Continuing....
However, he decided to see if he could find any more meat, and as soon as he tried to pull a piece free - the other adult appeared, landing almost on top of him and the food! (Still not positive which is which.)
She(?) apparently realized he didn't have anything interesting, and moved off to check the nest cup area. The shading on the tail of the eagle on the left is what's throwing me off - but everything else makes me think this is Surrey Male (SM for short) - and they do sometimes get dirt on their tails, and I suspect that's what's happening here. It sort of looked as if the lower part of the tail might be a bit dirty when he flew in.
SM flew off at 9:14. SF (Surrey Female) puttered around a bit longer, and moved the carcass back nearer the trunk, then she flew off at 9:18 am. It's not visible in the picture of her below, but I did see enough of her tail to be pretty sure my IDs were correct.
I'm always amazed at how late it's light in BC - sunset isn't until 9:19 pm today, and will even get a bit later.
