Based on reports from local observers, I have recovered the carcasses of 10
dead crows this week: five from Ithaca College grounds and five from the Wood
St - Titus Towers park area. This is a disturbing number of dead crows.
We lost a lot of crows in the past two summers to West Nile virus (maybe 1/3 of
our tagged birds), and we have had a small, but significant number of deaths in
winter roosts from a reovirus over the last few years. Still, 10 dead in one
week is a big number. I cannot help but worry about a poisoning event.
We are working with the Veterinary Pathology department at the Cornell Vet
School to necropsy these birds and have them tested for disease. We would
appreciate hearing about any and all dead crows in the local area.
