The Spanish sparrow or willow sparrow (Passer hispaniolensis) is a passerine bird of the sparrow family Passeridae. It is found in the Mediterranean region and south-west and central Asia. It is very similar to the closely related house sparrow, and the two species show their close relation in a "biological mix-up" of hybridisation in the Mediterranean region, which complicates the taxonomy of this species.
The Spanish sparrow is a rather large sparrow, at 15–16 cm (6–6.5 in) in length, and 22–36 g (0.78–1.27 oz) in weight. It is slightly larger and heavier than house sparrows, and also has a slightly longer and stouter bill. The male is similar to the house sparrow in plumage, but differs in that its underparts are heavily streaked with black, has a chestnut rather than grey crown, and has white rather than grey cheeks. The female is effectively inseparable from the house sparrow in its basic plumage, which is grey-brown overall but more boldly marked. The female has light streaking on its sides, a pale cream supercilium, and broad cream streaks on its back.
Two subspecies of the Spanish sparrow – the western Spanish sparrow (P. h. hispaniolensis) and eastern Spanish... Wikipedia →

Rare
Under 5% of wildlife watchers report a Spanish Sparrow sighting in Sierra Nevada National Park on a given day, based on 42 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 98th most-seen of the 153 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
November to March
In those months about 10% of wildlife watchers report a Spanish Sparrow in Sierra Nevada National Park on a given day, against under 5% in April to October, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Spanish Sparrow sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 4
Of the 4 parks where we can rate Spanish Sparrow sightings, Sierra Nevada National Park ranks 3rd at under 5%. The best odds are in Monfragüe National Park (Spain, about 20%) and Doñana National Park (Spain, about 10%).
GBIF citizen-science records
It is estimated from how often the Spanish Sparrow is recorded against all the birds logged in Sierra Nevada National Park (42 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.
