My bigma turned up yesterday but it rained and rained and I couldn't play till today, I set up my tripod besides the patio table and chairs

and pointed the bigma at the bird table on our grassy bit.
No sooner had I sat down I spotted a b.o.p circling overhead, I grabbed the bigma/tripod and went running off down the garden path, through the gate onto the lawn and pointed everything up. Got this one slightly dodgy shot just before it disappeared over the tree's, any idea's? I only know kestrels and have to see them from the front
Within in a few minutes it [or another] was back with a partner circling really high this time before disappearing for good.
Cheers
Brian.
P.S. Love the Bigma
