The Eurasian siskin (Spinus spinus) is a small passerine bird in the finch family Fringillidae. It is also called the European siskin, common siskin or just siskin. Other (archaic) names include black-headed goldfinch, barley bird and aberdevine. It is very common throughout Europe and Eurosiberia. It is found in forested areas, both coniferous and mixed woodland where it feeds on seeds of all kinds, especially of alder and conifers.
It can be distinguished from similar finches by its plumage colour. Its upperparts are greyish green and its underparts are grey-streaked white. Its wings are black with a striking yellow wing bar and its tail is black with yellow sides. The male has a predominantly yellow face and breast with a neat black cap. The female and young birds have a greyish-green head and no cap. It is a trusting, sociable and active bird. Its song is a pleasant mix of tweets and trills.
These birds exhibit an unusual migration pattern, migrating southwards in large numbers every few years in winter. The reasons for this behaviour are not known, but they may be related to climatic factors and, above all, the availability of food. This enables overwintering populations to thrive where food is abundant. This small finch is an acrobatic feeder and often hangs upside down like a tit. It will visit garden bird feeding stations.

With luck
About 10% of wildlife watchers report a Eurasian Siskin sighting in Rabat on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 70th most-seen of the 100 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
January and November
In those months about 20% of wildlife watchers report a Eurasian Siskin in Rabat on a given day, against under 5% in April to October, the lowest months. Those are among Rabat's wettest months, with about 80 mm of rain a month against almost none in July.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most Eurasian Siskin sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
41st of 79
Of the 79 cities where we can rate Eurasian Siskin sightings, Rabat ranks 41st at about 10%. The best odds are in Mashhad (Iran, about 40%), Helsinki (Finland, about 30%) and Minsk (Belarus, about 20%).
Same family: Fringillidae
The closest relatives of the Eurasian Siskin that you can see in Rabat (family Fringillidae, Finches, Euphonias, and Allies) are African Chaffinch (about 30%), European Greenfinch (about 20%) and European Serin (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Eurasian Siskin is recorded against all the birds logged in Rabat (14 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.
