The grey-collared becard (Pachyramphus major) is a species of bird in the family Tityridae, the tityras, becards, and allies. It is found in Belize, El Salvador, Guatemala, Honduras, Mexico, and Nicaragua. It has also occurred as a vagrant in Arizona and Texas.
The grey-collared becard was originally described in 1847 as Bathmidurus major. It was eventually placed in its present genus Pachyramphus. That genus has variously been assigned to the tyrant flycatcher family Tyrannidae and the cotinga family Cotingidae. Several early twenty-first century studies confirmed the placement of Pachyramphus in Tityridae and taxonomic systems made the reassignment. In 1998 the American Ornithological Society was unsure where to place the genus and listed its members as incertae sedis but in 2011 moved them to Tityridae.
The grey-collared becard's further taxonomy is unsettled. The IOC, the Clements taxonomy, AviList, and the North American Classification Committee of the American Ornithological Society (NACC) assign it these five subspecies:

Rare
Under 5% of wildlife watchers report a Gray-collared Becard sighting in Guatemala City on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 167th most-seen of the 220 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 Gray-collared Becard in Guatemala City on a given day, so our monthly data shows no clear season.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Gray-collared Becard 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 Guatemala City, in our data
Guatemala City is the only city on Wallace's Line with enough records to rate Gray-collared Becard sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Gray-collared Becard is recorded against all the birds logged in Guatemala City (21 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.
