The broad-billed sandpiper (Calidris falcinellus) is a small wader. The scientific specific name falcinellus is the diminutive from Latin falx, falcis, "a small sickle". It was formerly treated in its own monospecific genus Limicola, but this was found to be embedded within the wider genus Calidris, into which it was transferred in 2004.
Within the genus Calidris, the broad-billed sandpiper is most closely related to the sharp-tailed sandpiper (C. acuminata). The two subspecies are: C. f. falcinellus – breeds northern Scandinavia, northwest Russia; winters east Africa, Middle East, India
C. f. sibirica – breeds central and eastern Siberia; winters southeast Asia Broad-billed sandpipers are small waders, 16–18 cm long, slightly smaller than the dunlin, but larger than the little stint; it has a longer, straighter bill with the tip distinctly kinked down, and shorter legs than dunlin. The breeding adult has dark brown upperparts patterned with narrow, pale feather fringes, and white underparts with blackish markings on the breast. It has a pale crown stripe, and a distinctive double (split) supercilium. As its English name suggests, the bill is slightly broader than... Wikipedia →

Rare
Under 5% of wildlife watchers report a Broad-billed Sandpiper sighting in Istanbul on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 190th most-seen of the 233 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
August
In that month about 10% of wildlife watchers report a Broad-billed Sandpiper in Istanbul on a given day, against under 5% in September to July, the lowest months. That is one of Istanbul's driest months, with about 30 mm of rain against 90 mm in December.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Broad-billed Sandpiper sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
9th of 15
Of the 15 cities where we can rate Broad-billed Sandpiper sightings, Istanbul ranks 9th at under 5%. The best odds are in Kuwait City (Kuwait, about 10%), Karachi (Pakistan, about 10%) and Helsinki (Finland, under 5%).
GBIF citizen-science records
It is estimated from how often the Broad-billed Sandpiper is recorded against all the birds logged in Istanbul (21 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.
