The Spanish imperial eagle, Spanish eagle, Iberian imperial eagle or Adalbert's eagle (Aquila adalberti) is a species of eagle native to the Iberian Peninsula. The binomial commemorates Prince Adalbert of Bavaria. Due to its distinct "epaulettes", old literature often referred to this species as the white-shouldered eagle.
Formerly, the Spanish imperial eagle was considered to be a subspecies of the eastern imperial eagle, then known simply as the imperial eagle, but is now widely recognised as a separate species due to differences in morphology, ecology, and molecular characteristics.
This is a large raptor and quite large eagle, broadly similar in size to its cousin, the eastern imperial eagle, which is found in a considerably different distributional range. Compared to sympatric largish booted eagles, it is somewhat smaller than the golden eagle and somewhat larger than Bonelli's eagle. Spanish imperial eagles can weigh from 2.5 to 4.8 kg (5.5 to 10.6 lb). The average weight of males in a sample of 10 was 3.19 kg (7.0 lb) while that of 17 females was found to be 3.43 kg (7.6 lb). Meanwhile, another sample of 10 unsexed adults weighed an average of 3.93 kg (8.7... Wikipedia →

Rare
Under 5% of wildlife watchers report an Adalbert's Eagle sighting in Madrid on a given day, based on 175 verified sightings from GBIF citizen-science data. It is the 115th most-seen of the 196 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Adalbert's Eagle in Madrid on a given day, so our monthly data shows no clear season.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Adalbert's Eagle sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Madrid, in our data
Madrid is the only city on Wallace's Line with enough records to rate Adalbert's Eagle sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Adalbert's Eagle is recorded against all the birds logged in Madrid (175 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.
