[Ontbirds]Dead Bohemians and live Pine Grosbeaks in Midland

[Adam Zita]

Just want to report that there are about 3 Pine Grosbeaks that have been
around the Wye Marsh visitor centre for the past week and half and one is a
russet variant.

Also,

I got a call at Wye Marsh late Tuesday from a man who said he had about four
dead birds on his lawn and his neighbour's lawn. So I went over after work
being the curios birder that I am.  I ID one bird as a Bohemian waxwing, but
did not see the other birds he spoke of as they had already been 'dealt
with' He was worried about finding this many dead birds around his house.  I
am not a biologist by any means but I tried to think of some possible
reasons for these dead birds - cats, maybe, but the birds had no outward
markings.  There wasn't a window they would have flown into.  So, my theory
is that they died from eating fermented berries.  There are two
big-mountain-ash trees on both of their front lawns and the birds were found
directly underneath these trees, 

Has anyone experience this before and if so (or if not) do you think I am
right or way out in left field?

Curiously yours, Adam Zita
