Rare
Under 5% of wildlife watchers report a Malagasy Spinetail sighting in Antananarivo on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 55th most-seen of the 69 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 a Malagasy Spinetail in Antananarivo on a given day, so our monthly data shows no clear season.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Malagasy Spinetail sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Antananarivo, in our data
Antananarivo is the only city on Wallace's Line with enough records to rate Malagasy Spinetail sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Malagasy Spinetail is recorded against all the birds logged in Antananarivo (17 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.
