The great reed warbler (Acrocephalus arundinaceus) is an insectivorous bird in the family Acrocephalidae. It is a medium-sized passerine bird and the largest of the warblers. It breeds throughout mainland Europe and the Western Palearctic and migrates to sub-Saharan Africa in the winter. It favours reed beds during the breeding season, while living in reed beds, bush thickets, rice fields, and forest clearings during the winter. It exhibits relatively low sexual dimorphism, and the sexes are similar in appearance. This species mates both polygynously and monogamously.
The great reed warbler was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae. He placed it with the thrushes in the genus Turdus and coined the binomial name Turdus arundinaceus. He specified the type locality as Northern Europe. Linnaeus based his entry on the Turdus musicus palustris or Bruch Beiden Rohr Drossel that had been described in 1750 by the German naturalist Jacob Theodor Klein in his book Historiae avium prodromus. The specific epithet arundinaceus is Latin meaning "like a reed" (hence "of the reeds"), from arundo, arundinis meaning... Wikipedia →

Rare
Under 5% of wildlife watchers report a Great Reed-Warbler sighting in Kigali on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 236th most-seen of the 244 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Great Reed-Warbler in Kigali on a given day, so our monthly data shows no clear season.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Great Reed-Warbler sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
25th of 28
Of the 28 cities where we can rate Great Reed-Warbler sightings, Kigali ranks 25th at under 5%. The best odds are in Yerevan (Armenia, about 10%), Kuwait City (Kuwait, about 10%) and Kyiv (Ukraine, about 10%).
Same genus: Acrocephalus
The closest relatives of the Great Reed-Warbler that you can see in Kigali (genus Acrocephalus, Reed Warblers) are Lesser Swamp Warbler (about 10%) and Eurasian Reed-Warbler (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Great Reed-Warbler is recorded against all the birds logged in Kigali (6 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.
