Next Up: #4 Coyote (Canis latrans) vs. #12 Sewer Rat (Rattus norvegicus) #2018MMM
Our combatants advanced entirely unscathed from round 1: Coyote gave up on pursuing a possum while Sewer Rat was very fortunate to have encountered a Moscow Dog that prefers human handouts to hunting #2018MMM
Coyotes have been particularly adept at adapting to human landscapes, and are important at controlling deer, geese, and RODENTS in suburban & urban areas urbancoyoteinitiative.com/10-fascinating… #2018MMM
Sewer rats have also taken to human landscapes with a vengeance, but research by #actuallivingscientist @urbanevol suggests that once rats colonize a city, they repel new incoming rats (and their diseases) nytimes.com/2016/10/28/sci… #2018MMM
Their own behavior changes as well, with Sewer Rats decreasing their movements & staying close to home in urban settings (onlinelibrary.wiley.com/doi/full/10.11…) #2018MMM
In the city, Sewer Rats are numerous & destructive. And they are neophobic (scared of new things), which makes them very difficult to convince to go into traps link.springer.com/article/10.100… #2018MMM
Tonight's battle takes place in... CHICAGO! #AndAllThatJazz #2018MMM
Folks watching at home may want to have this play in the background: #2018MMM
Coyote is on the hunt for his preferred diet in Chicago... RODENT! 42% of the diet (Gehrt 2007) digitalcommons.unl.edu/icwdm_wdmconfp… #2018MMM
Skirting into the alley behind a #NoisyHall, Coyote knows this is prime hunting grounds #AWhoopeeSpot #2018MMM
Sewer Rat freezes, as he did at his last canid encounter, gearing up to BOLT #ILoveMyLife #2018MMM
Coyote RUSH-POUNCES (the most common coyote attack styles are RUSH-POUNCE & POUNCE) (Gese 1996) #NeverFlewSoHigh #2018MMM
Sewer Rat leaps aside & Coyote misses (like they do about 2/3rds of the time)(Blanchard et al. 1986) #ShiverShimmyShake #2018MMM
Sewer Rat dives into the darkness... DEAD END! #BloodCurdled #2018MMM
Coyote is hot on Rat's heels #HoldOnHon #2018MMM
Sewer Rat has only a last resort- ESCALATION! #WeAreGonnaBunnyHug #2018MMM
Sewer Rat about-faces with a "shrieking vocalization" & "jump-attacks" Coyote - "a leaping bite directed toward the head of an opponent" (Blanchard et al. 1986) #NightlyBrawl #2018MMM
Coyote isn't intimdated & POUNCES! Coyote jaws snap onto Sewer Rat & Coyote chomp-chomp-chomps down #PaintTheTown... #RED #2018MMM

Coyote and Virginia opossum last shared a common ancestor 160 million years ago timetree.org kumarlab.net/downloads/pape… #2018MMM
Coyotes are wild dogs (canids) native to North America, closely related to gray, eastern, red and coy wolves. Hybridization and genetic admixture may be facilitated by the fact that they diverged relatively recently. pdfs.semanticscholar.org/845b/c03eca324… @WildCanid #WhyNotWoyote #2018MMM
