The green-striped brushfinch (Arremon virenticeps) is a species of bird in the family Passerellidae, the New World sparrows. It is endemic to Mexico. The green-striped brushfinch has a complicated taxonomic history. It was formally described in 1855 with the binomial Buarremon virenticeps. The genus Buarremon was later merged into genus Atlapetes but further study resulted in Buarremon's being resurrected. Buarremon virenticeps was for a time assigned as one of many subspecies of what was then the "stripe-headed brushfinch" (Buarremon torquatus) but was soon restored to full species status. In 2008 taxonomists began merging Buarremon into Arremon.
The green-striped brushfinch's further taxonomy is unsettled. The IOC, AviList, and BirdLife International's Handbook of the Birds of the World treat it as monotypic. This article follows the monotypic species model. The green-striped brushfinch is about 17 to 19 cm (6.7 to 7.5 in) long and weighs 31 to 39 g (1.1 to 1.4 oz). The sexes... Wikipedia →

Rare
Under 5% of wildlife watchers report a Green-striped Brushfinch sighting in Mexico City on a given day, based on 92 verified sightings from GBIF citizen-science data. It is the 223rd most-seen of the 332 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 Green-striped Brushfinch in Mexico City on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Green-striped Brushfinch sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Mexico City, in our data
Mexico City is the only city on Wallace's Line with enough records to rate Green-striped Brushfinch sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Passerellidae
The closest relatives of the Green-striped Brushfinch that you can see in Mexico City (family Passerellidae, New World Sparrows) are Canyon Towhee (about 60%), Song Sparrow (about 40%) and Chipping Sparrow (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Green-striped Brushfinch is recorded against all the birds logged in Mexico City (92 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.
