I say you keep them there. They will only be there for awhile and they cant bother you that much. To avoid the birds coming back the next year, put something to block them from being able to make a nest. This is much better then knocking over the nest that took them so long to make.
You may, on the other hand, want to consider the damage that they could be doing to your home, as well as the over 60 diseases that their droppings can carry. Many of the diseases caused by bird droppings are caused by an airborne fungus, which, if allowed to circulate in your home, greatly increases your health risk.
You can evict the birds, perhaps with a Transonic Pro (http://www.bird-x.com/trans.html). It plays both sonic and ultrasonic sounds that makes birds feel extremely uncomfortable, which will probably cause them to leave. Visit http://www.bird-x.com for more information.
We've had been dealing with this same problem for 6 months now. A family of sparrows made themselves a home on the overhang of our roof top. We've tried soaking their nest with water and tearing it down (while they were building it). Our pest control company advised that we purchase one of those plastic rotating head owls to drive them away. To our dismay...this did not work! Finally our home builders mentioned that we purchase "foam insulation" from our local hardware outlet and seal it; making it an inconvience to roost. Once the foam insulation had dried, we were able to cut, carve and paint it. We are proud to say, "That we FINALLY have a sparrow-free home." :-D
I have tried everything to get the birds out of our yard because they poop all over the pool and in the pool.
the owl, didn't work, the shiny disks, the wind chimes, the Alligator, the snake, the tin pans, the music, the noise.
what finally worked is fishing line. I read one person suggested it and it totally works. I strung the fishing line in a random pattern, from tree to gutter to post to spot light, you name. it creats a net or screen and the birds totally stay away.
I then put pcp pipes at the corners of the fence that surround the pool and i strung the fishing line between those and then even made the fence appear higher.
the birds stopped coming around that day. it was wonderful to finally see the poop stop.
One way to get rid of sparrows is to get rid of all of your bird feeders and trees around your home. You can also try putting out moth balls. It is illegal to kill the sparrows.
House Sparrows tend to nest in and around buildings. They scavenge around domestic rubbish and also eat seeds. They are definitely attracted to bird feeders. They feed their young on small insects and inveterbrates.
House sparrows are about 6.25 inches long and have a wingspan of about 9.5 inches. They weigh around 1 ounce.
You can destroy it or put it back where it came from. Since house sparrows are not native they are excluded by the migratory bird act.
yeahhh
Sparrows originally came from China. But, the climate started to change, and the sparrow migrated to North America. Today, the climate in China is slowly changing, but there is still very little sparrows there. (About 2%)
Passer domesticus
Omnivore
No there has been no bad omens from flinging sparrows.
That depends on how long the sparrow lives. House sparrows have 1 clutch per year. They usually have around 6 eggs per clutch. If it lives for 6 years it would have around 36 offspring. Of course during those 6 years some eggs would break and some of the young would die so it would be less 36.
the house sparrow nest has three to six eggs
Yes, it is extremely common.
The House Sparrow is monogamous and mates for life .
