Originally posted by Weevil ... there are so many around, but are so hard to photograph...
part of the reason for that is they are seldom actually alone
crows and ravens set up perimeters around the areas they are visiting
if you look you will find birds at varying distances and heights
surrounding ground-feeding crows, for instance
they speak a language of their own
as long as you can hear their simple two note "all clear" you've got a chance of a shot
otherwise you will need a fast long lens
I have speculated that the "eye" of my lens is an active threat to raptors and corvids
(particularly when my "long" lens was a tamron mirror)
much like moving directly towards them
both actions seem guaranteed to push them up and away
