Likely
About 40% of wildlife watchers report a Water Thick-knee sighting in Queen Elizabeth National Park on a given day, based on 712 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 33rd most-seen of the 434 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
May and July
In those months about 50% of wildlife watchers report a Water Thick-knee in Queen Elizabeth National Park on a given day, against about 30% in March, August and October, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Water Thick-knee sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
7th of 40
Of the 40 parks where we can rate Water Thick-knee sightings, Queen Elizabeth National Park ranks 7th at about 40%. The best odds are in Lower Zambezi National Park (Zambia, about 50%), Gonarezhou National Park (Zimbabwe, about 50%) and Mana Pools National Park (Zimbabwe, about 50%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Water Thick-knee is recorded against all the birds logged in Queen Elizabeth National Park (712 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.
