The pallid harrier (Circus macrourus) is a species of harrier, a bird of prey in the family Accipitridae. It breeds in southern parts of eastern Europe and central Asia and Iran and winters mainly in India and southeast Asia. It is a rare but increasing vagrant to Great Britain and western Europe. In 2017 a pair of pallid harriers nested in a barley field in the Netherlands; they raised four chicks, the first recorded breeding of the species in the country. In 2019, a pair bred in Spain for the first time.
This medium-sized raptor breeds on open plains, bogs and heathland. In winter it is a bird of open country. The scientific name is Ancient Greek. Circus is from kirkos (circle), referring to a bird of prey named for its circling flight ('probably the hen harrier), and macrourus is "long-tailed", from makros (long) and -ouros (-tailed).
This is a typical harrier, with long wings held in a shallow V in its low flight. It also resembles other harriers in having distinct male and female plumages. Adults measure 40–48 cm (16–19 in) long with a wingspan of 95–120 cm (37–47 in). Males weigh 315 g (11.1 oz) while the slightly larger females weigh 445 g... Wikipedia →
Rare
Under 5% of wildlife watchers report a Pale Harrier sighting in Tel Aviv on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 187th most-seen of the 232 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 Pale Harrier in Tel Aviv on a given day, so our monthly data shows no clear season.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Pale Harrier sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 8 cities where we can rate Pale Harrier sightings, Tel Aviv ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Vasai-Virar (India, under 5%), Abu Dhabi (United Arab Emirates, under 5%) and Helsinki (Finland, under 5%).
GBIF citizen-science records
It is estimated from how often the Pale Harrier is recorded against all the birds logged in Tel Aviv (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.
