I don't think it's geeky, we went camping the weekend down at Weymouth and while we were there we visited (ahem) Abbotsbury Tropical Garden Centre and there was some baby swallows in a hole in a tree nesting. We couldn't look for too long as the parents might have been put off, but I would've loved to taken a photo but my hubby thought it might scare them!
But apart from that we have had blue tits nesting in the garden, I love watching out the kitchen window while I'm eating my breakfast in the morning watching the birds as we have a pond with a little puddle off it and they have a bath in it! Always makes me smile, but NOT when they crap on my car
