Berks County has recorded its first and Pennsylvania's second case of West Nile virus in a bird.
The American crow was found in Oley Township on July 22, the state's Department of Environmental Protection announced Monday.
The state's first bird with West Nile in 2013, also an American crow, was found in Erie on May 30.
Berks County also recorded Monday its seventh case of West Nile in a mosquito. The latest was found in Birdsboro on July 24. The first was found in Cumru Township on July 10. Others have been found in Bally, and Richmond, Exeter and Washington townships.
Officials sprayed last week for mosquitoes in areas of Exeter and Cumru townships and Shillington in an effort to control the virus, which is most commonly transmitted to humans by mosquitoes.
So far this year, Pennsylvania has not reported any human cases of West Nile.
