Robins are Bigger West Nile Carriers than Crows

DNA analysis of blood taken from 300 mosquitoes trapped in Connecticut during the past 3 years found that 40% had fed on the blood of a robin, while only 1% had fed on crows. Until now, crows had been the prime suspected carrier of the disease that gets passed to humans through the bite of a mosquito that has also fed on an infected bird.

While the study is not an exhaustive study, it does indicate that other birds also carry the virus. The next step in the research will be to catch robbins and actually test their blood.
