Over the last several month's I have noticed a severe decline of all bird species that frequent my bird feeders in the yard. This includes the year round birds as well as the migratory and winter over birds. I provide three feeders for the birds, one has black oil sunflower seeds another has regular wild bird seed and I also have suit feeders. The feeders remain full for weeks on end when normally I would have to refill them every day or two this time of year. I thought there was something wrong with the bird feed so I bought new feed and changed it out will no improvement. I spoke with the Volunteer's at Grassy Hollow Visitor Center and they confirmed that the same thing is occuring at their bird viewing station. I used to see woodpeckers, blue jays, scrub jays, quail, chickadees, nuthatches, finches, sparrows, juncho's etc. every day now I rarely see any birds at all. It will be interesting to see the results of this years Audubon Christmas Bird Count and compare to previous years for our area. I worry that some kind of disease or virus is affecting the bird population here and was wondering if anyone else has noticed a decline in bird species.
