To report incidents of take or harassment of wolves, please call the AGFD 24-hour dispatch (Operation Game Thief) at (800) 352-0700.
Overall Mexican Wolf Recovery Program Monthly Update
The U.S. Fish and Wildlife Service posted the 2017 Mexican Wolf Initial Release and Translocation Plan (Plan) on the Mexican Wolf Recovery Program Website and requested comments for 20 days. The USFWS provided all comments received in applications to New Mexico Department of Game and Fish for importation and release permits consistent with the Plan.
The USFWS hosted the Canid and Hyaneid Taxon Advisory Group meeting in Albuquerque March 27 and 28, 2017. This meeting was part of the larger Association of Zoos and Aquarium's mid-year meeting hosted by the Albuquerque Biological Park.
The Division of Genomic Resources (DGR) of the Museum of Southwestern Biology at the University of New Mexico serves as the repository for Mexican wolf specimens including carcasses, pelts, and blood. On March 30, 2017, DGR celebrated migrating from maintaining specimens in -80oC freezers to new, more secure cryogenic nitrogen-vapor (-190oC).
Numbering System: Mexican wolves are given an identification number recorded in an official studbook that tracks their history. Capital letters (M = Male, F = Female) preceding the number indicate adult animals 24 months or older. Lower case letters (m = male, f = female) indicate wolves younger than 24 months or pups. The capital letter “A” preceding the letter and number indicate breeding wolves.
Our note: You will notice that some of the wolves also have names associated with their identification numbers. For the last five years we had a Pup Naming Contest for Kids to name the pups born in the Spring. The names that you see are the winning names that we have assigned to the pups. Follow these links for all the entries and results from the 2012 contest, 2013 contest, 2014 contest, 2015 contest and 2016 contest.
Definitions: A “wolf pack” is defined as two or more wolves that maintain an established territory. In the event that one of the two alpha (dominant) wolves dies, the remaining alpha wolf, regardless of pack size, retains the pack status. The packs referenced in this update contain at least one wolf with a radio telemetry collar attached to it. The Interagency Field Team (IFT) recognizes that wolves without radio telemetry collars may also form packs. If the IFT confirms that wolves are associating with each other and are resident within the same home range, they will be referenced as a pack.
CURRENT POPULATION STATUS
The IFT completed the annual year-end population survey which started in November 2016 and concluded with helicopter count and capture operations conducted in late January through early February 2017. The IFT documented a minimum of 113 Mexican wolves in the wild in Arizona and New Mexico at the end of 2016. At the end of March, there were 61 wolves with functioning radio collars that the IFT was actively monitoring. Wolves with functioning radio collars are listed by studbook number in the pack updates below.
Annual surveys are conducted in the winter as this is when the population experiences the least amount of natural fluctuation (i.e. in the spring the population increases dramatically with the birth of new pups and declines throughout the summer and fall as mortality is particularly high on young pups). Thus, the IFT summarizes the total number of wolves in the winter at a fairly static or consistent time of year. This allows for comparable year-to-year trends at a time of year that accounts for most mortality and survival of young pups.
Bear Wallow Pack (collared Poco-AM1338, Bailey-AF1335 and Zyanya-fp1548)
In March, the Bear Wallow Pack was located within their traditional territory in the east central portion of the Apache-Sitgreaves National Forest (ASNF).

In March, the Bluestem Pack continued to use their traditional territory in the east central portion of the ASNF. F1488 continued to travel separate from the Bluestem Pack with another wolf near Alpine. During March, M1382 continued to be documented traveling with AF1339 of the Panther Creek Pack. Genetic analysis from the male pup initially thought to be Panther Creek mp148X revealed that it was a Bluestem pup and has been assigned the studbook number mp1574.
Elk Horn Pack (collared AF1294, AM1342, Blaze-mp1471, River-mp1474, and Dajanae-fp1473)
In March, the Elk Horn Pack was located within their traditional territory in the north eastern portion of the ASNF. The female pup assigned the temporary studbook number, fp147X, was identified as fp1473 through genetic analysis. This confirmed that the wolf was a wild born of the Elk Horn Pack and not a cross-fostered pup from 2016.
Frieborn Pack (collared F1443 and Mago-m1447)
In March, F1443 and m1447 received pack status and were named the Frieborn Pack. They have been holding a territory in the east central portion of the ASNF in Arizona and into New Mexico.
Hawks Nest Pack (collared AM1038)
The Hawks Nest Pack consists of one collared wolf, AM1038. AM1038 previously made wide dispersal movements within the north central portion of the ASNF, but during March was consistently located in the northern portion of the ASNF in the territory of the Diamond Pack. By the end of March, AM1038 was documented traveling primarily with f1557 of the Diamond Pack.
Hoodoo Pack (collared Copper-AM1290, Verde-AF1333, Kiko-m1441, Willow-fp1549, Moon Beam-fp1550 and Lupin-f1567)
In March, the Hoodoo Pack was located within their traditional territory in the north central portion of the ASNF. Sub-adult wolves m1441 and f1567 continued to travel together and apart from the Hoodoo Pack. The IFT concluded the prey carcass investigations that began in February looking at the kill rates of both the Hoodoo Pack and the new pair: m1441 and f1567. In March, fp1549 was located dead in Arizona. The incident is under investigation.
Maverick Pack (collared Sandy-AF1291)
In March, the Maverick Pack was located within their traditional territory both on the FAIR and east central portion of the ASNF.
Panther Creek Pack (Esperanza-AF1339, Rakesh-mp1483, Centinela-fp1484, and Da-Kari-mp1486)
In March, the Panther Creek Pack was located in the east central portion of the ASNF. Bluestem M1382 continued to be located traveling with AF1339. Pups mp1483, fp1484, and mp1486 have been traveling separately from the rest of the pack. Male pup 1486 has been documented traveling in the Gila National Forest (GNF) in New Mexico. Male pup 1483 was documented traveling between Arizona and New Mexico. The male pup assigned the temporary studbook number, mp148X, was identified through genetic analysis as a Bluestem animal, and has been given a new studbook number of mp1574.
ON THE FAIR:
Diamond Pack (collared Phoenix-f1557, Aleu-mp1559, Spirit-fp1560, Ulv-fp1570, Rio Espiritu-mp1571 and Argentum-mp1572)

Near the beginning of the month, mp1572 was located lame and removed for veterinary care. Male pup 1572 has tested negative for diseases and has been transferred to the Sevilleta National Wildlife Refuge in New Mexico where it continues to receive rehabilitative care. Near the end of March, AM1038 of the Hawks Nest Pack and f1557 were documented traveling together and apart from the Diamond Pack.
