The northern crested newt, great crested newt or warty newt (Triturus cristatus) is a newt species native to Great Britain, northern and central continental Europe and parts of Western Siberia. It is a large newt, with females growing up to 16 cm (6.3 in) long. Its back and sides are dark brown, while the belly is yellow to orange with dark blotches. During the breeding season, males develop a conspicuous jagged crest on their back and tail.
The northern crested newt spends most of the year on land, primarily in wooded areas of the lowlands. In spring, it moves to aquatic breeding sites, mainly larger fish-free ponds. Males court females with a ritualised display and deposit a spermatophore on the ground, which the female then picks up with her cloaca. After fertilisation, a female lays around 200 eggs, folding them into water plants. The larvae develop over two to four months before metamorphosing into terrestrial juveniles (efts). Both larvae and land-dwelling newts mainly feed on different invertebrates.
Several former subspecies of the northern crested newt are now recognised as separate species within the genus Triturus. Its closest relative is the Danube crested newt (T. dobrogicus). It sometimes forms hybrids with some of its relatives, including the marbled newt (T. marmoratus). Although it is currently the most widespread Triturus species, the northern crested newt was probably confined to small refugial areas in the Carpathians during the Last Glacial Maximum.
While the International Union for Conservation of Nature lists the northern crested newt as a species of Least Concern, its populations have been declining. The main threat is habitat destruction, for example, through urban sprawl. The species is also listed as a European Protected Species. Wikipedia →

No species of the same family or order lives in Bucharest, so these are its closest relatives here: other amphibians.
With luck
About 10% of wildlife watchers report a Great Crested Newt sighting in Bucharest on a given day, based on 15 verified sightings from GBIF citizen-science data. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
March and June
In those months about 20% of wildlife watchers report a Great Crested Newt in Bucharest on a given day, against under 5% in July–August and October–February, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Great Crested Newt sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Yes
Of the 5 cities where we can rate Great Crested Newt sightings, Bucharest has the highest daily chance: about 10%. Next come Copenhagen (Denmark, about 10%) and London (United Kingdom, about 10%).
GBIF citizen-science records
It is estimated from how often the Great Crested Newt is recorded against all the amphibians logged in Bucharest (15 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.
