Lung from a captive, adult male, 930-g Gyrfalcon, found dead in WA

Lung from a captive, adult male, 930-g Gyrfalcon, found dead in Washington, USA.  Lung shows diffuse severe congestion and edema.  

The falcon became ill and died after consumption of a (presumptively) HPAI virus-infected American wigeon (Anas americanus) from Wiser Lake in Washington, USA. Waterfowl carrying HPAI viruses were detected at Wiser Lake in December 2014, near the beginning of a poultry epizootic in North America caused by HPAI.
