RICHARD FAGERLUND: Coyotes, bats do more good than harm
Richard Fagerlund;rrobserver.com
There is a lot of talk about removing the coyotes from the Corrales area. That would be a major mistake. Coyotes in urban areas such as Corrales feed primarily on rodents and rabbits. If we eliminate coyotes from the area we will develop several other problems. This applies to Rio Rancho and other localities in the area.
Deer mice (Peromyscus spp.) are common in the area and several species are known vectors of Hantavirus. If we deplete the coyote population, the number of deer mice will multiply significantly and could create severe health problems if they become established in sheds or other buildings that are infrequently used.
There is more. Of the 107 species of fleas found in N.M., 33 species are vectors of the plague. The most important plague vector is a rock squirrel flea (Oropsylla montana). This flea also feeds deer mice, pack rats, field mice, squirrels and rabbits. All of these animals are in the coyotes' diet and all are found in Sandoval County.
If we don't maintain a natural control of these animals, they will expand and could very possibly cause major problems with the plague in the areas. If the rodent population increases, cats and dogs will interact with them and can pick up their fleas and bring them in your homes. Cats are very susceptible to the plague and can suffer. Dogs have a resistance, but can still carry the fleas.
Of the 107 species of fleas found in New Mexico, 54 species are found in Sandoval County. We really need to leave the coyotes alone as they are the best natural control for fleas we could have. If we put rodenticides out for rodents, then the fleas will leave their dead bodies and attack our pets or other animals. We won't solve any plague problems with poisons. Coyotes are the best natural method for controlling rodents. If we remove the coyotes, we are asking for cases of Hantavirus and plague.
We are also increasing our chances for getting plague and Hantavirus when we allow some people to go out and shoot coyotes for the fun of it. We have to eliminate these ridiculous coyote-killing contests for several reasons: because it is increasing our chances of getting a serious rodent-borne disease and because it is totally unnecessary for any reason except to inflate the ego of someone who has too much time on his hands.
There is another animal that is very much maligned in the state: the bat. A lot of time when someone sees a bat, they panic and call animal control. The truth is that there are 25 species of bats flying around somewhere in New Mexico every night, trying to make a living. Only 1 percent of the bats are possibly rabid. If you see a bat that appears lethargic or is flying around in the day time, it may be infected and you shouldn't go near it. The vast majority of them do not carry the disease.
Also, a single bat can eat up to 1,000 mosquitoes in one night. That is a lot of disease control as there is a much higher percentage of disease vector mosquitoes than there are rabid bats.
Bats are far more beneficial than they are dangerous. Coyotes are in the same league.
Let's focus on eliminating drunk drivers, sexual predators and child molesters and leave these beneficial animals alone.
