Ornithology probably doesn't really describe a few postcards of birds, but the letter B went to bridges, so here we are with ornithology.
I am particularly fond of robins because of childhood memories of gardening with my father, when our semi-tame robin would come to oversee.
I've included the puffin and owls because they make me smile. I've never met a puffin in real life but an owl did once visit the house where we were staying for a holiday. I don't know who was more surprised.
The egrets are there for their sheer beauty.
