KINGMAN – The Arizona Game and Fish Department was monitoring 58 endangered Mexican wolves wearing radio collars at the end of May, the department reported in its latest update.
The overall population of the wolves in the wild in Arizona and New Mexico was 113 at the end of 2016.Annual surveys are conducted by field teams in the winter when the population has the least amount of natural fluctuation. The spring population increases dramatically with the birth of new pups and declines throughout the summer and fall as mortality is particularly high on young pups.
Wolves with functioning radio collars are listed by studbook number in the pack updates. They’re given an identification number preceded by capital M (male) or F (female) .
