With luck
About 10% of wildlife watchers report a Chihuahuan Raven sighting in Ciudad Juárez on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 56th most-seen of the 70 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
January and April
In those months about 20% of wildlife watchers report a Chihuahuan Raven in Ciudad Juárez on a given day, against under 5% in March, May–June and September–November, the lowest months. Those are among Ciudad Juárez's driest months, with about 10 mm of rain a month against 50 mm in July.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Chihuahuan Raven 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 Ciudad Juárez, in our data
Ciudad Juárez is the only city on Wallace's Line with enough records to rate Chihuahuan Raven sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Chihuahuan Raven is recorded against all the birds logged in Ciudad Juárez (13 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.
