Rare
Under 5% of wildlife watchers report a Costa's Hummingbird sighting in Dallas on a given day, based on 23 verified sightings from GBIF citizen-science data. It is the 215th most-seen of the 253 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 Costa's Hummingbird in Dallas on a given day, so our monthly data shows no clear season.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Costa's Hummingbird sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
8th of 8
Of the 8 cities where we can rate Costa's Hummingbird sightings, Dallas ranks 8th at under 5%. The best odds are in Las Vegas (United States, about 40%), Phoenix (United States, about 30%) and Mesa (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Costa's Hummingbird is recorded against all the birds logged in Dallas (23 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.
