We tried out our new bird feeder for the first time using a seed mix for finches. It was immediately inundated with sparrows by the dozen who drained the whole thing in a day, pooping everywhere in the process.
We were hoping to attract some other species that we know are around such as cardinals, blue jays, mourning doves, house finches, mockingbirds, etc. Perhaps another type of food would be better. I've heard that sparrows won't eat Nyjer thistle seed. Like starlings, pigeons and seagulls, these birds are already so numerous in this area that they need no extra help.
At this point, I'm at a loss as to how to proceed. How to promote bird diversity in the city? I've read that sometimes sparrows will alert other species to the feeder and perhaps their poop could be nutritious in the compost.
Do we continue allowing the crazed barrage of sparrows? Try a different seed mix? Save the food until a better time for different birds? I'll have to do some more research.
