This is interesting it’s an incidence of drunk blackbirds. I had been unaware that birds could get drunk from fermenting berries but it appears that they can. 12 blackbirds in Cumbria were found dead with trauma injuries. A post mortem found that one of the birds had high levels of ethanol in its liver. It seems that all the dead birds had eaten berries from a nearby rowan tree which had fermented in the gut causing them to turn into alcohol. One of the birds which was found to be unsteady on its feet was treated at a local wildlife centre and later made a full recovery.
