Woodside, Portola Valley: Parasite is killing band-tailed pigeons

Original post made on Feb 3, 2015

What about all the other dead birds in our area? I have never seen a dead band-tailed pigeon; but I have seen a number of dead thrushes and a couple of dead robins. If this disease only kills pigeons something else must be killing all these other birds?

I have also seen many many dead thurshes along Tripp Road. I actually reported to Forest and Wildlife Services... they came and picked up a couple as they wanted to investigate. They told me if we see more, to please report , they are investigating...

There is clearly something going on with these birds. We have counted 9 dead birds on our road alone in the last month. I encourage others who see this to report to FWS.

Carriers of West Nile Virus, such as crows, blue jays and squirrels, are of particular concern to the San Mateo County Mosquito and Vector Control District.

West Nile is carried by mosquitoes and mosquitoes bite people, who are vulnerable to the disease.

In 2014, state records show San Mateo County having reported 21 dead birds carrying West Nile, and 15 mosquitoes. There were no cases of transmission to humans.

The district is aware of the dead thrushes, but whatever is killing them is not a concern because it is not a threat to people, a scientist in a district lab told the Almanac.

Dead band-tailed pigeons are also not a concern, for the same reason.
