The long-toed salamander (Ambystoma macrodactylum) is a mole salamander in the family Ambystomatidae. This species, typically 4.1–8.9 cm (1.6–3.5 in) long when mature, is characterized by its mottled black, brown, and yellow pigmentation, and its long outer fourth toe on the hind limbs. Analysis of fossil records, genetics, and biogeography suggest A. macrodactylum and A. laterale are descended from a common ancestor that gained access to the western Cordillera with the loss of the mid-continental seaway toward the Paleocene.
The distribution of the long-toed salamander is primarily in the Pacific Northwest, with an altitudinal range of up to 2,800 m (9,200 ft). It lives in a variety of habitats, including temperate rainforests, coniferous forests, montane riparian zones, sagebrush plains, red fir forests, semiarid sagebrush, cheatgrass plains, and alpine meadows along the rocky shores of mountain lakes. It lives in slow-moving streams, ponds, and lakes during its aquatic breeding phase. The long-toed salamander hibernates during the cold winter months, surviving on energy reserves stored in the skin and tail.
The five subspecies have different genetic and ecological histories, phenotypically expressed in a range of color and skin patterns. Although the long-toed salamander is classified as a species of Least Concern by the IUCN, many forms of land development threaten and negatively affect the salamander's habitat. Wikipedia →

Rare
Under 5% of wildlife watchers report a Long-toed Salamander sighting in Vancouver on a given day, based on 32 verified sightings from GBIF citizen-science data. It is the 9th most-seen of the 11 amphibians we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
February, June and October–November
In those months about 10% of wildlife watchers report a Long-toed Salamander in Vancouver on a given day, against under 5% in March–May, July–September and December–January, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Long-toed Salamander sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 cities where we can rate Long-toed Salamander sightings, Vancouver ranks 3rd at under 5%. The best odds are in Seattle (United States, about 10%) and Portland (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Long-toed Salamander is recorded against all the amphibians logged in Vancouver (32 verified sightings), 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.
