The grasshopper buzzard (Butastur rufipennis), breeding in sub-Saharan Africa north of the equator. The grasshopper buzzard forms a superspecies with the white-eyed buzzard (Butastur teesa), rufous-winged buzzard (Butastur liventer), and grey-faced buzzard (Butastur indicus) all of which occur in Asia.
The adult grasshopper buzzard is grey brown above with a darker head and dark shaft streaks on all of its feathers. The feathers of the mantle and lesser coverts are narrowly with fringed rufous in fresh plumage, although this wears off. The grey tail has faint brown bars. The greater coverts and primary feathers are light rufous, the primaries are tipped with black, and form a conspicuous reddish patch in flight. The secondary feathers are rufous shading to dark brown towards the tip, which is white. The chin and throat are whitish, with three black streaks on either side of throat. The breast is rufous and has narrow shaft streaks of black, the belly and thighs are also rufous but lack markings. The axillary feathers are greyish brown, spotted with white or buff. The under wing coverts and wing lining are white. The eyes, legs, and cere are yellow. The... Wikipedia →

With luck
About 10% of wildlife watchers report a Grasshopper Buzzard sighting in Maiduguri on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 57th most-seen of the 65 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
May–June and December–January
In those months about 10% of wildlife watchers report a Grasshopper Buzzard in Maiduguri on a given day, against under 5% in February–April and July–October, the lowest months. Those are among Maiduguri's driest months, with about 25 mm of rain a month against 180 mm in August. November has too few records to rate.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Grasshopper Buzzard sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Maiduguri, in our data
Maiduguri is the only city on Wallace's Line with enough records to rate Grasshopper Buzzard sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Accipitridae

GBIF citizen-science records
It is estimated from how often the Grasshopper Buzzard is recorded against all the birds logged in Maiduguri (6 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.
