or bog.
Like all grebes, the red-necked is a good swimmer and particularly swift diver, and responds to danger by diving rather than flying. The feet are positioned far back on the body, near the tail, which makes the bird ungainly on land. It dives for fish or picks insects off vegetation; it also swallows its own feathers, possibly to protect the digestive system. Wikipedia →

Rare
Under 5% of wildlife watchers report a Red-necked Grebe sighting in Redwood National Park on a given day, based on 76 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 136th most-seen of the 226 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
December to March
In those months about 10% of wildlife watchers report a Red-necked Grebe in Redwood National Park on a given day, against under 5% in April to November, the lowest months. Those are among Redwood National Park's wettest months, with about 310 mm of rain a month against almost none in July.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Red-necked Grebe sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
13th of 22
Of the 22 parks where we can rate Red-necked Grebe sightings, Redwood National Park ranks 13th at under 5%. The best odds are in Elk Island National Park (Canada, about 70%), Riding Mountain National Park (Canada, about 30%) and Great Bear Rainforest (Canada, about 20%).
Same genus: Podiceps
The closest relatives of the Red-necked Grebe that you can see in Redwood National Park (genus Podiceps, Typical Grebes) are Horned Grebe (about 10%) and Eared Grebe (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Red-necked Grebe is recorded against all the birds logged in Redwood National Park (76 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
