Linnaeus specified the type locality as North America, but this has been restricted to the Carolinas following Catesby. The yellow-crowned night heron is now placed together with the extinct Bermuda night heron in the genus Nyctanassa that was introduced in 1887 by the Norwegian born zoologist Leonhard Stejneger.

With luck
About 10% of wildlife watchers report a Yellow-crowned Night-Heron sighting in Tayrona National Natural Park on a given day, based on 189 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 85th most-seen of the 285 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
November
In that month about 30% of wildlife watchers report a Yellow-crowned Night-Heron in Tayrona National Natural Park on a given day, against under 5% in April to July, the lowest months. That is one of Tayrona National Natural Park's wettest months, with about 140 mm of rain against 5 mm in January.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Yellow-crowned Night-Heron sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
23rd of 51
Of the 51 parks where we can rate Yellow-crowned Night-Heron sightings, Tayrona National Natural Park ranks 23rd at about 10%. The best odds are in Caroni Swamp (Trinidad and Tobago, about 50%), Utría National Natural Park (Colombia, about 40%) and Channel Islands National Park (United States, about 30%). All parks ranked.
Same family: Ardeidae

GBIF citizen-science records
It is estimated from how often the Yellow-crowned Night-Heron is recorded against all the birds logged in Tayrona National Natural Park (189 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.
