"For a little more than the past two years(2017-present), National Park Service researchers and volunteers in Los Angeles collected coyote scat at 27 sites, most of them in LA, including spots coyotes frequent in Griffith Park, Boyle Heights, Eagle Rock, Frogtown, Beverly Hills, Culver City and Baldwin Hills"............"In all, the research team collected and dissected more than 3,200 samples.........Investigating their diet is one part of a larger NPS coyote study from the Santa Monica Mountains National Recreation Area, dubbed the L.A. Urban Coyote Project"........."The overall goal is to better understand how the estimated 5,000 Los Angeles Coyote population has managed to carve out such a comfortable spot in the densely human populated, urban ecosystem we share together".........."The research reveals that in the city of Los Angeles and western northwest suburbs(1000 Oaks), the Coyote diet consists of----Read as City % first figure and suburb % 2nd figure): Human and pet foods 26% 8%,,,,, Rabbits 18% 48%..... Pocket gophers 9% 13%,,,,,, Ornamental fruits 26% 24%,,,,, Insects 19% 15%,,,,, Domestic cats 20% 4%"............."The bottom line is that City dwelling Coyotes depend heavily on human created food(garbage/pet food and cats) whereas suburban Coyotes lean toward rabbits and rodents, with both city and suburban canids loving fruit"............"From 1996-2004, the (NPS) biologists also studied coyote populations in Thousand Oaks, Agoura Hills and Calabasas in suburban Los Angeles and Ventura Counties".........."This study involved the capture and radio-collaring of 128 coyotes".......... "Coyotes were found to be present and in relatively high densities in almost all of the remaining natural habitat fragments throughout the study area"............."Although coyotes will visit the surrounding urban areas, they were found to prefer spending time in the natural open space"............"However, many of the remaining fragments around Thousand Oaks, Agoura Hills and Calabsas are too small to support a family group of coyotes, and therefore these groups must include multiple fragments within their home range"..........."To use these fragmented patches, coyotes are forced to travel through developed areas, including crossing roadways of various sizes".........."Some habitat fragments have become separated by large networks of urbanization so that even home and apartment dwellers not on the edge of natural areas may come into contact with coyotes as they move between these natural habitat patches"..........."However most of the coyotes that occur in these patches are rarely seen by the citizens living around them"..........."They tend to be very secretive, which has allowed them to persist in these urbanized areas"............... "In this suburban region of Los Angeles, Coyote diet consisted mainly consist of native fruits and small mammals such as rabbits, woodrats, and mice"..........."These suburban coyotes only occasionally utilized human food sources, most predominantly ornamental or non-native fruits which can constitute up to 25% of their diet".........."Other items such as trash, pet food and domestic pets may also be consumed on occasion, but constitutes a very small percentage of coyote diets in this study area"......... "The number one source of mortality in the study area was vehicle collisions".......... "Roads act as a barrier to movement and gene flow, as well as a direct source of mortality". The surprising find was that the next most important source of mortality for coyotes in the study area are rat poisons"............."Canids (a.k.a. dog species) are very vulnerable to the effects of anticoagulant rat poisons, the most commonly used method of rodent control worldwide"............"Coyotes are likely secondarily exposed to the poisons, meaning that they are consuming the small rodent pest species that people are targeting with the poisons"............"These poisons have a delayed action so that once a coyote eats the poisons, it can take up to 10 days for them to die"
