This is what Ben Huberman says about this weeks photo challenge at The Daily Post,

This week, share a photo of something marked by its weight — or its air of weightlessness. Show us gravity at its most unforgiving, or most generous. Bricks or feathers. A collapsed ruin or a plane taking off. A heavy piece of old furniture or the flying buttresses of a cathedral. Keep in mind that weight doesn’t even have to be physical: emotions and memories can weigh on us (or lift our spirits) at least as much as real objects.

I found this really difficult and couldn’t come up with anything original, but I suppose if wouldn’t be a challenge if it was too easy!
And then this afternoon as I walked the dogs in the cemetery, I listened to birdsong all around me. As well as the small songbirds, there was the call of the jay and I failed to photograph it yet again. Pigeons made their gentle cooing sound, seagulls shrieked and then the crows joined in. There are lots of crows in the graveyard, I’ve always thought them most appropriate. So they reminded me of a possibility, and I headed for the tall, bare trees where they nest.

It’s way too early for any eggs, even in this mild winter, so the nests appear to be weightless, suspended on the most delicate of branches. In just a few months those branches will be full of activity and weighed down with another generation of crows.
