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 Sian Ka'an Biosphere Reserve on a given day, based on 57 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 187th most-seen of the 288 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
January
In that month about 10% of wildlife watchers report a Gray-collared Becard in Sian Ka'an Biosphere Reserve on a given day, against under 5% in February to December, the lowest months. That is one of Sian Ka'an Biosphere Reserve's driest months, with about 55 mm of rain against 230 mm in June.
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.
3rd of 5
Of the 5 parks where we can rate Gray-collared Becard sightings, Sian Ka'an Biosphere Reserve ranks 3rd at under 5%. The best odds are in Cumbres de Monterrey National Park (Mexico, about 10%) and Montes Azules Biosphere Reserve (Mexico, under 5%).
GBIF citizen-science records
It is estimated from how often the Gray-collared Becard is recorded against all the birds logged in Sian Ka'an Biosphere Reserve (57 verified sightings from 2019 to 2026), 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.
